from 6 psi to 10 psi under heavy throttle. The night I ran that car's best 15.30 quarter mile, it hit 11 psi and then emptied the cooling system through the exhaust. I replaced the headgasket and wastegate actuator, and had been running 6 psi ever since (until last week, when CKPaden let me try his rejected Abbott manual boost control valve...now I hit the 7 psi I wanted in the first place. Combined with the Intrax springs I just put in, this car flies with very little wheelspin or torque steer. I am tempted to try one more 1/4 mile...hopefully to achieve my goal of 14.9 in a C900. It feels that fast according to the ol' buttdyno...
