See Thru Engine on New Turbo Got Boost? (Nitromethane & Dyno)

Show Video

I'm already on Episode, six with this thing and that. Is, pretty unbelievable. Check out. I'm. Going to be picking up where I left off an episode, five because, this thing is just starting to make boost I think, the only thing that we are missing to make more boost is more fuel this is running nitromethane, not, gasoline which. Behaves a little bit differently in a turbocharged, application, so, yeah, let's see if we can make some boosts the only thing I want to change this, time around is the way that it's mounted we're, gonna just take a dolly some, two by fours a base, screw. That all together drill holes into, the concrete floor. And. I, think that's gonna work so I'm gonna be using gravity. As my fuel pump here to overcome, any boost, pressure, that we make during this run this is gonna be my regulation. Orifice, and it's, also going to be a good indicator, of how much boost pressure we're making because, as the boost pressure increases. The fuel flow in that little eyedropper there it is right there is going to slow down so we're all set we, have our nitro, coming, from the fuel tank like before we. Have our extra. Nitro using, it kind of like nitrous, with this valve I'm, gonna start it up on nitro through the carburetor give, it full throttle and, then I'm gonna open this valve right here just, like that and. Then we see the nitro start flowing it's already pouring out of the carburetor. Yeah. It's running I don't know how much power in me but uh I ran. I didn't hear the turbo spool though that run was very uneventful, not, really impressive, it made, four point five horsepower. On turbo, and nitromethane. About. The same as the previous episode. So I'm going to try it one more time see if we could get some more power out of it on this setup but. More importantly, I want to see if we can get some boost out of this turbo. All, right I heard, it starts. Bullying, and probably. Making boost and the, one thing that I forgot to do is install. A boost, gauge I mean how are we gonna see if it's, making boost if there's no a boost gauge. Let's. Run it again see what happens. That. Last run went, pretty, good the. Engine started, making. Some kind of knocking sound, and while. That may not be good and my. Opinion change is always good at least we made some type of progress here and it, made about, 4.4. Horsepower. Not. Really impressive, and the boost gauge was bouncing around just a little bit so, for this next run, I'm, gonna remove the exhaust manifold, completely, because, that is kind of a restriction and, my idea behind making this exhaust manifold, in the first place was. I thought, it would create kind of like a kind. Of flow in. There and. I. Don't know increase the performance but, it may have actually hurt the performance, so let's. Run it without the exhaust manifold, and see. What happens one, thing I want to do before this next run is just check the oil real, fast that's one. Thing I'm curious about. Whoa. What's. That that doesn't look good I, wonder. What that is. Doesn't. Really smell like nitromethane. It just smells like. -. Smells like oil I wonder. If maybe. The piston rings are broken or something I don't know I'm gonna change the oil, run. It again anyway and, yeah. That's. What I'm gonna do. Get. All that metal. All.

