The engine does. Thats why they are rated. The block is rated to around 1000 and internals are variable depending on alot of things.

8-10-12 psi won't blow the motor. Its the power the extra air and fuel makes that blows motors, along with detonation. Thats why Brenspeed was more concerned with the torque number.

No, I was running 14:1 at one point that is very lean, 12-11:1 is optimal I believe.

Nice numbers! And don't be scared, I've been running 509whp since I was at 7,000 miles on the motor, I'm at 21,000 now. Just don't beat the **** out of the car and run a good tune from a reputable company and you'll be fine.
