ATI 7.480" Diameter Harmonic Damper for 2012+ ZL1 & '09-'15 CTS-V
Details:
The ATI CTS-V and Camaro ZL1 Supercharger Overdrive Harmonic Balancer Upgrade Kit is engineered to elevate the performance of the 2009-2014 LSA supercharged engine. By overdriving the harmonic balancer, this kit boosts the supercharger's RPM, resulting in significant horsepower and torque gains beyond the factory ratings of 556 horsepower and 551 lb-ft of torque—all while maintaining safe boost levels and supercharger RPM.
Key Benefits:
- Enhanced Performance: Increases supercharger RPM to deliver superior horsepower and torque improvements.
- Optimized Safety: Maintains a safe boost level and RPM despite the performance gains.
- Precision Engineering: Designed specifically for the LSA supercharged engine in CTS-V and Camaro ZL1 models.
Note: This kit does not replace the driven supercharger pulley on the supercharger snout.
Upgrade your engine’s performance with the reliability and innovation of ATI.
Testing 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 ATI LSA overdrive harmonic balancer can be used alone or with fuel system upgrades it could be used in conjunction with a supercharger driven pulley upgrade kit for higher boost levels.
