Maxing Out The Injector On The Turbo Go Kart! | Stage 5 Turbo Predator 212 Drive!
Вставка
- Опубліковано 13 лип 2019
- In this video we manually tune the turbo efi go kart and MAX OUT the injector. We were able to get it to run a little on the rich side at high rpm which is exactly what we wanted! This thing is really fast now and really builds boost and pulls into higher rpm. And we can really floor it and make the most of the turbo because before we couldn't pass 3/4 throttle. There is nothing quite like this and we are way past the point of this being practical so keep in mind this is only for the fun and experience of having a turbo go kart, not to make crazy power.
Be sure to stay tuned for this thing to hit the dyno!

Guys! Please put a torque converter on that and drop the rear sprocket size a few teeth. Then you can tune your engine to run at a set rpm and the clutch will do the work.
Add in an intake pipe to the turbo since the compressor housing isn't facing forward, you can get more air in and spool the turbo faster and get more boost
getting more boost is useless without having the fuel to keep up with it.
Don't forget to add heavier valve springs, hone the intake/exhaust valves, lighter flywheel/piston, and remove the governor! Your turbo will actually do something then....
Don't forget the pulse pump and a jetting replacement and/or adjustment!
@@jamesmcgee9279 jetting adjustment? This is fuel injected.
@@jamesmcgee9279 jetting? What freak turbos a carbureted engine
He made doing that tune look easy as hell, lol.. At first it was sputtering and did not sound happy at all. I'm a little surprised he got it that smooth for having literally nothing but a laptop... good stuff guys!
That stoppie turn was wicked.
An congrats an the shiny wall aft from yt.
Keep the builds going.
Love peace and axle grease brothers
Nice job boys.Congrats on 100K subs...
Congratulations guys, awesome job
Love you guys content , keep up the xlnt work all the way from Los Angeles 👌👍💯
love your channel, love your videos, karts, that c10, you guys are amazing! God bless :)
Congrats on the milestone guys.
You guys are doing some great stuff with the EFI kit. Tunning a turbo single cylinder is no easy work. If you ever need a mount for that tablet I own my own 3d modeling and 3d printing company. Id love to help you guys out for free
I,don't know why you guys are running a centrifugal clutch and not a torque converter sent up which would work a lot better for boost and low mid and top end
Congrats on the Tube of you's milestone.
107K... congrats guys :) well deserved
Congrats on 100000 subscribers!
Congratulations, keep making great videos.
Gear it TALLER, and add a TORQUE CONVERTER!
Gear it lower for more speed
@@ShutErDownBud gearing it "lower" is more low end. Gearing it higher/taller is for top speed.
Easy to remember gear terminology.
The taller guy can run faster.
So hes got a 2:1 diff.
The short guy has a 4:1 diff😂
ua-cam.com/video/kYw6ro-KjZg/v-deo.html
AimlessMoto They also should make a turbo intake, right now it’s sucking air from behind.
Congratz on the 100K...love your vid's
I hope you found the Bluetooth thingamajig that went awol on ya!?!
Anywho, I hope you have a great day & be safe.
You guys did a great job. Awesome.
That voice break tho at 2:42 , great video guys
Congratulations guys !You've earned it.30 mins,almost 500 views,again ! Best wishes for your future's too.
Think you need a flat belly and some skirts for that full lotus type 79 ground effect. I know itll do nothing at thth speed, but itd look cool
Flat bellies and skirts sounds like you are flirting with the dudes.
What an awesome creation
I like the Indy car style go-kart , i seen one on FB marketplace local to me for , I believe $300 wish I could get it but I have too many things going on right now , good video keep up the good work and I want your C10 truck ...lol and Congratulations on the 100k subs .
epic love the plack i hope to get one one day and the kart is sounding real good
That looks so much fun.
It's not CVT drive right? that's why it's such a dog down on the torque
those shoe clutches suck for take off and low end
Need a torque converter
Seems like it can pull way more gear too.
needs to make it a 5 speed
I cant wait for the turbo rotary!
Now that y'all have a tablet and Bluetooth and stuff, ya know what should be next? A ROCKIN' STEREO! I would love to see you guys do that! Please? Great job on 100K, I know y'all work real hard out in the Texas heat(since I work in it as well), so I'm ALWAYS cheerin' y'all on!
Also: Go A&M!
Id really like to learn how to gear these engines so that they could have progressive gearing. Great video series, loved the build, and ofc the test 🔥
That kart and turbo needs a 150cc or 200cc shifter engine, much better for tune and get power!
@007 T-5 a 4 Stroke engine!!!
@007 T-5. Sure you can
ua-cam.com/video/kYw6ro-KjZg/v-deo.html
@007 T-5 detroit diesels are turbocharged 2 strokes 🙂
What are you talking about. 2 stroke or 4 stroke. This engine on a shifter trans would rip. An most shifter karts are 2 stroked if not a torque thumper motor.
As a kid, we ran super modified dirt track car fuel in an 8hp Briggs motor. Backfire blew carburetor loose. We kept wrenches when riding. Straight pipe muffler it blew blue flames when backfire.
