2016-2020 Ford Shelby GT350 / GT350R 5.2L Gen 6x 3.0L Whipple Supercharger Kit

2016-2020 FORD SHELBY GT350 / GT350R 5.2L
GEN 6x 3.0L WHIPPLE SUPERCHARGER KIT

The Shelby GT350 and GT350R are already special cars, but a properly engineered Whipple twin-screw system takes the 5.2L platform into an entirely different league. The instant torque, violent mid-range pull, and relentless charge to redline completely change the personality of the car while preserving the refinement expected from a premium Shelby build. That is exactly what Whipple delivers with the Gen 6x 3.0L supercharger system for the 2016-2020 GT350 and GT350R.

Since 1987, Whipple Superchargers has been a leader in twin-screw supercharging technology, designing complete systems for enthusiasts who want real engineering, real drivability, and real power from a package built to work as a system. Manufactured and assembled at Whipple’s facility in Fresno, California, the WK-2621-30 reflects that in-house design and development approach from top to bottom. This is not a compromise kit built around generic parts. It is a complete, thoroughly developed Whipple system engineered specifically for the Shelby GT350 and GT350R platform.

At the center of the package is the Whipple Gen 6x W185ax 3.0L twin-screw supercharger. Compared to smaller 1.9L and 2.3L roots-style systems, the larger 3.0L design moves more air with less effort, helping reduce discharge temperatures and parasitic loss while delivering the broad, immediate torque curve Whipple systems are known for. On 93-octane fuel under optimal conditions, the system is capable of producing up to 875 horsepower and 660 foot-pounds of torque, making it one of the most compelling supercharger options available for the GT350 platform. The legacy GT350 product copy also positions this as the most powerful 50-state legal system in the family.

The GT350 package is built with the airflow and fuel support needed to match the engine’s higher-revving nature. A billet 132mm Roval electronic throttle body works with the high-flow inlet system to increase airflow capacity, while billet fuel rails and high-flow fuel injectors support the added power. The included HP Tuners MPVI4 flash tool and Whipple calibration support provide the tuning foundation needed for a properly integrated package.

Cooling performance is another major reason the Whipple system stands apart. The patented dual intercooler, dual pass technology works with a massive heat exchanger and high flow intercooler pump to help control air charge temperatures under demanding conditions. The front-feed layout also allows for an oversized intercooler core compared to smaller competing systems, helping the Whipple package maintain stronger, more consistent performance when heat becomes the enemy.

For GT350 and GT350R owners who want a complete, high-horsepower package backed by proven Whipple engineering, this system checks every box. It delivers the airflow, cooling capacity, fuel support, and premium drivability expected from a top-tier Shelby upgrade while remaining CARB certified and 50-state legal. That combination of power, refinement, and engineering confidence is what makes the Whipple Gen 6x 3.0L system one of the strongest supercharger options on the market for Ford’s flat-plane-crank Shelby platform.
