Yes. The compression does depend on the boost your running. The blower Im planning on buying comes with the pully that gives 6- 8lbs of boost. I can run either, but the 64cc will put me just barely over the final 12-1 ratio and the the 72cc's will put me a good bit less. Im more concerned with will my Gremmie run ok on the street with only 7.7-1 comp when Im not in boost? Remember, its about a 95% street car.