Right Cool. I. Heard. The turbo spool for sure that time let's. Look at the high-speed camera, and see if it made boost. I'm. Tired of this setup already I think. The real restriction, now is gonna be the carburetor like everybody said previously, in the comments I'm, gonna remove this carburetor completely. The whole thing, and that is the. Inside of our turbo, it's gonna be full throttle, all the, time and I'm, just gonna spray, the nitromethane. Into, the turbo, and, just kind of listen to it and kind of tune it as we go I mean, theoretically it, should work and yeah. Let's see if it actually works. All. Right ready, to go oh. Just. One more thing. My. Kill switch in case I need to shut this engine off in an, emergency or it runs away or something happens I'm, gonna get this ball and stick it right into the intake of the turbo cut. The air to the engine and yeah. Should, work right I. Got. It all in place it's ready to go my. Kill switch. Mechanical. Fuel injection system. And. Yeah we're ready let's see what happens this is a mechanical. I'm gonna call this mechanical, fuel injection, wide. Open throttle the, sky's the limit let's see what happens. Looks. Like that was the longest, run in, history. Of this. Engine, I've never seen this engine run that long and, it looks like it's overheating like hell but uh now. We know why they used a mechanical fuel injection and the Top Fuel dragsters because it's definitely. Reliable. For sure that, was definitely interesting, that it ran on my. Mechanical. Fuel, injection sprayer. System, what, I want to do now is I'm going to mount this exhaust manifold, back on here to, quiet this exhaust down so we can hear the turbo spooling, I love that sound, give. It one more shot the. Way it is right now and then we're gonna do something completely different. Alright. That was a pretty good run, yeah. I think that's all we got, whatever boost we got out of it right now that's, it I heard the turbo spooling that's, the most horsepower it's gonna make if it made boost and made boost and looking, at the high-speed footage I see it made about two pounds, of boost which. Isn't much but it did make boost can you imagine with that little turbo what this thing's gonna do I'm gonna go with a different setup altogether. But. This was fun so let's do the math real, quick once. I started applying more, load it started, eating up more nitromethane. And I just went with it so, if we do the math that's. Gonna be. 7.2. Horsepower. That's. What I'm talking about okay, I just refilled, this bottle, right now and on. That. Last run, they'd, used 45. Ounces. Of, nitromethane. That was like a two-minute run. 45. Ounces, I, thought. That was uh that. Was a pretty impressive number, for this next setup I'm going, to be using this turbo, right here which as far as I know is the, smallest turbo, that they make to give you an example of size difference, this turbo right here is 22, millimeter, and this. Is 27, millimeters now. That you saw what turbo I'm going to use time. For me to build it. I'm. All done with the new setup the, turbos mounted, the, intake pipe is mounted, and I'm just going to leave it without the carburetor, for now and do a quick test run, with, the stock head and do, what I did before spring. Nitromethane. Right into, the turbocharger. And see what it does first. Things first, before. You start any new engine, turbo. Make. Sure you add some oil. Alright, that was a test run with. The turbo properly, setup and the stock head and I, think it did pretty well looking. At the high-speed footage we can see it made a couple of pounds of boost and again it's freewheeling. There's no load I didn't, apply the dyno break. Did, you see that rpm I had to cut it short you. Know put that ball in there I didn't want it to run away but, ah yeah, I'm gonna do this run one, more time this time with the see-through head let's, see what happens. Alright, that was a pretty good run I think. We might have lost compression. Or something happened, cuz, it just died but uh yeah, that looked pretty good. Well. We cleaned that head up, alright, let's see what happened there why it's shut off that's.

What Happened, look. At that. Looks. Like our little screw, the, retaining, nut for. My electrode. Must. Have vibrated, loose I, don't. Know if it's the nitromethane. Or the RPM, or the heat or what I've. Never seen this before if you look at the seed through head and, it's. Actually, like polished. Wow. That's pretty cool if that electrode didn't break, off if that didn't happen I bet you we could just burn through this whole thing this time I'm going to run it one more time with the new see-through, head and I'm, just gonna, go. For gold I'm just going to try to blow this thing up and I. Have a wider shot on, the high-speed camera, hopefully, we're gonna see some carnage and something blow, I'm. Not sure but that's, the goal, to. Make a bull. Wow. That run was, probably, my favorite, run of all of them this, thing hit. 70. 400, rpm I didn't see what the boost was, because. I was so excited because this thing had. 7400, rpm with, the seat through had with. Boost so. I'm, gonna do another run this, time I'm gonna put the stock head on and my goals have. Changed just. A little this. Time my goal is going to be to, make as much boost and as much horsepower as, possible, with. The stock head I'm. Gonna give it as much nitromethane. To. Keep the mixture right. Where. I can here it should be and give. It as much resistance. On the dyno and let's, see what happens I think this is gonna be awesome. I. Don't. Know I got a bunch of stuff coming out of the intake of the turbo I don't I just. Don't think this turbo is as good but, yeah. I don't know I wasn't, really impressed let's look at the footage and see what it looked like. That. Run was just okay not. Really what I expected I. Wanted. To see more rpm, like that previous, run with the see-through head I can't figure that out I would have thought that with this stock head we would have had more efficiency, and just better. Hello. And it would have got more rpm, that didn't, happen I also, think, that this. Turbo, charger design is, not. As good as the Mercedes turbo charger the impeller, design is probably a little different because, with the larger turbo I can hear it's pooling more but, it was making less boost pressure and this turbo, once, it did start to make some boost pressure. Yeah, it just didn't I don't know it just didn't really perform, like I thought it was going to so, I'm gonna do one more run even though I don't want to I want to end this video here but I am determined to, make some booze pressure with this turbo I know it has, to make some boost pressure so, what I'm gonna do next is I'm gonna drill a hole into the intake, tube and use. That same sprayer always using run, a hose from the intake tube to the sprayer to, create a sort of mechanical. Fuel injection system. That, way we're injecting fuel after the, turbocharger. And not before my, gut feeling is that when I'm spraying the fuel into the turbocharger. Right. When it's starting to spool up the stream. Of fuel is hitting that compressor, wheel slowing. It down and, then interfering. With that, spool up so, I'm gonna try it one more time, with. This mechanical, fuel injection system, and let's, see what happens I have. A feeling. It's gonna work oh yeah. Wow, that sounded, good that, was good we. Did about three pounds of boost. 7.5. Foot-pounds. Of torque and about, 4200. Rpm and if I do the math real quick, that. Is about six horsepower, so it's not the most horsepower it's made but.

