im running 9.6 compression stock internals. Ive got 11 lbs of supercharged boost. Im rebuilding another motor to put in my car. Im looking to put JE Flattop pistons with an 85mm + .007 bore, compression 10.8:1. Is this too much compression with 11 lbs of boost. If so I can JE Forged Dish with an 85 mm + .007 bore, compression 9.0:1.
