Pulley - Supercharger - 8-Groove - Cadillac

The ATI Performance Pulley – Supercharger – 8-Groove for Cadillac is a precision-engineered serpentine pulley designed to optimize supercharger performance specifically for compatible Cadillac supercharged models. Built by ATI Performance, a trusted name in high-performance engine accessories, this pulley replaces the factory unit to improve boost delivery and enhance overall drivetrain efficiency.

The 8-groove design increases belt contact area compared to standard 6-groove units, delivering superior grip and reduced slippage during high-load acceleration. This geometry allows the supercharger to spool more efficiently, translating engine revolutions into boost pressure with minimal parasitic loss. ATI's manufacturing standards guarantee concentricity and balance within OEM tolerances, critical factors for drivability and longevity at elevated boost levels.

Cadillac owners running CTS-V, XLR-V, or other supercharged models benefit most from this upgrade, particularly those tuning for sustained power output or competing in timed events. Professional tuners and serious enthusiasts favor ATI pulleys for their reliability and performance, making this an essential component for any serious Cadillac performance build.