Yeah, I mean it did pretty good did, what I wanted it to do we, can move on I have, an AM P EFI. Engine management. System, then, I'm going to hook up to this engine for the next episode, I'm gonna try to do a full-out fuel. Injection, system, with all the sensors, and, that. Way we can control the boost the. Mixture, the, timing, the. Whole nine yards, that's. It so, see, you in the next episode, which is going to be this. Engine, and, hopefully. It's the last and then I said that like three times hopefully, this one's the last see, you guys next time let me know what you think in the comments below don't, forget to subscribe. That's. It see, ya adios. You.

Im laughing at the people saying this guy doesn't know what hes doing. He can build a Dyno from scratch, put this whole engine together, set all this up, get it working, stay alive, and he doesn't know what he's doing? I think that makes no sense

+Daniel Grampa Nah, there was a guy in my class at school who was an absolute maths and physics genius, A star every exam yet the dude could barely tie his shoes and was utterly useless at anything manual like carpentry, mechanics etc, intelligence can be very very specific sometimes. I've come across this a lot, my mum's old neighborhood was a nuclear physicist for a well known UK based company (not going to say which one) yet couldn't even drive a manual car.

some people are just jerks. some experiment to learn first hand and others learn from others instead of experiencing it first hand. if he came away from all these episodes and learnt nothing, then that would be bad

Warped Perception I'm stoked you're experimenting and sharing regardless on your limits or skills, thanks :) Try using the brake / adding load to see boost?

Jack Gorbachev I agree & I think he’s pretty smart but I wonder what happened to his middle finger ?

+MrcabooseVG lol, how badly was it done? what were the expectations?.

+zippyoya ha! I'd be up for any challenge you throw at me LBVS. Im a good actor but I don't think people are ever Happy. Imagine if I just said " hey I'm going to take this engine and put a turbo on it and it's going to run great, j show the build and then show one run where it runs great, end of video. How boring would that be ? Might as well turn on the elevator music and fall asleep. Not in my world, I like to have fun. Thanks for watching

Cuz he doesn’t

I could easily do that ..

​+Daniel Grampa I would start again if i did it that badly. My dad is a lawnmower mechanic for a living, i used to work for him and i could tear one of these brigs engines down and put it back together with my eyes closed, it'd be the turbo part i'd be in unknown waters with although i have worked on turbos but i've never done the whole thing from scratch. "i know enough to get me into trouble" comes to mind, sure if i had the money i'd be doing shit like this just for fun but i don't. I have a V-Twin 16hp mower engine i have been wanting to boost but forced induction isn't exactly cheap, certainly not when if i break anything i have no means to replace it

+MrcabooseVG I have to see it to believe it, can i see a video of you "doing that"? i would be equally impressed. IMO if your incredibly smart, then that intelligence applies to everything you do, not just one thing.

Im a good actor ! LOL

I could do that, i still don't know what i'm doing

Buy a fuel injektion Setup from a Predator Generator or a Peugeot Scooter and get IT running in that sucker

If you run it rich its going to bog down.

Why not just make a boost box for the carb? Leave your mechanical injection line in there but put a small orifice in it to limit fuel

Can we call this "How to ruin a turbo quick"

ADD NOS AFTER 20shot should work

how did he lose his finger

Can you please help me out in figuring the correct turbo size and the math involved for the setup for the KTM 390cc engine please!!!!!!

Waw god joob you pro

You're lucky the stock connecting rod didn't break yet.

If you can get a stoichiometric mixture of the fuels and air (maybe go a little lean so you dont flood out) using some sort of auto sprayer you might be able to eek out some additional power. But of course there are other variables ie not the correct amount of the nitro going in because it pools up at the bottom of the tube.

7.2 hp out of a 3 hp motor is absolutely insane!

That tripped me the fuck out for a second dude lol 5:09

The fuel injection he had would work if eh would put a varayble valve in the line

Is there any way I can get those 22 minutes of my life back?

Yes, just skip one toilet break, and if you're like me, you might even get a whole hour

Make a expanded exaust pipe off between the exhaust port and exaust port like a snow mobile with a turbo

Get a small turbo and your running it rich. You probably gonna blow a gasket because of the boost and the compression ratio.

(Runs turbo without oil) Hmm what's all this stuff coming out of the intake?

This is cool. I wonder if you try a hotter spark or maybe add more spark to the combustion so you get a solid burn?

