Is there any smaller turbo available that can be used. I think the same power can be achieved with a smaller turbo thereby boost coming in early Also i would like to if it is intercooled or not
Pretty bad, I see it's only 7-8psi of boost. I'd make the plenum bigger and see what I could do to get the back pressure down. My drag 155cc made 50+whp at 22psi given it's a motor built for this. It's also pretty lean 14:1afr at 7-8psi. On pump gas we shoot for 11:1 afr. Now we're compound turbo and on e85 hoping to break the 100whp mark with 155cc. Wish we got the r15 in the USA so much better platform than what we have.
