Lingenfelter C6/ZR1 Corvette LS9 Supercharger Pulley Upgrade 19% Increase in HP

C6 Corvette ZR1 LS9 Supercharger Pulley

One of the latest additions to our C6/ZR1 Corvette aftermarket pulleys is the new ZR1 Supercharger Pulley by Lingenfelter. The Lingenfelter supercharger pulley upgrade kit is designed to enhance the new LS9 ZR1 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 supercharger pulley installed. Installation of the kit may require ECM programming. No serpentine belt change and will overdrive the supercharger 19% to raise boost on a stock engine 3 to 4 psi.
