I have a friend who has ruled the west coast 10.5 PSCA class, he defines the amount of boost as the amount of resistance to airflow His old Pro Charged motor ran with 35 lbs. of boost as well as with twin 88MM turbo, he swore his SB Ford heads flowed 430 + CFM at .700 lift He ran 6.87 at 195 MPH 5 years ago on those tires with that motor
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
