In this video we do everything that the kart would need in order to be driven for the first time. This includes making a boost capacitor, tuning in things like a rev limiter, and repainting the body with 2k clear. We got the idea from you guys about the boost capacitor and did some research and found an mit article about single cylinder turbocharging that shows the practicality of adding a capacitor to store air. After making that, we messed with the efi a little bit and added some fuel mapping and a rev limiter.
Thanks for watching and be sure to subscribe to see this thing drive!

Hi people what's up we're back with the turbo car and it is looking really good in the last episode. We basically mounted up this piece of plywood and put all essential items to run the EFI on it, and it worked out really good. An issue we realized is that, in order to make boost and truly tune this motor, we need to have load on the engine. We tried holding the brake and stuff, but it's just it's kind of sketchy.

We're ramping up the motor a lot we're sitting right here, like it's not ideal. So what we're thinking of doing is basically changing all of this up and mounting it finally doing a final installation on the turbo car. Let it self tune a little bit. I know something I don't really like.

The self tuning features that you code trance. We talked to John and Issac and cars and cameras, and they had no issues with it. So I think we're gon na get a baseline self tune and then we can do some data logging and adjust wherever we need in the curve. So that's what we're gon na do then we can put it all back on this.

Take you to carb fab and get it on the dyno buy. Some of you guys brought to our attention and MIT article about single single cylinder, turbo charging and most of the time, it's not practical at all, because you can't build enough boost pressure because there's only the turbo is only spooling when the exhaust valves open. So, in order to fix this people, add an air capacitor, which is like an air tank that stores boost, there's usually four point four times the displacement of the motor. So what we're gon na do is make one up, put it probably right about here or so, and then that way we'll be able to store boost.

And then, every time the intake stroke opens we're gon na have an equal amount of pressure going in each time or more if it's at a higher rpm. So this should really help us out. Let's get to fab, hey guys. Oh, I also forgot to mention I'm wearing our turbo JDM style.

212. Cart shirt. It's pretty cool Joe comes up with these designs on his own, pretty good artist so be sure to check them out. It's pretty cool that we're kind of ahead in the game.

We can wear this shirt of the car we're working on while we work on it. So if you want to be wearing the shirt of the car while you're watching you can go ahead and do that so thanks guys. Okay, guys, we are looking pretty good. So I just this flex hose is perfect.

Sighs just go straight down. I'm really glad. I was able to get this as compact as it is. There's not it's it's packaged very well, so this side is pretty much all done now.

What I got to do is I got a cap this and then run the runner from the throttle body to our capacitor. I hate hole, saws, there's a hole, some of our in our intro and I'm drilling the holes for the gauges in the CJ. It's like two hands holding on for dear life, so cross fingers. Some of this isn't turn into a decapitation device.

I'm not gon na try to touch that there. She is she's done yeah a little ugly. Oh I mean I don't know. I ran a yahoo, have tried to weld like galvanized exhaust it's hard to make it look really good, especially because it's just so thin.
So I might do a grind job over here and over here. This is kind of heinous. I used one of the trumpet go power sports like exhaust end tips, and I welded that to there. But I had to hammer in some of the edges and then I just kind of layered on welds who there are a lot of holes and stuff where the.

Where this melted don't really know what I'm gon na do there, I might exhaust wrap it, but as far as functionality goes, this is a really efficient capacitor and it's tucked up right up in here by the engine. So it's all it's really easy to install and it's gon na have a good airflow right up through here out, along with the bent ear, so air we around this corner. The only kind of bottleneck area might be right here because it's completely flat and doesn't have a taper to flow in, but I just don't have the metalworking tools to be able to do something like that make it look not like that. Alright.

So we just finished up, painting and mounting the capacitor. It looks really nice. It looks a lot prettier now that it's on here it kind of looked weird just all by itself, because it's kind of made to fit around everything, but we'll get all the wiring hooked up. And then we can start tuning this thing and getting it as close.

As possible before we ride it, ok, so we got everything hooked up. We got our laptop hooked up to the ECU everything's working. Alright at the beginning, we did have some trouble getting out running the fuel enrichment. Wasn't correct so on startup would be really hard to start and then after that it'd be you have too much fuel or something like that.

So we got we emailed eco Tron's got all that cleared up. It runs pretty well now so see if she starts. There's new little gas, so it's all warmed up and our rev limiter currently set at 6,000 rpm. I'm going to get rid of that right now should be safe, so yeah, it's got a burn this to the ECU progress.

Then your tuners, I'm a self-proclaimed but hey, we're trying also kind of a sneak peak. That's another little rotary motor km 48 and our plan is because it's a little bit less rare than a rotary cart. We're gon na kind of do a full, EFI kit and turbo on that too. So stay tuned for more rotary, turbo action and they're similar similar bass horsepower so I'll have to do a rotary turbo versus 212 turbo shootout.

