2.75" 10-Rib SCP Supercharger Pulley

The Whipple 2.75" 10-Rib SCP is a high-performance supercharger pulley engineered for specific Whipple supercharger applications. Machined from robust 6061-T6 billet aluminum, this pulley is hard-coated with a black anodized finish, ensuring excellent wear resistance and protection against environmental factors. Each pulley is meticulously engraved with its precise running diameter. Additionally, a guard feature is incorporated to help prevent unwanted belt wandering, especially during demanding driving conditions. This design promotes optimal performance and longevity for your supercharger system. A general rule of thumb suggests that every 0.125 inches of pulley change can result in approximately 1 PSI of additional boost. Please note that Whipple Supercharger pulleys are application-specific; ensure you order the correct pulley for your setup, as returns or exchanges are not permitted for used pulleys.