Call me crazy. Would a 1 barel carburator from an old 4 cylinder engine work on this crazy set up. Like a small car or small truck. Since it will have less restriction due to is size. And at the same time be able to be adjustable and tunable. If needed you can add an electric pump made for carburators.

Spraying nitro around like it's not flammable or anything....

It's coolant

You would be better to run propane

Spraying fuel directly at a turbo thats not hooked up to an oil feed, or any turbo for that matter is a terrible idea. The fuel will clean off any oil you sprayed on prior to that.

Sick setup and love the choice of fuel. Gasoline is so boring.

Wonder if itll run smoothly if you used a water sprayer pump, kind used for spraying weeds in gardens flow isn't bad an pressure will be steady. Plus nozzle could be tuned for a fine mist which would be more controllable. Another idea for spraying into it would be machine a *throat* for the turbocharger inlet

Oh and see if you can use a finer nozzle for the fuel ... So it sprays a finer mist of fuel

This is really good stuff by the way ... Keep pushing the envelope bro!!

Why was there so much oil in it?

Hi good evening... What I've noticed, the same concept you did with the exhaust, to the outlet of the turbo. Make a cone for that, from the turbo outlet going into the motor in stead out eh blunt machined piece

you need a carb off a 10 hp engine or so bolt it to the turbo flange try and use regular fuel nitro meth has its own oxygen in the fuel so turbo not going to do much good just my 2 cents

Shouldve used a old Off bug spary bottle... Thats alot of fule in that little combustion chamber not enough fire i think.

Big a bigger engine that engine doesn't have enough to make boost, a 6.5 hp should be a better start or even bigger!

Love the slow motion

What is running away

4:53 the "flowie" thing you are describing i believe is called the Venturi effect, draws air away from turbo and out the exhaust resulting in more boost/power. Faster you can get air in and out of the engine the better it preforms. (Correct Me if I'm wrong)

Stop spraining fuel in your turbo your going to destroy it

So where's the ' see thru motor'

Have you put heavier valve springs in the motor. If not you may be haveing valve flot

thanks for the awesome video! very entertaining and has inspired me to use this same turbo on a 21hp briggs

Come on, man. Trying to use a turbo charger on a single cylinder engine just isn't practical. It's fighting itself. You don't have the exhaust gases to push the turbo to AT LEAST operation. You really need at least a 2 cylinder motor to even get any rpm's out of the turbo to even try to keep up with the intake ratio. That's why the boost pressure was all over the place on your gauge. First thing's first. Find out exactly how a 4 cycle engine works. When the valves are open and when they are closed. Exhaust spins turbo. Turbo forces air into intake. A single cylinder motor intake accepts forced air, but can't produce more exhaust for turbo spool-up. It simply can not. Exhaust valve is closed to ignite the incoming mixture on the power stroke. (Not to be confused with fords garbage). The next and final revolution of the piston is the exhaust stroke, but the vacuum created on the intake stroke has probably slowed the turbo down dramatically, and no exhaust pressure effectively makes it naturally aspirated, but it really isn't because the turbine is actually fighting the incoming air/fuel. In other words, the turbo is surging because it can not MECHANICALLY do what you're asking it to do. A 2 cylinder motor would definitely make boost. It wouldn't be much, but theoretically, if one cylinder opposes the other, you should get the exhaust gasses needed to turn the turbo.  Think about it.

guy sounds like urkle

Hey let me have ur brain

How in the fuck, do you lose your middle finger.

Dude.... just put the carb in front of the turbo..... make it a draw thru set-up

What you should do is not run it so rich and make a double Venturi exhaust manifold. It’s kinda like what you have now, but it’s more symmetrical which increases velocity and pressure. It’s basically what jet engines use, so if you did it on this motor I think it might help. I would put the turbo in the second squeeze point of the Venturi to maximize velocity and decrease pressure

Dm me so I can draw it out and explain better

You might be drowning the turbo, all that fluid on it will make it heavier and spin slower, figure out how to do port injection at the head.

For a Carb, use one off of a motorcycle. That is what the JR Dragsters use. I know this because I have a neighbor that builds the engines for his grandkids Jr. Dragsters. Jet it 4 points bigger than running on gas to start and work up or down from there as needed.

Check out those welds @ 4:49 !! What a great fabricator this guy is. He also apparently doesnt know how the fuel system is supposed to work...smh

Can't wait for the fuel injection

You need to have some kind of oil pressure flow over those turbo bearings that is not a ball bearing turbo and requires constant oil flow or the bearings themselves will drag on the turbo impeller shaft put a gear Drive pump in line to circulate oil through the bearings you will be impressed and much happier with your setup

Try some rubber dampers to reduce vibration? Some poly bushings ans/or stretchy ratchet straps may help? Freaking awesome man. Thanks for the videos. cheers!!

