Whipple Stage 1 Gen 6x Supercharger Kit 3.0L (20192021 Mustang Bullitt) WK-2626-STG1-30
Gen 6x 3.0L Whipple Power for the Mustang Bullitt
The Whipple Stage 1 Gen 6x Supercharger Kit delivers cutting-edge, 50-state legal performance for the 20192021 Ford Mustang Bullitt 5.0L. Built around Whipples latest Gen 6x 3.0L front-feed twin-screw supercharger, this complete bolt-on system produces massive power while maintaining factory-like drivability and emissions compliance.
At the core is Whipples advanced Gen 6x W185AX 3.0L supercharger, featuring an exclusive 3x4 rotor combination, increased helix angle, optimized discharge port, and refined bell-mouth inlet. With all-new bearings, gears, rotors, and housing, the Gen 6x design delivers higher RPM capability, improved sealing, and greater airflow efficiency across the entire rev range.
This Stage 1 system is engineered to produce up to 765 horsepower and 640 lb-ft of torque on 93 octane, decisively outperforming smaller 2.3L and 2.65L roots-style systems. A massive dual-core, dual-pass intercooler, oversized heat exchanger, high-flow intercooler pump, and large coolant reservoir work together to keep intake air temperatures low and power consistent under demanding conditions.
Whipples OEM-level engineering extends to calibration as well. Each kit includes a Whipple-specific PCM calibration and HP Tuners RTD flash tool, optimizing fuel delivery, spark, torque management, throttle control, and knock strategy. The result is instant boost, a flat torque curve, and reliable performance that pulls hard from tip-in to redline.
