Whipple Supercharger Kit W185RF Gen 6x 3.0L (20162020 Shelby GT350) WK-2621-30
Gen 6x Twin-Screw Supercharger System for the Shelby GT350
The Whipple W185RF Gen 6x 3.0L Supercharger Kit represents the most powerful, most advanced, and most complete bolt-on supercharger system available for the 20162020 Shelby GT350. Featuring the same Gen 6x 3.0L twin-screw technology used in the 2018 Cobra Jet, this system sets a new benchmark for airflow efficiency, cooling capacity, and emissions-legal performance.
On 93 octane fuel, the system delivers up to 875 horsepower and 660 lb-ft of torque at the engine, nearly doubling factory output while maintaining exceptional drivability. The updated Gen 6x supercharger features a new rotor profile and high-flow housing, producing more power per pound of boost than any competing positive-displacement system.
Airflow is managed through a billet 132mm Roval electronic throttle body and 123mm high-flow intake system, while cooling is handled by Whipples patented dual-core, dual-pass intercooler design. Each intercooler core is used twice, delivering unmatched thermal efficiency. A massive heat exchanger and high-flow intercooler pump ensure consistent power even under extreme conditions.
Fueling and calibration are fully addressed with billet fuel rails, high-flow fuel injectors, and the included HP Tuners Whipple RDT flash tool. Whipples proprietary PCM calibration optimizes fuel, spark, torque management, and knock control while retaining factory safety strategies and emissions compliance.
