The Lingenfelter supercharger pulley upgrade kit is designed to enhance the new LS9 Corvette 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 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.

The Lingenfelter ZR1 supercharger overdrive harmonic balancer upgrade kit is designed to enhance the new 2009 LS9 Corvette ZR1 supercharged engine. The LPE overdrive harmonic balancer kit produces excellent horsepower and torque improvements over the factory 638 horsepower & 604 lbs ft of torque while maintaining a safe level of boost & supercharger RPM.
This harmonic balancer kit will increase boost by raising the RPM of your supercharger by overdriving it from the harmonic balancer. This kit does not replace the driven supercharger pulley on the supercharger snout.
Tuning is not required if the LPE overdrive harmonic balancer is used alone and will overdrive the supercharger 14%. The balancer can also be used in conjunction with the Lingenfelter 2.60 inch diameter supercharger driven pulley upgrade kit for higher boost levels of 18 - 19 lbs but would require higher octane fuel.
