Porsche 924 Turbo: Tireremo fuori oltre 400 CV? - Davide Cironi (Dal Pollaio alla Pista Ep.2-3 SE03)
My name is Davide Cironi, class of 1987 and my job is to drive the most incredible cars in history I had to invent a trade from scratch, it was hard But today I'm making my dreams come true one powerslide after another The one that absolutely gives me the most taste though is giving a second chance to cars that no one would bet a dime on And making them badass I like to take them from the barn and bring them to the track Whether it is really a barn or simply a state of neglect, it matters little In every project I involve the best workshops in Italy And we put down killer cars. This is "From the Barn to the Track" 924 Turbo interesting How did this one end up there, license plate Varese? I don't have a clue The color is beautiful Yes Rim size is already the right one, more or less They are 8x16 in the rear Oh not bad front 7x16 That is, they fit good as a width Shall we try to open? Let's try Too much is missing here the filter case, injection, injectors Yes. Injectors... there is nothing
This was disassembled and put here Watch out for some mice coming out LPG system No She was fitted with the LPG system No, I don't believe it What an ugly thing This one almost takes a miracle to get it going Do we leave it where it is? No, no, we take it We save it We save her, poor little thing Porsche emblems They had a certain build quality they resist to anything see if there is any key, anything, in there what a smell... smell this There are the keys Please You won't believe it, it opened Non-existent seals, weighs a quintal I believe it But look at what they gave us for free, though? A very good pole to hold it up Here I see some rot on the lock, so it's a miracle it opened Do you see just some of it? Look what I found for you So sad We already have the vest XL should also fit you Yes, yes then I'll put it on Look, like my Doblò Oh it still works, but maybe it's for picnics Drag racing type Adjustable, see? Incidence There is also a fairly worthy muffler Yeah, they punked it up a little bit This is the definitive signal of bad Saturday nights this poor Porsche had to go through. It has the additional instruments, sport steering wheel, sport pedals The steering wheel is Isotta, do they still exist? That is, somewhere they are still alive The seats in the back look good to me Listen to this A little castor oil and it goes well That's nice Let's close The rear window is coming off the frame I'm afraid if we break this one it will be almost unobtainable It seems to be quite a disaster, as usual I think this mission is almost impossible How long has this car been here? If I understand correctly, 5 or 6 years at least I mean she was definitely dumped at the time when 924 was worthless Yes, most likely they must have had problems They tried to run it a little bit on LPG. Also because there were times when there were some incentives for those who put these systems in They probably just brought it here finished, destroyed Also because look at this, it's all dented, the skirt is blown off She hit some walls, some posts I guess it made a bad life this car It has to be saved Whatever, so what is to be done? Shall we call someone to come and take it away? Tractor power Eye on the door It's pretty nailed down, right? The whole luggage rack moves I thought worse under some scattered rust This must have been a little wall outside the disco I think so Excuse me, would you give us a hand to fix it? Well you see, when you take them out then you start to see everything Bravo Check this out The higher you raise them, the worse they get We are in this beautiful country, in this Neapolitan country We go around with this beautiful car My roots, also here are my roots Where the f**k are we going? Already running And I guess you have to go towards me a little bit I started messing around with engines, starting with scooters Until I started breaking myself too many bones I get my license, I bought a Uno Turbo, the first one, which I still have And like all geeks with Uno Turbos, the first thing they do: they break third gear My studies were computer science, so not even the 10 wrench I had I took the car to the mechanic who took 350,000 lire to fix the third gear synchronizer on the Uno Turbo I go out to the mechanic: first, second, third, gearbox breaks again. And I say: "I guess if I want to keep the Uno Turbo, I have to learn how to fix it myself".