The reason the oil looked like that before you changed it is due to the by products of burning nitro methane. Among other things water is a large by product and through standard usage will make oil look milky like that. A similar thing happens if you run E85 through a standard gas engine for an extended period of time.

is that a glass head on the B&S engine??


You should have tried drilling a hole in the intake right before the intake port, pointing into the port as form of port injection. The engine would respond faster to fuel flow changes, the fuel flow could be more precisely controlled and it could make a bit more power. The only thing is that you need to be very careful with the fuel flow since there isn't nearly as much of a buffer to dampen changes in fuel flow. Even with the EFI setup now you should try to do port injection.

I'm pretty fuel you cannot Turbo charge Nitro methane with good results its been tried .. methanol yes

i just hope you have a good fire extinguisher.

You need to measure torque!!! Your rpm is limited with the flathead design.

You need a mister spray bottle not a squirt bottle.

run it with propane instead of nitro meth... propane loves turbos and is way easer to run

What is the Brand and the model of the smallest turbocharger used at first time?

To much fuel. Maybe mix it with some alcohol to take some of the % down. Also you need lots of spark to fire that fuel load.

Бля не могу это смотреть... Дай мотору раскрутиться шакал дурной! Начинает тормозным его давить чуть не с холостых... Ебанатик

Starts 22 minutes in...

-Makes 7hp from a 3hp engine -Sprays nitro methane around like it's water -Works in enclosed garage with running engine -missing a finger this is my type of channel. Subscribed and liked my friend!!

Why tf is he using a two stroke pipe lmao

Too much fuel. All he had to do is cut the fuel for a sec.

The irony of hearing "wonder what that is?" And noticing missing fingers. Not yourfirst rodeo. Try changing the temperature range of the spark plugs.

*pretends to do math on phone*

I love these inventions

what the story behind the missing finger?

Next use supercharge

Small motors, small gains. Noticed thos when i had my cr125 bored out to a 140. Just saying

Have you considered putting the carb in front of the turbo, i think thats how the beetle carb dudes do it, maintains suction for oxigen/fuel, instead of pushing in oxygen and by doing so fuel out?

Looks like your flooding the engine. Need to lean it out.

im so happy you finally put the fuel injection AFTER the turbocharger, that's what i've been screaming to myself the whole video lol. love theese see through engine vids, would love to see a turbo set up like this on the see through rotary.

We need more boost!

Heck yeah !!!

When exhaust was off it looked like the wastegate was wide open all the time. You will make more boost if you clamp that shut

I have no idea where you saw the wastegate open, it's clearly completely closed. Look very closely

i think also that you are getting bad fuel atomization. i think you should definatly get a carburetor of some sort. or get a smaller nozzle and spray the nirto at a higher pressure

if you manage to shorten the intake between the turbo and manifold. then it might not take so long to respond to the nitro-methane

What are you running that turbo on cause it isn’t hooked up the the exhaust

Or is the header you took off after the turbo

2 psi out of a 3hp engine and 7.2hp is really good that’s like 150% efficiency with the addition of a turbo


Idk i cant see you making more than 3 psi with that setup and thats if you get it just right Hey i was pretty close, that smaller snail should do a little better but i cant see it making a significant difference especially higher in the rev range

Needs a expation exhaust manifold

Well I realized after we finished filming this that the hole in the mounting hole in the turbo actually goes all the way through into the compressor housing, if you look closely when I am spraying the nitromethane into the turbo you can see it going in and coming right back out of that hole. I never seen that before and I'm assuming that's because it's a cheap Chinese turbo, but I will definitely plug-in next time.

That milky oil is usually coolant in the oil but as I can see this is an air cooled engine so idk why your oil was white lol

that is WAY too much fuel you need to get in more air

Judging by the colour of the oil the piston ring or cylinder wall is shot

You have to weld some restrictors on the exhaust of the turbo to make the housing smaller.

I love your videos and I’m going to donate, but under one condition. That you buy a FUNNEL! Lmao

LOL .... I have five funnels about 15 feet from where this engine is set up oh, but they were never used in the making of this film does that count?

pull off the pull start and do what Project Farm does, electric drill start

Yeah I tried but it was too much torque

Smaller turbo

Lol most accurate fuel consumption math I've ever seen. 44oz.....28 of witch ended up on/around the surrounding floor not burned. Great video for the curious!

