I'd have no issue mounting whatever I could to get the most boost possible. In my opinion the motor can handle it.

The issues I'd forsee are high intake temps and the inefficiency of an SC12 meaning the last few psi give minimal benefit (get an intercooler), and the chance of melting/blowing up the SC12. But they are cheap and easy to replace and I think stories of their meltingness are exaggerated.

From the practical side I ran 11psi with an SC12 for years without issue and 16psi with an SC14 briefly without problem.