And it all started there, with the Uno Turbo. I sound placid today, but when I was young, as we say in Naples, I had "The head to part my ears" For the area they called me "Little Silvio the criminal" Back then, with the first accesses on the forums, This friend told me to use "Turbo Crime" as my nickname And that's where it all started, with the Uno Turbo with Turbo Crime and everything else. I try to do only certain jobs, done well, I like challenges I try to do things, as it were, a little outside the lines For me Silvio in Italy is the excellence I met Silvio back in 1999 I had the famous MK3, already Turbo converted But I needed refined electronics, because it couldn't handle air conditioning I saw right away that he was very capable, and I brought him the car to install these new electronics And since then he bonded with this car However, we had so many merits and successes When Massimo arrived with this car He kind of saw it as the car of sundays, for fun We never thought that the Golf could be a car for making high numbers We wanted to build a special project, something unique We worked on it for two years, then much, much more time To get to the result that we are now Let's get this hood off so we can go comfortably to work This is free I would try to put a battery Will it explode in your opinion? I'm going to walk away We give power to our emotions Go let's turn on the ignition It will not be able to start because it misses half of the engine parts Let's see if the windows work, at least Here, here's one working, that one Is it working? Yes the one on the right is running slowly we would have mounted the spacer anyway, so that's good it's already on Let's do it in pieces and no more talk about it She looked nicer before Definitely Is this wheel arch really made that bad? Okay let's see below what we have The funds are not in bad shape All the beating was taken by the exhaust The original exhaust wasn't like that, right? Original up to here, here maybe there was something they took out Maybe there was a center muffler This is the exhaust coming out of the turbo This starts from the exhaust manifold, the wastegate is hidden above here that discharges and returns to the main exhaust here We used to saw these back then, to put them on the Uno Turbos, on those little turbo cars The gearbox is a real Porsche one With the dog-leg first gear, which engages backwards the suspension scheme is not bad for the time These then had, like all Porsches, the caliper that is only for the foot brake For the hand brake it has the shoes in here Can you make me 4 euros of LPG? Check out the carpenter screws here They should be arrested for doing this to her. I guess the owner of this car was cool to have a night out together I guess he was quite a guy Bad, bad Alright I think "Mourn the dead are bitter tears" So... Come on
Does the motor come out? How do we get to that one inside there? If it doesn't go, we make it go I mean look, it's done on purpose, see how well it goes Go It is original, "West Germany" There was still the Berlin Wall; "West Germany" okay Shall we measure it? 23 What a magical moment With this noise... I already had to go to the bathroom earlier... Unbelievable Good that is not rusty water Here he is, our Transaxle Since the cutter is not enough we have to go with the heavy maneuvers Vince Carter! Does anyone want to throw this one? Let's exhale the evil It's all clear here Lots of details, brackets and stirrups They make you realize that they messed up on it over and over again I see you are getting attached to this turbine However all the manifolds, turbine, intake all strange curves That is, like it was narrower They stuck it up Yes Now let's do this thing to get an idea, of how it all fits under the car See this is the exhaust I was telling you... Look at the wastegate how big it is compared to everything else And then this is the little tube that we removed that stood like this Look at that turn for the exhaust they made up at the time Hallucinating All jammed in, overcast, there was a buildup of temperatures Then the gases come out here and there's this curve like this throttling the turbo here It will have to be given a good revamping We removed the gas cylinder Let's see if she opens her eyes, if she wakes up Ah, here the surprises continue That's really the whole 90/2000's kit Mamma mia all the worst of the worst of the third millennium We also have angel eyes Ah, they are also yellow Poor car, what have you suffered...
True Good night, go to sleep I knew Davide even before last year's adventure With the previous season of "From the Barn to the Track" because I was following him We were also with the Golf, I think, at the second "Drive Experience Day" event. And it was already talked about last year, since we have a certain affinity on some points of view, about doing a project together And so the 924 Turbo came out Which we will try to transform in 924 "Furbo" (Sly) This project that we have undertaken with David, is something ambitious Not so much about numbers, because I believe that a beautiful car Is not just the one that has big numbers The car must be beautiful all round I want this car to be effective, performaning, current But at the same time the car must retain the charm and beauty that has always distinguished it You can put this on the Doblò, this crap Away with the manifold This sensor is marked BMW I have no idea how it got down here No, I'm too curious about this potentiometer I have to see what kind of car it is from PF01: this is from a Sierra Cosworth 2WD How did it end up here? We don't know This clutch is not even that old They probably also changed it for him shortly before abandoning it I'm like a charcuterie maker see? The turbo was spitting out some oil. When you have to make the crib, you need some peat... You have it Let's remove the thermostatic valve Look what aim... Even the water pump is still good
Ladies and Gentleman, our camshaft. This has been standing still for 1,000,000 years There is not a single drop of oil left And here is the camshaft It weighs as much as the flywheel And we pull it up Stop Habemus turbo The weld goes all the way to the nut The wrench practically no longer goes on it This will stay here forever The head has been rectified so many times That practically the valves are recessed At that time the gasoline was so crappy That the only way not to detonate turbocharged cars Was to keep the compressions very low This I think is around 7.5 maybe from original Let's say they did "a few" kilometers gross This is a bathtub, not an oil pan What's in it? It looks like potting soil They were changed because they are relatively new, I mean, for the age of the car the engine As ashtrays, they are perfect But look how tall they are Huge bands right... Like trucks' ones These bushings are also new There is the center bushing that is more worn than the others Here I see spots, these spots are the metal that crystallizes with casting It really changes its characteristic Most likely this crankshaft has fused and has been ground and although it has been ground, the surfacing