Gen 6x Supercharger Technology
At the core of this system is Whipples Gen 6x W185RF 3.0L twin-screw supercharger, featuring an all-new housing, inlet, and pulley design for improved airflow efficiency. The exclusive 3x4 rotor combination increases RPM capacity while minimizing leakage paths, allowing the supercharger to move more air with lower discharge temperatures.
The inverted, front-entry design allows Whipple to package an oversized intercooler system unmatched by any other positive displacement supercharger on the market, delivering more power per pound of boost than competing roots-style systems.
Cooling & Fuel System Upgrades
Whipples patented dual-core, dual-pass intercooler system routes charge air through each intercooler core twice, effectively doubling thermal efficiency compared to conventional designs. Combined with the largest dual-pass heat exchanger available and a high-flow intercooler pump, intake air temperatures stay stable even under sustained load.
Stage 2 kits include GT500 Bosch dual-beam fuel injectors, providing the fuel volume and spray pattern required to safely support high horsepower on pump gas with OEM-level reliability.
Tuning & Transmission Control
Each system includes the Whipple Tomahawk V2 flash tool with a proprietary Whipple calibration developed using factory-level software. The calibration fully integrates with the F-150s locked PCM and recalibrates fuel, spark, torque management, knock control, throttle mapping, and transmission behavior.
The advanced 10-speed transmission is recalibrated to keep the engine in its optimal torque range while retaining all factory drive modes, including tow, eco, sport, and off-road. Wheel, tire, and axle ratio adjustments are supported directly through the Tomahawk tool.
