A Chevrolet Corvette ZR1 with some modifications done by Lingenfelter recently ran a very impressive 10.03 @ 141 MPH at Muncie Dragway in Indiana. This ZR1 put down 739 HP and 720 ft-lbs of torque to the rear wheels on a DynoJet dyno. These are some stout numbers given the relatively mild list of modifications done to the car.
The modifications include a supercharger pulley change to increase boost, larger throttle body, modified intake and some changes to the supercharger’s cooling system to keep the temps down. Surprisingly, the car was running the stock manifold and exhaust system and no internal changes were done to the motor.
Running on a set of CCW wheels and Mickey Thompson ET Street Radials, the ZR1 was able to somewhat put the power down to ground during the launch with 60 foot times in the 1.6x range. Check out the pictures, dyno graph and video via the link below, you can actually see the car lift up the front left wheel a bit on the launch. If they only had some some headers and exhaust work, this ZR1 would have been the first to go well into the 9’s.