of these stains, suggests that the metal of this shaft is no longer good So this shaft will always tend to flex in the middle part where it has melted So this guy had spent a lot of money to rebuild the engine And it was getting destroyed again Yes Plus he put LPG in it Since there is a strong suspicion that although it has been rectified and then straightened the shaft, it may have deformed again because at that point the metal is now crystallized and has changed its characteristics Let's go for a check, to see if the crankshaft has an off-center So, we removed all the bushings from the cylinder block we put only the first and the last one, so that the shaft rests only at the end we insert the drive shaft Let's take a millesimal dial indicator We go to position and rotate the shaft, which in theory should turn straight Or with maximum 0.5 cents, 1 cent run-out that is of ovalization and by turning this crankshaft we have the beauty Of almost 6 cents of ovalization Basically, we have to throw out this crankshaft Wait, let's drain it Do you see a man's disease? The Turbo Mozzarella I know guys, we have imagination The Holy Knifa The Holy Knifa decreed It's good as chocolate... it's chocolate
Nothing, this mozzarella thing got out of hand The car is disassembled, we are taking it to the body shop It took relatively little time to disassemble it The surprises were all in the engine, the crankshaft is screwed up The most difficult component to find, of course, we found it broken So it will be long and stormy as usual However, at least we are enjoying Vesuvius and the sea We tried to understand why this car has been handled so much There is fun to be had, in short 700 kg If Giuseppe sees any mice... He runs We have already taken out mices It is painted and not prepared underneath The paint is jumping with the finger Can be peeled off even better This one, if you give it a good wash, it strips half the car already automatically This one is replaced It is cut off here, here it is Because when it was welded some weld hole was left, it was not filled in Moisture has blown away all the exterior putty This is his original green of the car The famous bordeaux You see, here white comes out, not bordeaux, so this is also another car White, green, bordeaux... Like the "Frecce Tricolore" Oak Green metallic Oak green, at least we know what the color's name is And that is something good In my opinion, the best thing would be to test the colors We could find a different variation, but still green They glued it with silicone This pole is very nice, very original I have never seen it with the roof opening like that Or they gave a bump on the side Another one, because they hit here as well They changed the door, then the fenders the bumper as well I would go and put it back where it was She looked so pretty in there They probably took a beating there, and needed to change the door as well Looking for the door, they found the car And they also did the cosmetic upgrade This is C.S.I. Naples When we disassembled the engine of the 924 we didn't find any good premises Because with the crankshaft in that condition the engine, which will surely have been manipulated several times over the years, did not bode well for us Instead, strangely enough, the cylinders were still in excellent condition With just 1,2 cents between consumption and ovalization All surfaces have been checked, it has been washed, squared And with the intention of giving it some horsepower since these engines have always suffered from head gasket problems We are having special studs built and I opted for a head gasket with separate recessed rings Which we're also going to test now, to see if they fit Everything fits perfectly And this is already good news Now let's move on to the lower part where we need to pay special attention Since that crankshaft in that condition might also have caused some damage to the alignment Let's take the so-called caps that have been cleaned, brushed and checked We are going to tighten them in place Now we take our pole for the 924 "Furbo" and proceed to verify it With a centesimal tally pole The first thing we do is to check that the housings are within the range of the measurements specified by the manufacturer After that, we are going to check with the alignment pole if the meltdowns this engine has had in the past has not caused misalignments of the mounts All supports are within the expected tolerance And, theoretically, now the pole should slide through crossing all the supports without any kind of problem and without finding any obstacles Perfect Now that we know we have a monoblock in perfect condition we can also fantasize about an elaboration And since, in essence, we don't have a crankshaft Because the one that came out of here is in very bad condition we can't find anything around either new or used It is necessary to have a crankshaft built from scratch, and since we have to do it why not also increase the displacement a little bit if there is room To make the crankshaft and connecting rods, I decided to call on Scam Which I believe in Italy represents one of the excellences in this field To see if there is the necessary space to increase the displacement so for a larger stroke, we made a rough 3-D model Going from the original 84.4 mm to 90 mm Should bring us up to a displacement of 2,130 CC / 2,140 CC Obviously having a small printer we had to make a puzzle that fits together And this will be our crankshaft To do the simulation however, it turns now we have to see if it also turns with the piston and connecting rod We assemble the piston pin, the bushings are there.... Let's go and put them in the engine
It's gone There you go, it turns Obviously, given the increase in displacement and stroke, the piston comes out from the cylinder block, so new pistons will have to be made with a lower compression height, for this we will interface with CPS special pistons who will redo our pistons and we will go and establish all the new dimensions to make a complete stroker kit We want to increase a little bit the liveliness, the response of the engine and we do that not only by increasing that little bit of displacement, but also by going to raise the compression ratio I'd like to bring it up to around 9.2/9.3 I think I'm going to do it just for a vein 9.24 : 1 Right now we are scanning the original piston bowl So we can recalculate the volumes To redo it with the right volume but with the same conformation And we then transfer the data to CPS who will make the custom pistons for us With this tool, which is a lathe that we modified With an encoder and a little software We are going to simulate what the cam lift is With the tappet, here made with this 3-D piece and finished reading, we have this cam which is the same on both intake and exhaust It already has as standard a lift of 11.6 mm
so enough, I would say with a duration of 308 degrees So like if it already was a tuned cam Just because it was the same cam as the aspirated version Put on the turbo version, who knows why... I would leave it like this. A Porsche? More than a Porsche, it seems a Pork now.
