Maxing Out The Injector On The Turbo Go Kart! | Stage 5 Turbo Predator 212 Drive!

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

@carlstone5735 5 жыл бұрын

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.

@buildingracingvideos4714 4 жыл бұрын

@@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

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.

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 😍

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.
