Whipple Stage 2 Intercooled Supercharger Kit 3.0L Gen 6 (20152017 Mustang GT) WK-2620-STG2-30
Stage 2 Gen 6 3.0L Power for the S550 Mustang GT
The Whipple Stage 2 Intercooled Supercharger Kit featuring the Gen 6 W185RF 3.0L twin-screw supercharger represents the most powerful 50-state legal bolt-on system available for the 20152017 Mustang GT 5.0L. Designed for enthusiasts who want maximum street-legal performance, this complete system delivers massive horsepower, instant torque, and factory-level drivability.
At the heart of the system is Whipples sixth-generation 3.0L supercharger, utilizing a newly engineered rotor profile and high-flow rotor housing to dramatically improve airflow, efficiency, and thermal control. This is the same advanced technology used in the 2018 Ford Cobra Jet, setting the benchmark for positive-displacement supercharging performance.
The Stage 2 configuration builds on the Stage 1 foundation with the addition of a billet 132mm Roval electronic throttle body and high-flow fuel injectors, ensuring the airflow and fueling capacity required for extreme power levels. Whipples patented dual-core, dual-pass intercooler system, combined with a massive heat exchanger and high-capacity intercooler pump, delivers industry-leading charge-air cooling.
The result is up to 825 horsepower and 640 lb-ft of torque on 93 octane, nearly doubling the stock output of the S550 Mustang GT. With instant boost, a flat torque curve, and consistent power delivery to redline, this system transforms the Mustang into a dominant yet dependable street machine.