The car is in quite ruined condition As can be seen Poorly done repairs, putty in quantity, you name it So it is a car that will have to be completely stripped to zero To begin straightening, reframing and then we will go on with the priming, to prepare for the final painting It will be made original throughout No esthetic processing changes will be made we are still talking about vintage quote-unquote cars so we should respect its originality as more as possible. At the front we are going to remove this piece here Because Silvio will have to mount the intercooler on it So it will be removed this part here, cut internally the lining And put the new one on, to accommodate the intercooler I've been doing bodywork for 40 years I do this profession out of passion, it was handed down from my father And I am passing it on to my son who works with me From father to son there has been passed on this passion This is a job we have been taught to love and appreciate This car falls apart as you touch it I think the main reason why I got into this work is car customization, putting something of your own into it in your vehicle For us, it is not simply four wheels rolling But it's kind of our way of expressing ourselves I think there is art in this work because anyway we put our hands in it and it's all our creations We are craftsmen, so the craftsman tries to build not to buy and replace Because everybody can do it (Strait Neapolitan dialect about window removal) Dad is a good teacher, he is closer to me in the body parts Because it's quite a complicated job Whereas instead he lets me walk more, in the parts where by now he already sees me as being more shrewd Then surely another little surprise will come out, both here and here However, here you go with the Flex grain 16 Being a car enthusiast, I already knew the show Through Silvio I got into this story, which I think is a pleasant thing Beyond the work We are very happy to have this experience to bring something of us and show a little bit what we can do in here The 944 intercooler I found it on eBay For only 95 pounds By a stroke of luck, I found on Ebay a seller who gave me the intercooler for 95 pounds and grille of the 944 Turbo thinking it was an easy operation to do believing there is some similarity, but I realized that it was not so And if it wasn't for Peppe, who took the situation head-on and came down hard on it today we wouldn't have mounted the intercooler Here, it's already gone And here is the intercooler with the pipe So Davide, this is the current situation I got both ET and spacer shims, I'll write it all down later As you can see with the current situation, we are quite on the limit even at the back Compared to the fender wire, we are almost there Considering that this, going down a little bit, will come out I would say make the new rims with the ET that results in From the ET printed on the rims by adding exactly the spacer Based on how we do the counting after to Marco Sarro We entrusted this pallet of vintage remnants of the 924 Marco, will you give us a good miracle? Sure guys, you can count on it. Go Davide, let's unwrap Connecting rods If this stuff is good as I think...
we're going to see some good ones How are they, how do they look? They look like they were made by God, to me. Number 217 I don't believe in this thing that 17 is bad luck I used to play ball with the number 17 so... Ah okay Wait, I have bad hair...
Mamma Mia Excellence Is the old there too? Sure and we have to compare everything Yes. Also because, if it doesn't look like the old one, I think we can do very little with it Here it is This should also be 1 kg lighter There is really no comparison really very high quality product We basically increased the stroke to increase the displacement a little bit And they recovered weight, apart from all the machining, Look here; The shaft is drilled into the crank pins To make it lighter, they tried to recover weight here as well you see flaking the cleavers, shaping with these branches Formula technologies, and we've got it on a 1980 Porsche 924 Connecting rods: the workmanship is really excellent that is, they stole weight everywhere Imagine the laughter if with all the simulations we did with the plastic one there... It's all wrong We put it in and it doesn't turn Okay, down slowly... slowly Let's do like karate chop Let's put the washers on Please That's it. It doesn't just turn... It does MORE!
Piston, original pin: 605 grams Tommy's CPS piston and pin: 470 grams Custom connecting rod: 615 grams Original connecting rod: 880 grams plus another odd kg and more on the shaft, is 3 kg less in rotation With this one, when you accelerate... You're on another planet Should be very ready, we hope so. I'm not used to all this smoothness and all this shine irresistible smoothness And this I think is the first 924 stroker they ever made going up and down, it goes there I would say yes I have no idea what to expect from this car We expect it to entertain us In the meantime, I also got on with the head work That required quite a bit of work First, it had all the spark plug threads deburred So we had these inserts made Other modification, this one was born with stem 9 valves And basically to recover some passage in the ducts we put shank 7 valves And we fit Delta Integrale guides in it Of course, nobody builds valves for this car, so we had them specially made by MR valves Note the difference in weight. And obviously the stem in the duct will take less section And more gas will pass through What a beauty Here we had these injector mounts made that screw into the cylinder head in place of the plastic ones that were there as original Bosch 1000 cc injectors Injectors get in...
Perfectly Too precisely After that, these four extensions have to be mounted And last but not least, let's see if you recognize this one from what car it comes from There isn't a car we make in which there isn't a piece of the Sierra Cosworth, it's everywhere now I called Alberto and said, "Alberto can you give me a Sierra flute?" "What are you going to do with it?" "You give me the Sierra flute and don't worry about it." And here is the 924 turbo electronic injection with Sierra Cosworth flute and Delta Integrale guides Perfect While we were waiting for the engine's components we moved forward with work on the transmission and gearbox So we procured a torsen differential And had this clutch made with sintered disc and sprocket guard So we should have grip for the clutch But still, with the presence of the cotter pin, still have some driveability The gearbox didn't come out bad, it's not really bad at all I don't see chipped teeth or burned out bearings, strange things I've been a little bit on the fence about whether or not to put in a slightly more modern gearbox however, the appeal of having this first dog-leg and not wanting to totally overhaul the car Because I want it to retain its charm I was simply taken to a gearbox overhaul, LSD and that's it. Just pure driving pleasure Will it hold up? It should hold Because another feature of this Turbo, that is one of the earliest ('79/'80) Is having the real Porsche gearbox Hoping the car has some performance and accelerates I also started to worry about the brake system Which is something that you like So what I did, starting with the original 924 spindle I mounted 318 x 28 discs which are the ones from the 996... Exactly, like yours or even the Carrera 4 Calipers: we took calipers from a BMW pack performance so 135i or 335i The discs are an original replacement I made the brackets in 3D with the printer to see the dimensions well Now the brackets will arrive in ergal and anodized, and then we will mount them underneath when everything is ready to assemble the car As you can see the original arms are not that great, they don't inspire much confidence No Since we would like this car to make curves, with you driving it I thought I'd give it a little reinforcement Let's rough it up Saint Gennaro did the miracle the Saint above the Camaldoli Son, we save cars from the barn and take them to the track Peppino Silvio Good morning She would already be perfect like this Post-apocalyptic oh it came back straight Let's say we did a good job The sides were crooked, putty all you want The youngster worked on it much more, my son, not me You can call it strength of teamwork What do you say Davide, how does it look? Look, I am not so much for matte blacks, however this would also look good on it Maybe a gold headband Eh yes They all look like new metal sheets, like when you order them they come to you like that. Mounted -- instead they are hers originals That's a black that is not really black "New metal sheet" black Correct Look, you already can get over it Obviously slowly Let's not overdo it very cool Let's say she is now entering the make-up room To us Quality Control I want mortadella and tanned olives in it Gentlemen, it's chocolate Let's check Mozzarella is good Well please thank you goodbye You see the "Oak green" It is more beautiful from the inside Yes She has the characteristic golden reflection Beautiful, however it resembles today's Porsche "Oak green", that's pretty much it Yes, yes, I think so...
