Product Description

The ATI 916106 10% Overdrive Supercharger Pulley is the optimal solution for increasing boost on your supercharged LSA or LT4 engine without the belt slip issues associated with smaller supercharger pulleys. This precision-engineered 8.86-inch diameter, 8-groove pulley spins your Eaton supercharger 10% faster on LSA engines (8% on LT4), delivering 3.5-5.5 lbs of additional boost for significant horsepower and torque gains. The 8-rib serpentine design provides dramatically more belt surface contact than stock 6-rib systems, virtually eliminating belt slip under high-boost conditions. Manufactured by ATI Performance Products with over 55 years of high-performance racing expertise, this pulley features aluminum construction with a durable black anodized finish for corrosion resistance and professional appearance. Requires an ATI Super Damper for installation - compatible with ATI damper part numbers 918854 and 918856. This pulley will not work with the factory harmonic balancer. Ideal for 2009-2015 Cadillac CTS-V and 2012-2015 Camaro ZL1 with LSA engines, as well as 2016-2019 CTS-V and 2016-2021 Camaro ZL1 with LT4 engines. Professional installation and ECU tuning recommended to optimize performance gains. Made in USA.
