I decided not to bother arguing this...since we DSMers know nothing about turbos.
BTW had a Mustang shop owner tell me that it was impossible to calculate the compression ratio of a turbo engine since it was dynamic and based on too many varibles. Oh and he said that a larger turbo always makes more power... Granted hes got some ponies down in the 9s (that Ive seen) and even high 8s (from what Ive been told) but this grasp of turbo theory was dismal at best...and he was talking to a group of V8 fans like he was Gods own turbo mechanic.
BTW the combo he is setting up is 9.5:1 with 21psi...sounds like a 23.7:1 CR to me...but what do DSMers know about forced induction?
