SPE Motorsport Coyote Gen 4 & 5 Whipple 5-Bolt 10 Rib Blower Pulley

SPE's CKP blower pulley for the Whipple 5-bolt, 10-rib supercharger drive, built for Coyote Gen 4 and Gen 5 platforms pushing beyond factory boost levels.

Features & Benefits

• Patent-pending CNC Convex Knurling Process (CKP) surface offers more grip under load than laser-etched pulleys, without wearing off over time
• Increases boost, horsepower, and torque over the factory pulley
• Reduces rotational mass versus the factory pulley
• 10-rib sizes ranging from 2.4" to 3.0" — every 0.100" smaller adds roughly 1 PSI of boost

Fitment: Fits Whipple 5-bolt, 10-rib superchargers on the Coyote Gen 4 and Gen 5 platforms.
