No quick answer without a lot more info.

Turbocharger or supercharger?
Intercooler?
Alloy or CI head?

I reckon you would be OK at 9.5:1 on that, but just a theory at the moment.

So 8.8:1 no problem.

i'm running 15psi on 8.7:1, lanning on a bit more once i've got a turbo that will sustain more than 15psi at the top end.
