Running through the gears wide open throttle on the turbocharged pitbike. Stay tuned for more videos, big plans ahead to make it even more absurd! 2WD hybrid electric #turbo
I have an SSR 140 TR that I’m currently putting on a VZ21 turbo. I made my own flanges and used the stock exhaust to run from the head back to the turbo and bought some 1.5” tubing for the exhust dump. I’m going to make my own bracket to clock my 26mm Nibbi carb correctly. I’m going to modify my oil cooler plate to run most of the oil into the cam and reduce the oil pressure coming out to feed the turbo safely and run the drain in the same spot you did. Is there anything else I should look for or do? I estimated it would make 6-7 psi. Do you know your Main pilot jet size and what needle clip you have it on. Also does it run fairly fine when cruising or partial throttle
Awesome! Sounds like you got a plan. I don't remember the jet #s / clip position, I did go a few steps rich, tuned based on the air fuel ratio gauge makes it easy. Targeting ~12.5:1 under WOT, a little rich. Too lean, too long, too bad! It runs great, smooth with no hiccups. Only thing I would suggest is to verify oil flow before plumbing it up. Restrict if too much, or you might get smoke. And make sure oil return line diameter > supply line diameter. Good luck!
carb before turbo, or 'draw through' has the advantage of being simpler. Carb after turbo, may have some advantages, but you need to seal the carburetor and have boost referenced fuel pressure to the carb.
@@dpdesignfab thanks for the answer. I will put the cvk carb after turb, and give the fuel a oil pump. May have many problem, but thanks for your sharing again.
@@qt808101 you don't necessarily need a pump, you could use the pressure from the turbo boost to pressurize the fuel, use a boost referenced fuel pressure regulator. The fuel pressure increase needs to be proportional to turbo boost, or at least regulated above the boost level, but there are other things to consider. Just think, normally (aspirated) where fuel is drawn into the carb from the venturi vacuum. Now if you are doing blowthrough, the carb is now under pressure, the pressure will find any way to leak out where the carb isn't sealed (or pressurized). The boost pressure would actually push the fuel in reverse, unless you correct the pressure differential.
It has a Nibbi 26mm carb, that comes with several extra jets. I don't remember the jet numbers off the top of my head but I think I went 2 stages richer, and it runs good, ~12.5:1 at WOT
