Pulley - Supercharger - 8-Groove - Cadillac

The ATI Performance Pulley - Supercharger - 8-Groove for Cadillac is a high-performance crankshaft drive pulley engineered for forced-induction applications on select Cadillac models, including the CTS-V with LSA supercharger. This aluminum pulley features an 8-rib serpentine design with a diameter of 8.295 inches and is finished in black anodized coating for durability and corrosion resistance. Designed to work seamlessly with the ATI damper system, this pulley serves as a critical component in the supercharger drive chain, transmitting engine rotation directly to the supercharger compressor.

Specifications matter in supercharger systems because pulley size and rib count directly affect boost delivery and compressor speed. The 8-groove configuration ensures optimal belt grip and power transfer while minimizing slippage under high engine loads. Aluminum construction keeps rotating mass low, which reduces inertial losses and allows the engine to spool the supercharger more efficiently. The black anodized finish provides UV and corrosion protection, essential for long-term reliability in underhood environments. This pulley integrates with OEM or performance cooling and belt systems common to LSA-equipped vehicles.

This pulley is intended for owners of supercharged Cadillac vehicles—particularly CTS-V platform builds—who are replacing worn factory pulleys or upgrading to a performance-oriented damper and pulley package. Supercharger drive components experience constant high-speed rotation and significant thermal cycling. OEM pulleys can wear grooves, slip under peak boost, or suffer premature failure. Replacing the pulley as part of preventive maintenance or during a supercharger rebuild ensures consistent boost delivery, reduces parasitic losses, and maintains the integrity of the belt drive system.

ATI Performance is recognized in the performance automotive industry for precision dampers and accessory drive components designed to handle high-horsepower, forced-induction engines. The ATI damper system and companion pulleys are engineered for durability and tuning accuracy, making them a choice for both street and track applications where reliability under boost matters.
