2020-2022 Ford Shelby GT500 5.2L Predator Gen 6 3.8L Whipple Supercharger Upgrade Kit

2020-2022 FORD SHELBY GT500 5.2L PREDATOR
GEN 6 3.8L WHIPPLE SUPERCHARGER UPGRADE KIT

If you're craving more power from your Shelby GT500, Whipple has the answer. The Gen 6 3.8L Whipple supercharger upgrade kit is built for 2020-2022 Ford Shelby GT500 applications and delivers the kind of airflow, cooling capacity, and premium engineering expected from the leader in twin-screw supercharging. The result is a package that completely changes how the Predator platform responds, with harder acceleration, stronger mid-range, and relentless pull at the top of the RPM range.

Since 1987, Whipple Superchargers has been at the forefront of twin-screw supercharging technology, developing complete systems for enthusiasts who want real engineering, real drivability, and real results. Manufactured and assembled at Whipple’s facility in Fresno, California, the WK-2550-38 reflects that in-house design and development approach from top to bottom. This is not a generic upgrade built around compromise. It is a complete Whipple system engineered specifically for the factory GT500 platform.

At the center of the package is the Whipple Gen 6 W235ax 3.8L twin-screw supercharger. Compared to the factory 2.65L roots-style supercharger, the larger 3.8L design offers 43% more displacement, allowing it to move the same air with lower power draw and lower discharge temperatures while delivering the broad, immediate torque curve Whipple systems are known for. On 93-octane fuel with a 100% stock engine and exhaust, this system is capable of producing up to 1035 horsepower with 16 psi of boost.

Airflow is supported by a billet 132mm throttle body and Whipple’s unique 145mm high flow cold air intake system with oversized air filter. Fueling, belt control, and installation hardware are all engineered to work together as a complete package, including billet idler components, motor mount brackets, supercharger belt, and the hardware needed for clean installation. The included motor mount bracket system is designed to provide the clearance needed to package the larger 3.8L system properly under the stock hood.

Cooling performance is one of the biggest reasons this system stands apart. The patented dual core, dual pass intercooler technology gives the discharged air two passes through the intercooler system, dramatically increasing cooling effectiveness versus the stock arrangement. Combined with the massive dual-core design and high-capacity intercooler system, the Whipple package delivers the kind of repeatable cooling performance needed to support serious GT500 power levels.

For GT500 owners who want serious power without giving up refinement, this system delivers the best of both worlds. It offers the airflow, cooling capacity, and proven engineering expected from a premium Whipple package while remaining CARB certified and 50-state legal. That combination of power, confidence, and complete system engineering is what makes the Gen 6 3.8L Whipple upgrade one of the strongest supercharger options available for the Shelby GT500 platform.
