I was wondering what gears you guys are running with your Kenne Bell equipped GTs. With all that torque down low I was wondering if too high a gear is needed for daily street duty. I know on centrifugal blown motors it is all at top end. so a 3.73 or 4.10 gear is perfect. But an a roots style type I don't know if that much gear would cause very little traction due to the instant torque down low. I was wondering if the 9 psi kit is over kill for a daily driven stang-by the way my car is a 2000gt 5speed. 9psi or 6psi and what gears?