It was mounted on a reinforced 2 1/2 hp mini bike frame! It was super fast until we blew engine some time later.
Congrats on 100k! Just thinking...if running the engine hard standing still like that, maybe get a big blower fan to help with the air cooling?
2:42 love it! :D
Awesome job guys keep up the good work. Glad to see UA-cam supporters supporting their favorite channel. Always like comment and sub if you like videos.
Needs some gears 😓
Nice awesome upload !
Whats the top speed for this build ?
Why are you guys running a rev limiter? With a stage 4 build you should be able to turn 10k RPM no sweat. I've seen people turn 12 before failure.
David Hoskins the boost will make the Intake valve float worse since the pressure is trying to push the valve open
@@Archermboi On a stage 4 build I'd figure you would be running at least a 26lb spring?
If that's not enough I have seen 32lb'ers as well as double spring sets 48lb on eBay for under $30. I'd also recommend a set of chromoly push rods and titanium retainers while you are at it. The whole thing shouldn't cost more than $75 or so.
@@Archermboi the weakest spring you can get with a stage 4 is 37lb.
Every Pound of boost is one pound trying to push the intake valve open. I’m not sure if the valves are floating or not
@@Archermboi I'm sure that thing is only making 3 - 4lbs boost. The valves aren't floating.. The stage 4 kit is designed to turn 10,000rpm. They need to lose the turbo. Thats a 20hp kit and a cam with a lot of overlap. Turbos hate overlap and that turbo is way too big for that motor. The tiny bit of boost it is making is getting blown out the exhaust because of the overlap. The other thing about a lot of overlap is you need to rev the shit out of the motor to get any gains. This is a perfect example of buying a lot of expensive parts that don't well together. They have a cam designed for a normally asperated high rpm motor and a turbo that needs about a 1000cc motor to spool properly. Springs are the last of their issues
You guys got to put that set up on a 420 or 670
Love your Guy's Work! Do you know any History about that Frame? Have the same one that I am restoring and it has the exact steering wheel.
I like what you've done with this cart thus far. If you want it to go faster I suggest switching up the gear ratio between your centrifugal clutch and the sprocket on your rear wheel. Smaller sprocket on rear wheel, larger sprocket on clutch. Another thing you could try is incorporating a 5 or 6 speed Harley Davidson or similar motorcycle transmission between the clutch and the rear axle.
what do you guys think about a tuner piper before the turbo to help with exhaust velocity pulling pulses out of the engine?
2:42 That voice crack tho 🤣
Hey does the vacuum control have anything to do with boost on that one i know on my audi if its not getting vacuum to it the blades wont move and produce bottom end boost. Just a question
When your wheel is spinning at high RPMs it almost looks like your chain is on some kind of a square driving gear LOL I had to take a second look
Not to be an old man; but to be an old man I got a little puckered up when you flew by that tailgate at head level. If your engine locks up at a bad time you could be in a world of hurt.
Getting there, So basically now its a bigger injector some more tuning/adjusting of your map to fix your drive ability issue.
Maybe suggest taking to a wheel/hub dyno and not engine dyno so you can tune with load and have your AFR's etc checked.
Keep up good work, and wouldn't mind a $$ figure at end just to give people idea (good advertising option too)
After all that, a centrifugal clutch? Maybe due to space constraints. Still a sweet go kart!
It would be interesting to see someone with a Dyno for these things just do a big bang and go all out with like I don't know something smaller than a gt35
During the next Dyno session, PLEASE do a n/a run
That from the bird corporation? I just got a Sunoco one 💪🏼
I like the opening theme to the video much more "Uppity" if ya will.
I think you guys ought to fabricate a water-brake one of these days. Seems like something you could figure out. (Perhaps less complicated than the engine work.) Then you could load test the engine without burning up any brake discs. Could probably make something that bolts to the drive line, or perhaps a chain drive so it'd be simple to setup. (Not having to fabricate the other stuff for a full dyno or whatever.)
i think the real question is, does it actually boost or does it sit at wastegate pressure the whole time
It would be cool to see a dashboard molded out of fiberglass behind the steering wheel so you could permanently mount the tablet. Then you could have a digital speedometer.
where did yall get the turbo from im looking to boost a 600cc motorcylce
the top bolt hole on the intake of the turbo bleeds boost if there is no bolt in it
So what were the final numbers, HP, Torque, etc? Did I miss them somewhere?
Hmm... it doesn't seem like the turbo is hitting full spool. You may be getting positive pressure, but I'm not hearing any blowoff noise so its definitely not hitting whatever you set the valve to.
I wonder if supercharging might be better at this engine size... do you think that turbo would work on say... the ninja250? (I've been thinking about trying a tiny turbo on mine)
Faltou colocar borrachas nas laterais de dentro do cockpit, pra não se cortar ao sair do carro.
It'd be nice to see it compared to another Predator...
For real y'all should take it to the Dallas go kart track and run the old Indy car and the rotary kart!!!! I bet GPS would rent the track time.. 😋
You guys need a camera Gyro. So you can have those cool action shots!
