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 back..lol

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??

Yes

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