I wish I could love your comment twice, very well stated

Dear sir (WP), I'm sure you have plenty of WW2 British spirit inside you: proper mad-cap back of a cigarette packet engineering, I love it! Could have done with a little more nitro, since the floor was still dry, and why bother with the screen? ;-) Full respect and I reckon you'll get over 10hp on street "gas" with efi... good luck and can't wait to see your results.

You need one of Cooper's Wet Shots.

great video, hooking up ms3pro ecu next is going to be crazy, will watch again.

I know that you proabbly don't want to do this, but the only way to make a decent amount of boost is going to be with a minimum of a v-twin engine. You would have much more luck with a little smog pump supercharger.

why don't you just hook it up to your air compresor and set the regulator to hvat ever psi you want to test???


”How to drain the oil . CrAnk the fucking engine without the oil stick . Fucking hell mate remove the damn oil plug

This guy only has 9 fingers ...

Make sure the waste gate is staying closed. I think that's your issue with not making much boost.

I wonder if this could help calculate how much boost per hp an engine of any size can really have I kno there's many variables that can come to play if I'm wrong lmk

+MrcabooseVG Looking forward to your next youtube video where you do this better.

+Bryan Roupe Okay? I wasn't bragging, i was making a point that i know what i'm doing with these engines. Everything in this is pretty simple stuff, doing it well on the other hand is something else

MrcabooseVG a monkey could tear a briggs down and put it back together with their eyes close. I can do a gov delete, cam, rod and valve spring swap from start to finish in less than a hour and have it running. Takes longer to scrape the old gaskets off.

+Will Crone I have a MK5 Golf TDI actually, tuned to 160bhp with a hybrid turbo. It is possible to have more than one hobby

+Arrested Lycian Development sorry buddy software and hardware are two completely different worlds. If you really don't think I know what I'm doing well just wait till the next episode. It wouldn't be entertaining any other way, do you find School super exciting?

+Ben Green  I always thought that was crazy, I met a quite a few mechanical engineers who don't know how to work on cars or some don't even know how to do brakes. I'm actually pretty well-rounded, my great-uncle was a nuclear physicist on the Manhattan project, my other uncle is a rocket scientist. I never really liked School much, I always like doing things hands, but like my grandmother always taught me, never let anyone know how smart you actually are, all you have to do is talk to somebody who knows me personally, eventually the audience will know me, but I'm pretty new to YouTube.

MrcabooseVG keep telling yourself that buddy your a 5 year old playing video games you don’t even have a car get out of here

+Warped Perception It's functional but look at the welds man, i'd bet there was blow through on the other side that would be restricting air flow too although i never actually saw inside so could be wrong. At a guess it sounds like it's running way too lean too

I can swim for hour and not die but it doesn't mean that i know how to swim efficiently. He just filling entire combustion chamber with fuel....

He has no idea or knowledge of how what he built is supposed to work. It's just like building a super computer and not understanding the software that runs it.

С ведра нужно было заливать

Ждал пока вся эта хуйня загорится

Cool vid, i think the nitro would work better in a cross engine though. theres a lot of fuel being recirculated unburnt in the bore.

Kick sss man you hope it's the last I dont I love watching these see through engine experiments

Possibly the most dangerous thing I've seen on YouTube with a Briggs & Stratton motor. I totally approve!!! (Kids, don't try this at home. Try it at your grandma's home!)

You should weld the waste gate shut and put a carby between the turbo and engine.

great video, some tech with some comedy thrown in. tip... as others have said, you won't get much if any running no load. try loading up the engine when it hits 3500rpm+ to see the boost. also, it is running way to rich as others have also said. you need to add less and try to atomize the fuel more by spraying it in at a higher pressure. good luck.

you are blowing it up

if this guy does this again. id like to see him un hook the waste gate


What show do these guys run on discovery? I can’t find it anywhere with spectrum

Use both turbos!

I was thinking about Putin a little turbo my my 110 quad what u think?

Awesome. I think you really need to work on your fuel delivery. Sometimes less is more. Find a way to inject (hint, hint) your fuel so it atomizes. Looking forward to the next video....

Turbo needs oil pressure. Run a Bosch VP44 pump off the engine drain plug. Rig a oil return. The turbo shaft floats hydrodynamically.

Am I missing something about the nitro... flashpoint is 95°f... hot exhaust manifold

You can see you flooding it out with the see threw head it's running way to hot need to reduce the fuel till you get the brightest flame with out killing it with more fuel

I love it! Great experiments! Like you i really want to hear that turbo FULL SPOOL! keep bringing us these cool videos brother

Should've called McFarland Tuning

Dude install anti-lag next

It will have it with the EMS

Too much fuel brother and yet you keep injecting more :/

The oil looked like that because there may have been moisture in the oil

You need actual oil pressure for a journal bearing turbo. This is why it won't spool well, friction yo.