So we just finished up all this bracketry juice and painted it for us, so how we ought to do. This should slide right into place and the reason we're actually going with this tape setup is because we need it, for we need to tap gravity feed to the pump. The pump doesn't have enough power to draw it up. So that's kind of a bummer with the kit, but we're gon na bolt it in and then we'll get on to movement.
Putting our body back on all right so now is all the wiring. The EFI is all done now. We need work on the body of this thing, so it's been sitting for a really long time. There's been tons of grinder dust oil spills, it's just been kind of abused and been tossed around a little bit.

So what we're gon na do right now is sand down the top clear coat, get all the grit and grime out of it, and then we'll pay with 2k clear, which would give it a really nice shine, and one small problem with our hydraulic brakes is that The body cannot fit completely on them, so what we're gon na do is just a little small hole Maxon all right, so we got the whole body wet sanded and everything prepared and we got to get clear ready to go on. There's a couple mistakes with it, but it should look really good with the chin. Pickler first coats, honestly super shiny, looks wet so now time for turn number two all right guys sing looks incredible. I get so shiny.

It really brought out all the I brought like all the colors if they're like mismatches or like different gradients, brought them all together. The light shines off of it. The same awesome result yeah and the difference between this and the rotor is we used a lot more paint on this. This has two coats that are really really thick, but I think, if you're looking for this kind of finish can't be stingy with the 2k yeah.

That's about a wrap for this video. This turned out amazing. We really love the 2k primer. So, basically, in this we went through our air capacitor.

We had got the tuning good. We kind of figured out that it was probably best to drive this thing. First, I let it self tune before we put it on the dyno. What we still have to do.

We have an alternator from an ATV that we need to throw on this, because the prior to 12 doesn't have any sort of charging system, so we're hopefully gear an alternator to where it's not going to take away too much power or anything like that and we'll Be able to get a charge out of this thing. We also want to throw a digital dash on this thing, so that's going to be incredible. Stay tuned for that de cocao. Stuff has really cool opportunities that allow us to use the digital dash, and things like that.

So thank you. Go power sports, a lot of the stuff from this cars from go power sports Stage; five engine build all of that stuff. Thank you guys so much for watching see you next time.

    Please tune this for e85r! Nitromethane would be amazing, but get used to rebuilding the engine after every couple hours of run time. I want to see someone make 25hp from a predator 212 without catastrophic failure…

  2. Avataaar/Circle Created with python_avatars cuestickbiz says:

    Ok so a air capacitor sounds like a good idea. But the way you made it sound is the turbo stops spinning because the exhaust valve is not open. Therefore not making any boost. Well we know from your other video it was making 8+ hp at the shaft. Keep up the videos though

  3. Avataaar/Circle Created with python_avatars Mitchell Chartrand says:

    What efi kit are you running? What programs are you using to tune? And is there any solution to the gas tank to where you could use a larger top tank instead of the smaller gravity fed? I have so many questions for you guys ๐Ÿ˜‚ love the videos. Inspired me to get started on my cart and im hoping to do somewhat the same setup

  4. Avataaar/Circle Created with python_avatars ifeel sic says:

    shouldnt be welding anything galvanized …take a dremel or smoething to it frist to get a better connection

  5. Avataaar/Circle Created with python_avatars Brenden Shore says:

    Idk if you do this or not but when prepping for welding you should sand down the metal for clean welds on the back and the front it will make them stronger And cleaner

  6. Avataaar/Circle Created with python_avatars John Fasano2 says:

    Bro "as far as functionallity goes" this is perfect, ummm didnt u just make it, its not hooked up how can u no its perfect dude???

  7. Avataaar/Circle Created with python_avatars Wayne Miller says:

    Two stage clear baby people think you can't get good paint jobs out of a spray can that is false if you get good automotive paint you can't go to AutoZone or anywhere like that and then also they have a two stage clear after you mix it it has 24 hours and you spray it right out of the can and it will last just as long as a factory paint job I do it the paint all of my brake calipers

  8. Avataaar/Circle Created with python_avatars Wayne Miller says:

    Why would they make a fuel pump that doesn't have enough power to draw it up and out of the tank why don't you just free tap the tank so the line feeds out the bottom

  9. Avataaar/Circle Created with python_avatars Wayne Miller says:

    did that rotary engine actually come out of the car I know rotary engines are a lot smaller than normal conventional engines but I don't know much about them all I know is that they can make a lot of power with a lot less weight but then you hear a lot of people talk crap about him about things failing a lot and then you have other people that only use them in their whole life that tells you how to get around those problems it's a headache

