All GT350 whipple kits are 10 psi by default and can be ran on 91+. It is not uncommon to run 10-11 on that type of fuel on that compression in a GT or 350. Then of course you can run better fuel for more power.
Not the case. You can run boost on boost a pump especially on a 350 with the fuel system it comes with stock once you add a boost a pump. BUT, for example, this cars fuel system is done. He came to check it out before we were going to have it delivered and decided he wanted a Fore fuel system which is the only way we can go more boost on E85. So next step on a car like this for more power is a Fore fuel system. Then once that is installed we can go more boost on E85. THANKS for the comment!
