ATI 7.480" Dia., 2012+ ZL1, '09-'15 CTS-V Harmonic Damper
Details
The ATI CTS-V and Camaro ZL1 supercharger overdrive harmonic balancer upgrade kit is designed to enhance the 2009-2014 LSA supercharged engine. The ATI 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.
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.
No supercharger pulley supplied. Must add 916105, 916106, 916153 pulley of your choice.
