Lingenfelter LSA Overdrive Balancer Kit

The Lingenfelter CTS-V, Camaro ZL1 supercharger overdrive harmonic balancer upgrade kit is designed to enhance the 2009-2012 LSA supercharged engine. The LPE overdrive harmonic balancer kit produces excellent horsepower and torque improvements over the factory 556 horsepower and 551 lbs ft of torque while maintaining a safe level of boost and 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. 

The Lingenfelter CTS-V, Camaro ZL1 overdrive harmonic balancer hub can be used with our 5%,10%, 18% or 22.5% overdrive supercharger balancer pulley which is a required separate item. 

Testing at Lingenfelter has shown over 40 rear wheel horsepower improvement and over 3.5 lbs of boost with the 10% overdrive balancer pulley installed with the stock supercharger pulley on an otherwise stock engine. 

With tuning the LPE LSA overdrive harmonic balancer can be used alone or with fuel system upgrades it could be used in conjunction with our supercharger driven pulley upgrade kit for higher boost levels.
