Ford Mustang GT 3.0L Supercharger Kit 2018-2021

Description

Whipple Superchargers continues to raise the bar with the Gen 6 3.0L front‑feed twin‑screw supercharger system for the 2018–2021 Ford Mustang GT. Building on the record‑breaking S550 platform, this next‑generation system delivers exceptional efficiency, insane horsepower capability, and OEM‑level drivability—all while remaining 50‑state emissions compliant.

Across Stage 1 and Stage 2 configurations, the Gen 6 system produces an impressive 750–825 flywheel horsepower and 640–655 lb‑ft of torque, offering a massive leap in performance compared to previous generations.

The Gen 6 supercharger introduces Whipple’s most advanced engineering to date, featuring new bearings, gears, rotor profiles, and housing improvements designed to reduce friction and maximize airflow. The updated rotor pack uses a 3/4 rotor combination, a 285‑degree helix angle for optimized intake efficiency, a redesigned bell‑mouth inlet, an improved discharge port, and a refined diameter‑to‑length ratio that enhances power across the entire RPM range.

Supporting this airflow is Whipple’s patented dual‑core, dual‑pass intercooler—designed to outperform even Cobra Jet systems and previous S550 intercooler designs. Together with the oversized heat exchanger, water reservoir, and high‑flow intercooler pump, the system ensures consistent charge‑air temperatures, reduced heat‑soak, and fast recovery during intense driving.

Whipple’s custom PCM calibration is crafted from decades of OEM and motorsports tuning expertise. This software precisely manages fuel delivery, spark timing, knock control, torque management, electronic throttle behavior, and transmission logic. The PCM constantly monitors engine torque output to maintain maximum performance and long‑term reliability. Paired with the HP Tuners RTD flash tool, users benefit from unmatched control and update flexibility.

Each complete Whipple kit includes an IAT2 harness and sensor for accurate post‑intercooler temperature monitoring. The billet 6‑rib idler system includes a billet spring‑loaded tensioner, billet idler pulleys, and a lightweight pocketed supercharger pulley. A 10‑rib drive upgrade is available for higher‑boost configurations. An adjustable idler pulley allows for easy belt tensioning and supports a wide range of pulley sizes.

With its unmatched balance of power, efficiency, reliability, and cooling performance, the Whipple Gen 6 supercharger system sets a new benchmark for the 2018–2021 Mustang GT—delivering a brutally powerful yet refined driving experience that redefines what a modern supercharger system can achieve.