  10. Avataaar/Circle Created with python_avatars Wayne Miller says:

    I noticed a lot of blogs etc talking about these bolt on turbo charger kits and they don't understand that it's not as easy as it sounds bolt-on makes it sound like you bolted up and it's done except a lot of times you run into issues and you need to custom make parts for it because they don't sell them to actually get power that you want I guess you could bolt it on if you want to make 3 lb of boost and that's it but then you have to add more fuel as well so it's all about turning it as well you can't just bolt it up a lot of these people don't have any electronics hooked up to it it's just a small engine

  11. Avataaar/Circle Created with python_avatars Wayne Miller says:

    It's so crazy how these small engines can get a rev up to six, seven or even eight thousand RPM

  12. Avataaar/Circle Created with python_avatars Wayne Miller says:

    Now you don't see many small engines with an O2 sensor in the exhaust does that mean this has a computer on Ford that would be awesome cuz you could tune it that way as long as you have the right stuff electronically controlled how hard is it to install a O2 sensor and does that pretty much have to be done for a turbo installed or is it just recommended to help the engine run better I'm only asking because me and my son are about to start a project I have an old frame I don't know if we're going to cut it up and make her own thing yet watching cars and cameras that off-road truck is pretty cool that they built there's also another channel that build a Barbie jeep that is awesome but we might just find a way around to bulk up the suspension and put an engine on it but after the basic setup to get it to run he'll be a little older and I would like to teaching how to make more power and get into like a custom cart I am ase-certified in gas engines Small engines is just a smaller form of that and I've also taken classes in high performance so I would love to teach him these things that way if he gets into the field later he'll have a pretty good common knowledge and if he doesn't then he'll still have that knowledge my son is 8 years old he just turned this last May and he's just starting to get over the fear of dirt bikes and go-karts or four wheelers

  13. Avataaar/Circle Created with python_avatars Wayne Miller says:

    I wonder if they make a supercharger that's belt-driven or a procharger that's belt driven for small engines that would eliminate the exhaust valve problem it wouldn't matter if it had one or not then

  14. Avataaar/Circle Created with python_avatars Wayne Miller says:

    Or you could just mix your fuel with just a teensy-weensy little bit of nitrous oxide LOL or for that matter running on ethanol that'll give you more power

  15. Avataaar/Circle Created with python_avatars Wayne Miller says:

    Welds look pretty horrible but you can grind those down and make them look good enough I'm sure you haven't done that yet you're just showing us before you finish it all the way

  16. Avataaar/Circle Created with python_avatars Wayne Miller says:

    that one been to have in the air tank though is almost a 90-degree angle that might cause some problems because you weren't nice smooth curves for the air to flow around instead of it hitting a wall bouncing back and forth

  17. Avataaar/Circle Created with python_avatars Wayne Miller says:

    good thinking because there's only one exhaust Port so the turbo won't be spooling when it's sucking in there it will be spooling but not under power it'll just be residual spin left over from the last exhaust stroke you still gain boost but this way you should make more I would have a pressure release valve or something though that can work but I don't know how you would set that up without a computer controlling it but the way you have it with the smaller tube running out in the bigger coming in that means I can get all that are in there but then only sucks so much through that might work amazingly to hold more pressure in it for reserve or it might restrict the airflow going into the engine I guess we'll find out

  18. Avataaar/Circle Created with python_avatars Charles Southwick says:

    This is my first video I have watched and I need to know, is the light doorbell noise in all of them. Because of the issues I have with my hearing, the doorbell noise is very annoying and I canโ€™t watch them if that all have them.
    Sorry for the seemingly negative comment.

  19. Avataaar/Circle Created with python_avatars jason peizer says:

    Welding galvanized steel lets out some bad chems. You should ventilate and wear proper mask for it. You don't want leukemia or nerve damage.

  20. Avataaar/Circle Created with python_avatars Blaze-N says:

    Lol is it bad that out of instinct , when you started welding I turned my eyes away from the arc ๐Ÿ˜‚๐Ÿ˜‚

  21. Avataaar/Circle Created with python_avatars Dr Chan says:

    that motor don't look like a 212cc predator and turbos are shit – put a small supercharger on it
    and a small oxygen tank to force it into the engine or use nitrous oxide

  22. Avataaar/Circle Created with python_avatars Interesting Endeavors says:

    You do not need a boost capacitor to make boost on a single cylinder engine. It might smooth the boost a little. I have a Honda gxv390 on my mower making 6 pounds of boost on gate and running fine. Blow through carburetor.

  23. Avataaar/Circle Created with python_avatars M4D_MARK_XTr3Me says:

    Dude you really don't use top coat like that.
    You plastered that on, your supposed to layer it up and buff it between coats.

  24. Avataaar/Circle Created with python_avatars Andrew Mathers says:

    If your welding on galvanized steel drink milk to neutralize the fumes your inhaling that craps poisonous

  25. Avataaar/Circle Created with python_avatars rzor 93 says:

    You also should be using a respirator for that clear coat, those hardeners can get into your lungs through a dust mask.
