50-State Legal Gen 6 Twin-Screw Power for the S550 Mustang GT
The Whipple Stage 1 Gen 6 3.0L Supercharger Kit sets a new benchmark for emissions-legal performance on the 20182021 Ford Mustang GT 5.0L. Built around Whipples groundbreaking Gen 6 front-feed 3.0L twin-screw supercharger, this complete bolt-on system delivers an impressive 750 horsepower and 640 lb-ft of torque at the flywheel on 93 octanewith OEM-level drivability and long-term reliability.
At the heart of the system is Whipples latest 3x4 rotor combination with a 285-degree helix angle, redesigned bearings, gears, and housing for higher RPM capability and exceptional efficiency across the entire powerband. The oversized Crusher 150mm Roval inlet supports throttle bodies up to 150mm, ensuring massive airflow with minimal rotor cavitation.
Cooling is handled by Whipples patented dual-core, dual-pass intercooler system, where each intercooler core is utilized twice for unmatched thermal efficiency. Paired with an industry-leading heat exchanger, high-flow intercooler pump, and large water reservoir, this system maintains consistent IATs and rapid recovery during aggressive street or track use.
Included HP Tuners RTD flash tool and Whipples exclusive PCM calibration precisely manage fuel, spark, torque, throttle, and knock control. The result is massive, repeatable power that remains CARB certified and legal in all 50 states.
