Gen 6 W185ax 3.0L Twin-Screw Supercharger Stage 1 Kit

The Whipple Stage 1 Supercharger Kit, featuring the Gen 6 W185RF 3.0L twin-screw supercharger, is designed as the most advanced, emissions-legal bolt-on power upgrade for the 2018-2020 Ford F-150 5.0L. At its core is Whipple's latest Gen 6 3.0L twin-screw design with updated G6 rotors and a refined housing for improved efficiency and airflow. The inverted supercharger integrates cleanly into the engine valley, routing air through Whipple's patented dual-core, dual-pass intercooler system, which passes air through each intercooler twice for industry-leading thermal efficiency. On premium fuel, the Stage 1 system is capable of producing up to 725 horsepower and 625 lb-ft of torque at the flywheel. A massive heat exchanger and high-flow intercooler pump work together to maintain consistent intake air temperatures under load. Whipple's proprietary PCM calibration ensures reliable performance across all drive modes, including tow, eco, sport, and off-road. Designed as a true bolt-on, this kit installs without cutting or grinding. It includes Whipple's HP Tuners RDT OBDII flash tool for calibration loading, diagnostics, data logging, and vehicle configuration. This results in instant boost, a flat torque curve, and unmatched drivability from tip-in to redline. The kit is 50-state legal and CARB certified (EO D-231-71), and includes 56 lb/hr fuel injectors and spark plugs. It is designed to work on stock 5.0L F-150 engines running 91 octane or higher and does not require internal engine modifications. The system is compatible with the factory 10-speed transmission, with Whipple recalibrating it for optimal torque range and retaining factory drive modes.
