I run 11PSI on 10:1 daily with water+alcohol injection (safety), though I've ran the same set up with out the water for a little while, but I wasn't beating on it.

what are you tunning with?

As long as you have a safe AFR and knock you can run as much boost as you want, until you max out you fuel system or octane fuel used.

it depends on the turbos boost capacity you can run any psi of boost on and compression ratio as long as the pistons are strong ive seen a 42r run 57 psi on 10.5:1 pistons
