LOL! 35psi KABOOM!
No, I've been reading about the lean issues at boost over 21. Lack of tuning options would nix that for now. But, look at the turbo Eurocharged car. They picked up 60 HP by eliminating parasitic drag from the SC. Their car had the same boost and flow as our SC but no drag on the crank. No low end power either. My thinking is underdrive the SC to bring it down to say 12psi thus increasing efficiency then using the STS style turbo to bring boost back up to 20psi. HP would be gained by less drag on the crank not more boost. The turbo output is plumbed right to the throttle body.
