Product Description

The VelocityAP Supercharger Crank Pulley is one of the most effective bolt-on power upgrades available for the Jaguar F-Type V6 and V8 Supercharged platforms. Designed to increase supercharger speed and boost pressure, this oversized lower pulley dramatically improves horsepower, torque, and throttle response while maintaining OEM-like drivability when paired with the proper ECU calibration.

Unlike smaller upper pulley upgrades, the larger lower crank pulley generates substantial boost increases with improved belt wrap and reliability, making it a preferred solution for enthusiasts chasing significant real-world performance gains. VelocityAP engineered this pulley system specifically around the AJ126 and AJ133 supercharged engines, with extensive dyno testing and road validation to ensure safe, repeatable performance.

When combined with VelocityAP ECU tuning, customers routinely report the car feeling completely transformed, with dramatically stronger mid-range torque and significantly improved acceleration. For many Jaguar enthusiasts, this modification represents the turning point where the F-Type finally feels as aggressive as it looks and sounds.
