Maximum Gen 6x Performance for the Mustang Bullitt
The Whipple Stage 2 Gen 6x Supercharger Kit is the ultimate street-legal power solution for the 20192021 Ford Mustang Bullitt 5.0L. Built around Whipples most advanced Gen 6x 3.0L front-feed twin-screw supercharger, this complete bolt-on system delivers extreme horsepower, instant torque, and OEM-level drivability while remaining fully emissions compliant in all fifty states.
At the core of the system is Whipples revolutionary Gen 6x W185AX 3.0L supercharger, featuring an exclusive 3x4 rotor combination, increased helix angle, optimized discharge port, redesigned bell-mouth inlet, and all-new bearings and gears. This design allows the supercharger to spin faster and more efficiently, producing substantially more airflow under the curve than traditional 4x4 roots-style designs.
The Stage 2 configuration adds a billet 132mm Roval electronic throttle body and high-flow dual-beam fuel injectors, unlocking the airflow and fueling capacity required for serious power. Whipples patented dual-core, dual-pass intercooler system, combined with the industrys largest heat exchanger, oversized coolant reservoir, and high-flow intercooler pump, delivers unmatched charge-air cooling and rapid recovery after hard use.
On premium pump gas, the system produces up to 825 horsepower and 655 lb-ft of torque on 93 octane. With instant boost at throttle tip-in, a flat torque curve, and relentless pull to redline, this Stage 2 system transforms the Bullitt into a dominant yet dependable street machineno cutting, hood modifications, or additional upgrades required.
