Project Corvette

I removed the lower air dam for Eric when he bought the car, his driveway was stupid steep and would have destroyed it within a month. He probably tossed it. That should help lower temps too (in addition to the upper air shield from ECS).

Regarding the boost, if it makes 4psi right away in lower rpm range, it shouldn't taper at all. Normally centrifugal blowers make more and more boost all the way to redline. The restrictor should reduce the boost creep and keep it flat, but I wouldn't imagine the boost actually drops. Boost leak or belt slipping are the two most likely candidates, or possibly the crank pulley slipping on the crank if they didn't pin it again.

Good luck figuring it out and the speedo thing.

Edit: That's a fatass torque curve. How is driveability at slow speeds on city streets with the SC cam? Surge/buck at all with really low throttle?