The fuel just spraying on the hot exhaust and then the see thru head just sparking away. LOL you made my day dude. Buddy you had gas all over your arm. If that thing popped and made a flame out the exhaust while you were spraying,,,your next vid would be from the burn unit. There was fuel everywhere!

I was hoping and caught fire actually, imagine the whole engine on fire while it's running with the see-through head, all while being filmed in slow motion, that would be epic. If you thought that was bad check out where I was a week ago but I do have all the safety gear there, blast Shields fire extinguishers and all that good stuff. thank you for watching and thanks for your feedback I appreciate it.

What a ridiculous video

Rip turbo from lack of oil no oil even just a oil in the turbonis better than nothing burn up the bearing and seals And Mercedes turbo are more low pressure than high pressure just letting you know

What happened to your middle finger

Looks like a lot of fun. I would try port work, lot of compression, got cam and valve springs next. Should have built a 8hp or at least a 5hp. I have a 28hp briggs I build in shop class in high school. Still have it 10 years later.

You actually showed that running too rich the combustion is less efficient

I noticed that when you had the clear head on it it was misfiring I think a hotter coil and plug would help

Try a type of expansion chamber to reduce exhaust pulsation.

The turbo will never get dirty.

You need a longer exhaust and a better carb that properly mixes the fuel with the air . Also clean your piston , rings and spark plug , then do another take .

Your also drowning your engine

The mixture calculations, must be made over the amount of oxygen admitted in the cylinder (stoichiometric calculations ex. for gasoline is 14 grams of oxygen for each gram of gas), witch is difficult to calculate in this set up! But for sure that amount of nitro is way over...and for me, the engine was obviously choked! Next episode with the electronic controller, things must be different. Anyway thanks to show us it! Good luck! Let´s blow that thing!

Absolutely, nitromethane needs to run very rich compared to gas, even in a top fuel dragster, which those are my guys I know them personally, half of the nitro is burned in the cylinders and the other half or even more goes out the exhaust to produce the rest of the downforce that they need for the car. That's why they have huge flames coming out.

You can also use a shot of nitrous oxide to spool the turbo.

Main reason you're not making boost... The damn turbo is too big for that motor. You need about 5 times the exhaust volume to spin the impeller. For that size motor you need one of those little turbos you find on a keychain.

LOL! I like how the fuel served three purposes. To run the engine, to cool it and to shower any grime off of it. Just binged through all the series and can't wait for the next episode.

LMAO!!! , I love people like you that actually get it. I'm having fun with this thing for sure, it's a ton of work but I think in the next episode it's going to blow, since it's all going to be computer controlled I can use anti lag, rev limiting, extra timing, whatever I want it's going to be a blast.

i have seen peoples put carpurator oon in turbo in small engines but what ever peoples likes and you need to spray casoline in fine fumes not dropping that in like water hose more fine spray is more its can put air to in so its burn like its normaly do

the reason the oil gets yucky yellow is because of the methanol thats mixed in the nitro to get 50% slips by the piston rings... if u wanna burn higher % nitro u are gonna need more compression 1:15 .. dont forget that to mix nitro u have to weigh the fuels to get an accurate % .... if u light nitro with a lighter noting will happen..... because u need compression hit it with a hammer it will explode gotta love CH3NO2 greetings nice channel....

last replyy i want u to get 12hp outof that engine ... run atleast 47-55 degrees of timing 1:16 compression and make a fuel line with a jet in it and a secundair fuel line that goes back to the tank so everything the engine doesent except goed back to the tank... kina of mechanical injection

and dont forget cleaning everyhting that the methanol gets in contact with excpecialy aluminium thats why everyhtings anodized in dragracing for the methanol.....

It’ll be interesting to see what boost you make when you fix them two massive air leaks on the compressor housing lol :)

A better way to shut it off is to put a zip tie around the spark plug wire and pull it when you want to shut the engine off.

You should look up how people use Arduino computer system for $35 with a Vaper carb with an oversized regular carb with a OC sensor and have the flap adjusting it from the vaper carb to fresh air based on the OC sensor so it won't run too lean and overheat

Smog pump next then smog pump +turbo!!!!! The smog pump should make pooploads more low end torque and combined with the turbo should give it more top end. Also the smog pump should help the turbo spool! Can't wait to see it (if you do it). It's be an awesome minibike/go kart engine!!

you feed to rich fuel ass hole

Tiszta marha vagy!

