The Lingenfelter supercharger pulley upgrade kit is designed to enhance the ZR1 LS9 Corvette supercharged engine. This upgrade kit produces excellent horsepower and torque improvements over the factory 638 horsepower and 604 lbs ft of torque while maintaining a safe level of boost and supercharger RPM. Testing at Lingenfelter has shown 680 BHP and 660 lbs ft of torque with the Lingenfelter pulley upgrade kit installed. Installation of the kit does not require ECM programming or serpentine belt changes and will overdrive the supercharger 19% to raise boost on a stock engine 3-4 psi.
