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