A channel called build, break, repeat did a turbo gokart on their channel. They used the same turbo and got it to work great. They even dynoed it.

try spraying ether at the same time it works really well for a boost in power.

You are flooding the engine with fuel. Fuel vapors burn, the liquid fuel itself does not. Get an EFI kit instead of this cruel setup and you'll be seing some real performance gains :) Love the See Thru engine episodes tho ;)

This is surely a joke!!!!!

“Let’s start by turning the valve a little” opens it all the way

Que video bosta

Switch to race gas get it running correctly first then blend in nitro and adapt slowly as the mix gets closer to full nitro. I believe Turbos like e85 too.

damn that engine has seen better days.

Wtf un 2t de 50cc te da como 5hp

what happened to your finger?

Great job re-configuring the new turbo. Making good power now in both set ups. Before you end this series I was hoping you'd run it with Nitrous oxide. In theory you could reconfigure this back to gasoline (or keep nitro) remove the turbo and increase spray and fuel until the engine blew. Nitrous oxide is the great equalizer, the only limitation to power is part durability. You'd either end up with the highest HP rating yet, or a blown up engine guaranteed.

You had my curiosity, now you have my attention.

Your spark plug might have been one of your problems your electrode probably fires hotter the stock head you might have to figure out a hotter plug to put in it.

TRY SUPERCHARGED!!!! Maybe that gave more boost??????????????

I don't know what's the point , but I watched all 22.25 minutes of it PS by the way I subscribed

an you're flooding the shit out of the engine. its not making shit for power

the damn thing isnt going to run away. you quit giving it fuel its going to die

Flooding tf out of it no wonder he can't get spool

+Warped Perception If you still want to use the carburetor, you can try a "wet system", in this case the carburetor goes before the turbo and boost will not affect it, look it up, its used in some old turbo cars. Also i think a 110/125 cc chinese carb will be more tuneable and responsive for this purpose! just make sure you dont have any vacuum leaks!

Running it way too rich, drowning the engine thats why it wont stay on for long

Try doing supercharged and injection!

Oh wait he is gonna do injection... DO DIRECT INJECTION THEN

How am I just now realizing you don't have a right middle finger?!?!

smaller turbo

Just subscribed

Liked and subscribed

you should try nitrous

Do a vtwin 500-650cc, that tiny turbo, make some big soft copper head gaskets to lower compression, and use a big motorcycle carb for fuel. Use gasoline because you’re running super lean on nitro, you need a LOT of nitro fuel per amount of air and that engine really just can’t handle it. Also, put the carb BEFORE the turbo as a draw through, you don’t have to worry about boost pushing the fuel out


cant wait to see the full build

hah nice click bait

I wanna know what the name of the tracks you used are.

U gave it to much petrol


I guesd fueling is the biggest issue. sounds like you need a little efi setup!

u should run it with the karburator and just nozzle it up

use nitrous straight in the engine with nitro methane.

Put bigger carb take out limiter

Take out limiter

Just use arduino, old fuel injector and fuel pump from car. Ti is simple as fuck..... Current setup makes no sense.

why don t u use a electronic scale?!?!? so it doesn't wigle


You should also thread an AFR gauge into the exhaust manifold so you can see how much more or less fuel you need to put into the engine.


Weld the wastegate shut, it will make boost for sure then.

Wow over fueled much haha dont need that much for 49cc

It’s density not gravity

This is just stupid

You probably need more load on the crank to generate boost. You can rev an turbo engine to 10krpm and not make boost if there's no load on the engine...

Id put a little bigger turbo on it to get a bigger whistle. There will be lag but itll be worth it

whats the song name on 12:20?

that nitromethane is eating the crankcase seals thats why the oil look like it does

What type turbo Is?

Surely you could have gravity-fed the nitro-methane into the turbo?

When a gentleman with missing digits says "Don't try this at home" you should probably listen. I wonder if nitro would make a 2-stroke blower move more air?

What turbo is that?

My small 50cc engine has 5ps.

You might be use fuel injector and fuel pump ...

You should try pushing the boost through the carburetor. Instead of sucking fuel through the turbo. A turbo is made to compress air. You are pushing fluid .wich prevents the turbo from spooling. Fluid doesn't compress. In order to opfaun pressure with fluid there can be no air .Awesome work love it .

@warpedperception can you do a nitrous run with the engine


Why not make a separate proper oil system for the turbo? Put a electric pump a reservoir and a radiator, that turbo is dying without oil you could see it boiling the oil away!

Do a nitrous oxide episode
