Again please provide the math. I think my estimates were all pretty reasonable and I end up at a pressure ratio of over 1.9. You can't just pull out boost numbers out of thin air. 15PSI in an efficient DOHC head (if I remember correctly, I assumed .97 volumetric efficiency, which is pretty conservative) of a 3.2 at 7000 rpm at sea level is going to make a hell of a lot more than 400hp.
