Ive put 250hp to them on 15psi boost for 70K miles. I think 300hp is pushing it but mit might do it if you keep the RPM's down. I think to make 300hp the pistons will need to be changed to a lower compression ratio and forged or hyperkinect(sp?)

There were 2 of us that ran 250hp all day long for many miles, never a issue

Barrie @ Mid-night can tune the car.
