I'm, as usual, with Thermal. I'd fully expect a car with 11:1 compression on 13psi of boost to grenade the motor in pretty short order. If you're married to the idea of running 13psi, I'd knock the compression down to around 9:1 or 10:1 at the very highest with some damned good tuning. I'm pushing 12psi through 8.7:1 pistons...but the motor was built to handle up to 20psi and has seen as high as 18psi.