GT3 Touring, that stuff there Nice Beautiful, beautiful Crazy to think that she was thrown among the animals Did you paint it well for me? If Davide goes like 120-130 km/h, isn't the paint coming off? It is guaranteed up to 140 km/h Okay Davide, don't drive faster than 140 km/h, but sideways though, 140 km/h sideways? Ah okay, 140 sideways is fine. We'll bring it to you Ok come on, it's time for her to come back... Under Vesuvius Yes, it's starting to get big Cherry cream How much do you put it at? 70 Newton/meter, as we were told by the Scam people who supplied us with the connecting rods Let's give the shaft a turn -- also consider that the wrench is short so it gives little leverage I would say it doesn't have much friction it's okay come on Despite the short wrench Before I go any further, I want to get a fairly accurate indication of when the piston is at top dead center And, just to be sure, I'm going to make it on this other side as well Here now we put all four pistons evenly in the middle to avoid that as we go down the head, if there is any valve open, it touches on it and we make some mess After that, we go and seal the engine with the head finally Let's pull the head off the mounts okay Now with the traditional torque wrench we are going to do a low force pre-tightening to get the head started to settle on the cylinder block and also to get those rings planted in the aluminum of the head Now we take the wrench and go to complete the tightening So, Davide, one of the problems that the 924 Turbo suffered was that it always overheated looking at the old water pump the passage is practically obstructed, because to make the pump here behind the belt fit they practically crushed it And all the passages were obstructed So what did I plan to do? I took another pump, emptied it so that only the casing remained And instead of the pump we put a nice electric water pump outside Which is also kind of the solution they used on the Carrera GTs Maybe just because they had this overheating problem And so this one here, running independently, should give us all the cooling we need The fake water pump cover is ready Pass me the rim of the Typhoon Also of the F12 Yes, it looks like it actually Of my late lamented Malaguti F12 that I will buy back sooner or later Let's put the bolt on him Now let's put the engine more or less at the phase point we're going to put it back with the mark we made earlier and put the timing belt on it And block, there you go And turn And it turns free And turns Do you remember that pulley that was there with this sensor that they had put on it posthumously To run LPG system? You can barely notice the difference look I had the pulley rebuilt all in CNC ergal Weighting zero grams Then I drew myself the bracket that will have to hold the sensor with 3-D... here it is Already ready, finished and welded, just to be sent for anodizing It will be a cleaner job The basis of a good electronic injection transformation is to have a correct RPM reading I mean, we weren't going to get very far with that junk We take our pulley and rest it here on the engine for a moment Okay and here we're going to accommodate the RPM sensor (true enthusiasts will recognize which car I took it from) We put in this graduated disk with which we are then going to adjust the cam timing With a very easy but functional system And we basically made a system to see the phase of the engine Now let's go and place this other little tool that I made, that we couldn't even use you couldn't use this one either I know, however I'm recycling to optimize the timing.. come on Let's do a couple of revs to check that everything is going as it should So let's see if you can find the zero that I put here, with what you see there Here I make a rev, two revs and stop where we should be in the same position... like there
Right? Yes El comparador de Sevilla El comparador de Sevilla -- I'm more interested in not leaving the exhaust valve very open at top dead center Here we say to start with a conservative set-up It's a little bit much. We have to anticipate a little bit the cam each notch is two degrees, so three notches I would give it And then we will leave the final verdict to the dyno we always stop at our zero point He went a little bit further down Like... Very little Half a degree? Yes, yes Perfect, come on How much is it? Before it was almost 2mm. Now it is 1mm. I would say it's okay to start. Although the cam is standard (it is the same as the aspirated versions), it has good crossing So better to keep it a little more low, then, if needed, we can always tune it I would say the initial timing is ready, we can dismantle the equipment So now we're going to conclude. Let's put the tappet cover on as well The tractor engine is ready It doesn't look like something that will be so mean Helpless engine Terrifying engine You like it? Yes now Silvio mounts you Let's go and put the engine on the stand at the same angle as on the car Otherwise, we can't realize the spaces and encumbrances Yes, pass me the FTS baby. I can have some extra space here for the manifolds by putting it with this thickness of 3 cm lower Because, as you can see, we are sacrificed Let's block Nice mess with this little space And yes, we could do something like this Then start doing a couple of 180 degrees Then we could put this one here Here, instead of a whole curve, we put this half curve and we go straight down inside here Another one like this here With this one here, we go to here. This one here, with another straight line, we can go there