If you ever return to this crazy cart, just tune ignition timing at low RPM to gain some torque at bottom end (timing table used in this video is good for top end because you need less advanced timing at top end, but at bottom you need advance the timing for best power) but beware of knock! 😂 Just experiment with it, you should hear knock at this small engine. Allso tune it for at least 13.5:1 AFR (= more power, because excess fuel will cool down cylinder walls and prevent konck) and keep eyes on intake air temperature....
I must say I really love that rev limiter when you hit it on road 😍
Pop off😆
Who's 5.br0 is that👌
Should use canam 450 efi as a base engine to work with
Where do you find the turbo kit ?
So whats the top end speed compared to a non boosted engine? Cant be hard to download a gps app and give us some numbers other than " its way fast"

Guys
it's pretty familiar from Boosted Boiz Turbo kart where they used to 31/2 in charge pipe it's seem to boost better ... work better !
You can make a home made dyno for small engines out of a brake, scales and some steel
i dont know a lot about turbos... just owned some turboed nissans and right away i thought that turbo is way too big for that motor 😁
It be cool to see someone build a transmission for a 212
I'm working on it. I'm working on a new smaller case to fit closer to Honda's n clone engines. When i get done with this revision I'm going to post some video.
Y'all need a Torque Converter.
Could you please make more videos of the turbo go kart
Where do you get the turbo from
You know. Well damn. Not to mock the truth or you guys. But why is it I’m not saying to myself”damn that thing is fast”!!
I get the feeling this was a fun project to get views and not a serious build.
Ya know what this needs?
A wing. A huge wing.
You guys gotta get a cvt on that thing, low end bog is awful. Other than that, it's AWESOME.
Richard Roper Yeah we’ll see if we can get it to fit, problem is that the way the engine goes it’s hard to put the torque converter on backwards
@@BuildBreakRepeat oh, that would be a problem, for sure. Think a wider axle could solve the issue?
would love to see you guys with the kyle from boosted boyz
Turbo karts race
Fucking love it Dart Kart
Add a 2nd identical injector and wire them together. Cut your map values in half to get started on the tuning process, and then add your fuel in the top end. It's simple guys come on
If you guys want I can try and tune the kart for you that way you have a good enough tune in the software so the self tuning will have little to to change.
Definitely think yall need to have an exhaust pipe on the turbo. It's not going run right without some kind of back pressure. Hell even just a pipe with no muffler would do the trick.
Hahahaha. That’s funny. You need to watch engineering explained. “Stop telling my engine needs back pressure “
So tuning is mainly just adjusting the fuel and air ratios ?
Air to fuel, timing, and a bunch of other stuff. Check out some of Jeremy and Cleetus's videos when they tune cars.
how much boost are you getting?
Put a ls injector with e85. Thats what the guys from nugget garage in AU did.
I tell you if you can somehow get something like a dyno did you can put the go-kart on actually drive it weren't acting up and kind of fine tune it it probably wouldn't take as long
good job, and i understand your build reason, but the chassis and framework seems to big and heavy weight for geting performance. i would say lighten it up weight wise, if not pull the turbo assembled motor off and mount on smaller lighter frame. the clutch springs sound to soft, put higher rpm tighter clutch springs in and raise your idle speed. also a higher octane race fuel like 98 octane or higher will help. rev limiter on because you dont wont to blow the motor, but your reaching for more power. gonna be hard to risk it, after all the work. a small cvt would help, but funding, space on chassis, room to build, and the added weight of cvt may only help a little. ideally for this weight and small cc engine, if possible use a old semi auto transmission 3 speed off a old honda monkey trailbike or small atv. 6 speed from a shifter kart 2 stroke is way to heavy and your motor wont turn it like a 30 hp 125 2stroke. but the cool factor of a turbo 4stroke gokart is awesome.
That seems.down on power,speed etc for a naturally aspirated engine at that stage build.
Plug the bolt holes in the turbo inlet they leak boost
I don't get it. So they couldn't take the chain off?
What is the max boost
Does it even make boost?
Sorry guys, but 0 boost means NO boost... you havent got enough exhaust pressure to build boost on that tiny engine... you wouldnt be making more power top end, that where the engine curve is least likely to make power.. keep trying, bigger motor i say.
They've got a huge overlap on that cam. All the boost is going right through.
Should do an intercooler pipe like the boosted boiz and then hook up a boost Guage to that!
Stop it with these suggestions that take absolutely no thought. They already have an expansion chamber. Why would they design it exactly like Kyles? They just need to keep playing around with it until they get it to where they want it.
Engine is not big enough to make turbo work. It's science.
cool bit of kit but ive got to ask, why a wind back and go. here in the uk we put manuals in every build regardless of what its going to be. but across the pond you guys tinker with auto's. but why🤔
Because we are pussies
Did I see the waste gate is open?
Big injector and e85 and more boost or deck the head .010
Id imagine with a stage 5 build im guessing around 30 horsepower 40 foot pounds of torque?
