Forced Induction Compression Ratios

What about knock sensitivity on octane 93 (not talking E85 here), high compression ratio and super fast spooling twin turbos? I cant run 12 degrees of timing on even 8psi

I cant run 12 degrees of timing on even 8psi and go WOT with 3000 rpm or I'll run into timing retard issues with my stock compression ratio. Whilst modern cars can? A built engine wont change that right? But lowering compression will?
