My car is tuned for 8 psi but I know 11-12 psi is perfectly do-able.

I do agree with this completely. Every setup will produce different power levels at the same PSI. The power and torque produced breaks the engine....not the boost level.

Mine has stock internals and 160K with T3/T4 (57 trim) on 8lb spring (spikes to 9-10 psi). Its my daily driver and i beat the piss out of it when I drive it. It made 231 whp and 247 trq the last dyno run. My setup has been on the car for about a year now with no issues. I would honestly say I could crank it up to 12lbs with a boost controller and be fine.