Here we go, the third one could go this route and this one we throw over like this Of course then we do a little more curved and more pleasing to the eye It remains to figure out where to put the wastegate It would be nice to put it here Nice poultice, yes Oh yes, however this comes better with a full belly Okay Dinner time Look at that order Look at that Go ahead, curiosity hypes Scrap? Yes Look at that They look very good to me Do you like them? Very nice Previously the bench was unique okay So we split the sponge Okay Same thing also the backrest, we modified the sponge of it and all the upholstery so as to give it more restraint in the curves and whatnot When you sit down it goes in there... And you get stuck Okay Very, very nice, congratulations Let's open the rest, let's open the rest It's like unwrapping presents at Christmas here We have never made this joke in the entire history of the show... Ah no No come on, it's not the same Wasn't it a total disaster? Excuse me, how did you do that? The dashboard was rotten, it was ruined badly, it was all wavy So we had to rebuild the structure underneath, mill and remove all the rotten part rebuild everything And going to repaint recreating what was the original dashboard thus keeping all the original piece It is restored, this is a true conservative restoration of the components So congratulations What else do we have? Very cool In this case we lingered, not only on the leather part But also on the carpet, which was all ruined we repainted it and then gave the right color to the carpet It works This was the Porsche's back seat Was it like that? It was just like this This is the back seat Still the same reason You know, I would almost prefer sitting in the back than in the front A little bit of weight in the back can be useful A little bit more traction Truly outstanding work, wouldn't you say Davide? I would say yes We have earned a mozzarella Davide, here I have prepared everything that is injection system for this 924 I thought of making a system with two pumps, one first is a transfer pump That from the tank, passing through this metal filter goes to feed and fill this little 1.5-liter tank that is a nourice, an "always-full" Inside this there is a 400 liter/hour pump, so even going sideways Or on the track, it will always draw gasoline from this one here that will always be full And under slight pressure Then along the fuel line we will install a "Flex Fuel" sensor This basically goes to recognize the percentage of ethanol in the fuel And then the car will figure out by itself whether there is 95 octane, 100 octane or if someone, carelessly, also puts some additive in the tank From the electronic point of view, we install a DTA which are the electronics that I use this is the new generation, it is a T4 Plus its feature is to have an integrated Drive By Wire controller with electric throttle so this will be useful for cold starts, for starting, for idling because from this car I expect a great regularity of operation, besides a pleasure of driving The wiring is almost all ready, I have provided a little bit of all the sensors There is a little something left to put in, but it has to be installed in the car To see where we will then physically go to mount the coils and other components We do it all with braided tube made of Teflon so that we are sure that 30 years from now we will never have to put our hands on it again On the fuel system of this car Very good So Davide, here we have prepared another treat This is the original instrumentation of the car I didn't really like the fact that it had this full scale at 6,000 rpm so I bought, again on eBay, these two instruments, from the U.S. version We extended the scale to 8,500 rpm And the full scale of this one at 300 km/h The econometer we make it a Turbo gauge Then we also had the little instruments made, these additional ones here And here I had a dedication made for the show: "TC Engineering 924 - From the Barn to the Track" christened just so even though she was in a pigsty more than in a barn, however, that's okay The car came back from the body shop and there was nothing there. First, we restored the electrical system with an electrician friend, whom I thank Since these cars were famous for catching fire, I covered the whole bulkhead with this panel that is heat reflective And it's fiberglass and all the electrical system, all the gasoline system has been removed And it ends there, so basically on the turbo side there won't be a wire anymore there won't be a pipe, nothing That is, as we see it now Yes I also had replicas made of what were the stickers in the engine compartment However, I did allow myself some license like this one here of the gasoline said 98 octane minimum and I put 100 in it, as 98 is gone anyway "This 924 is equipped with an electronic ignition/injection system of DTA Fast by TC Engineering...
Therefore, it does not need any manual adjustment." there is also a quote to dear Alberto Tiso that "therefore" is his favorite word Yes, indeed it is And here we have the engine practically completed With everything to put in the car Branded cart Branded trolley made from the iron chunks that are always leftover around the workshop This is the electric throttle I was telling you about, we had to saw off the flange and change it with this one here CNC made The manifold remained the one we found on it Sierra flute fitted properly Alternator we overhauled it Water pump is gone So we also did the belt path going only on the alternator with our nice CNC pulley And then the exhaust manifold assembly, turbo and wastegate which came out almost the same as we had assumed to do it These cars also suffered from the problem of a spongy clutch pedal because this pipe would swell up So I made a nice braided hose, all braided And we shouldn't have any clutch engagement and disengagement problems either All right, so when is the time to put it in, now? Are you curious to hear how she sings? But look, if you are really curious, I can satisfy you right away I can start it right here Yes Let's go The Shaman Does anyone remember how to mount this? Let's start by connecting the four injectors Water temperature sensor the revs sensor below we also have the detonation sensor gasoline pressure sensor and oil temperature sensor So all parameters are logged in ECU I would say that the wiring on the engine dresses impeccably let's put the engine oil Give me this nice battery and we put it here Let's go and connect with a flying lead to the engine We're going to take this flying indicator lamp and we're going to connect it to the oil bulb so that it simulates us the oil pressure light engine, in fact see now it comes on After that we run the engine with the starter motor To charge the oil circuit Give me the ignition key Now that the oil has arrived and the engine is loaded, let's go put on the essential accessories In order to get the whole thing running This should go here Ok 1 and 2 You should have been at NASA, not Torre Del Greco What you don't do to win a bet Ok now 1 The moment of truth Water 24°, air 26°, oil 25° Our Doblò pedal works 100 octane for you doctor, I put here? Put there, put there, put there There is everything that can be dangerous in this moment put together Below Vesuvius volcano A nice makeshift electric pump Don't try this at home Don't try this at home It goes up In case we have to explode, it was good working with you Feel that idle, almost zero vibration Doesn't vibrate at all Accelerate a little, let me hear how this Turbo blows, come on What the f**k is this stuff Let's warm up the mozzarellas a bit because it's getting cooler (Neapolitan terms of excitement) Salt them like there's no tomorrow Father bless me, I have sinned Amen I have so much sin Bon appetite We are planning to find out whether the Vesuvius protoxide sprayed on fire is flammable or not, though Davide doesn't really agree Just do it toward your cars, for me you can do all the testing you want to do Away from my Doblò Let's do as much tests as you want Secret recipe: Aglianico di Montemarano 2019, Vesuvius protoxide... And we fly They are making the Subaru SV sketch Subaru SV with the NOS Hold it, we have to put it centered Let's start lowering it slowly Still I put the plate And the two nuts Ok now let's lower the car a bit and check that the two studs go in And we lock everything down Touched Perfect I start pulling the mounts on the bodywork Where do you stand? Here. Last night it was cooking arrosticini and now it fits in the car let's not waste time, traverse Go Davide, hold this one One below and one above Wait, I have it Sober colors Those that were available These ones we then use to see both a little camber and a little caster And thank goodness Because they are practically orientable We can put them in all positions except that it has to its original adjustment below of camber It is fine Go shove them under Push Davide, push Now I can push Let's say that the initial adjustments when they came in I made them a little fancy Come on up a bit we put the spindles on and I'm curious to see these calipers mounted Have you seen the gray of the Fiat Marea station wagon how well it goes with it? Last night's mutton, arrosticini Guys, we have to put a stop with these hard gastronomic sessions Some hammering okay go put the dice on it All right At the rear, this one carried torsion bars in the bridge old style 911 type We removed them, and made coaxial tight spring dampers so that we can, apart from varying the height, also play a little with the hardness To give it more or less traction behind This I give to you Raise it, I am tall Enough, enough Ok let's make all these cables disappear These go in here Nice and clean. And now: the nice touch From roast-blower, to tire-burner Nice, nice brakes, nice everything Now we also start to play a little bit with brake booster, brake master cylinder We'll put a little more generous brake master cylinder As soon as the rims arrive we'll also do some...
heights to start to get a feel for it So we get it out of here and mount the dashboard, upholstery, and go ahead Come on come on, the premises are all there By the way, I have never driven a 924, nor a 944, either original or tuned So this will be my first time Well, me neither A little more work and it goes on the road NTM Wheels - Made in Italy - Porsche 924 Turbo for Davide Cironi This is a real custom rim Beautiful, gorgeous I mean... united. I want to put it with the thread down So like this Yes I am positioned here Stop, leave it neutral That can be fine, come on In this show, as Davide said: we don't eat at all I put a bet, because this car has kind of haunted us on 4, 2 and 9 numbers Many things; for example, even when we found it that morning, it was 9:24 a.m. Really? So I would be happy if this continued, and it would be nice to get 429 horsepower out of it That would be 924 in reverse Indeed I put this bet with Davide, and basically, we only open the mozzarellas if we make at least 429 horsepower Listen, we have to do it, because I want the mozzarellas Yes whatever but at 428 hp we can't open them up Let's turn on the ignition Come on, start the engine Go start it up slowly, slowly That we start to see a little bit of the naturally aspirated part of the map We can do an N.A. launch to see how it goes The original is 170 hp We are 10 horsepower behind In naturally aspirated, though Not bad, not bad See, turbo pressure: 0 bar, because we disconnected the pop-off Temperatures are all okay. Come on, we can give some turbo Now let's go and remove the blockage that we put on the pop-off valve, which was holding it open for us And let's try with the minimum configuration which should do about 0.6 bar of pressure Which is the calibration we gave basic Shall we go? Go So Davide, the car with the N.A. map made 161 horsepower
As I told you, we installed a switch with 6 positions So we can choose 6 power steps final result of the minimum step we can do was 249 horsepower 315 newton/meter working with 0.6 bar of turbo Next step, with 1 bar we were able to make 294 horsepower (it seems on purpose but it is not so) 398 newton/meter of torque Next step, it's 1.25 bar and we already make 330 hp with 445 newton/meter of torque So already it becomes challenging Next step at 1.5 bar: we make 363 hp with 494 newton/meter of torque And this is the last launch we tried, at 1.8 bar the car makes 416 horsepower and we are basically at 592 newton/meter of torque We have to reach our goal, we are at 416 horsepower now so we are just a tad short Let's try these mozzarellas then come on let's see if we earn them Ok turn it off We earned this 4.29 kg of mozzarella cheese It seemed to suck in the whole intake tube Indeed At one point I said: "Now she pulls it into the manifold."
I was afraid it was going to burst, jump out for this you have to put a hood on top, the hood closes, if it blows the tube doesn't shoot it into orbit Especially you will never know what happens in there with the hood closed Because if you see it... Bravo, maybe if we see the hood bulging it's the pipe's fault This time not from a chicken coop, but from a pigsty From the worst clubs of the '90s, she had an LPG system neon, whatever demon object had been stuffed into this poor 924 Turbo But today is redemption for her with 429 horsepower It is redemption You can smell good carburation Look at it, look at it, look at it It is too beautiful Tough... She is a tough one She is the villain of this year, by now it is already sure, she is the villain of this year without any doubt here comes the crazy train This was the bonus curve Silvio, Silvio, what did you do? It's chocolate The steering is beautiful, although, as you have learned by now, of course every time we go to the track for the first time it's always everything to check, everything to review But it was born very, very well... very well The "Turbo Knifa" ! Super Knifa! And the power... the power and how it delivers, how it unloads! There is some work to be done on the suspensions behind because it came much more cambered than it should However, this helps it to go a little less sideways, given the 429 horsepower which is a lot, a lot, a lot! I don't know how many 924 Turbos in the world can boast that kind of power this one does And I have like the idea that for all the fans of the model it will be a bit of an example to follow as far as the mechanical preparation part is concerned We've tried to be pretty good about respecting the... Wow ...Originality, at least on the aesthetic side Clearly you know everything we did, so up to a point but...
When it gets into torque, it delivers in a beastly way.... beastly! I have known him for a while now.... in my opinion he has never had so much fun We are in Binetto, at the Autodromo del Levante. I didn't know it, it's the very first time But I hope not the last one, because it is very, very fast and it is suitable to test a car with this power She's not easy but the work is well done So she gives you a way to drive her properly But it is definitely not an easy car given the power it has, very challenging it's not really a car for novice drivers But for those familiar with a turbocharged, rear-wheel drive of this era And of this power, you're having the time of your life You can feel -- you can feel the commitment and the fact that it hasn't been left absolutely nothing to chance on this build Look how she smokes, look how she smokes....
What a crazy horse, or rather a crazy female horse However, she is balanced really well Nice What a car Looks like he's having fun, the youngblood It drives me crazy that she is beautiful And that apart from the NTM rims if you see her go by you can easily believe that it is a beautiful classic car But it's not exactly like that! Wonder! Amazing... Now Davide has to buy me new tires They had 8 km... 8 km! That is, finished So? This year's villain is her Miss Powerslide 2022 It is her, undoubtedly Feelings, opinions? It goes strong, and I had no great doubt about that I've never driven a 924 Turbo in my life, so it's a first you can call it Porsche like this, I don't know how it was standard, but like this... I don't know.
Porsche for all intents and purposes I think we will never find out No, after this no, after this I will never drive a normal 924 It's kind of like the Golf, I have never driven an original aspirated third series Golf, I don't know how it goes This one goes very very fast, and it's also nice in trim now, we know that there is always to modify, there is always to refine everything but it's a strong one it is a very good start Electronic management, maps, everything else, the ideas, the design? The first laps I did in map 3, then I tried 4 and 5 I skipped it directly to 6 The last few laps I did them all in map 6 and regretted it of not having done them from the beginning with map 6 because it is 100 times more fun You also have to discover it slowly, come on My theory is the same, but then in reality it is more easy almost to drive in map 6 Because it's more ready, more predictable even though it gives you a ton more power however, in corner exit, map 3 is more conservative so it takes a little longer Instead the sixth one makes you come out already nice and full And from the middle of the corner you already have the power to go sideways... In fact the first few laps I was trying to go sideways at the corner entry and come out already nice and crooked And I couldn't do it. With the sixth one I could As soon as I downshifted a gear... We need to check the brake balance because a little something needs to be revised As braking power, though, it reminds me a bit of the 996 Which in fact is a male braking, it's not really... it doesn't knock your teeth out but it has some braking power Yes, it's a little old school but it's right to be that way After all, it's the first steps I entrusted it to you that she had 8 km, so... Now it has 50 km, so...
All right And it's beautiful moreover So you approve it Absolutely yes Would you autograph it for me? All right, are you sure? Sure, go I don't know how to handle these things So I can resell it So it is worth less now It is worth at least 2,000 less now But I don't have to actually sell it... This also is true Beautiful, "Oak green" nailed it So good the "Oak green" Spot on After like 100 kg of mozzarella We finished And that's gone too, come on Silvio, my compliments Thank you And thank you Give me the marker back, thank you
