On my car the the 440's maxed out right at 15.5-16psi and I was running about 13.0 a/f ratios... and the rods crushed. If I had cast or hyper pistons and ran 19psi, I think the pistons defanatly would have cooked before the rods bent.
No bs here... I know what it like have a freak car turbo charged.. Shit I have a turbo saturn for crist sakes...I must be retarded or something.
