Beefcake Special Whipple Gen 6 3.8L Supercharger Kit (2018–2023 Mustang GT)
The Beefcake Special Whipple Gen 6 3.8L Supercharger Kit is one of the most aggressive and power-capable packages available for the 2018–2023 Ford Mustang GT 5.0L Coyote. Built around Whipple’s massive 3.8L Gen 6 supercharger, this Beefcake Special is designed for enthusiasts chasing extreme horsepower while retaining street manners and long-term reliability.
As with all Beefcake Specials, this kit combines premium, proven components that have been tested both on the street and at the track. The result is a matched system that delivers exceptional airflow, cooling, and fueling support—ready for serious power now and even more down the road.
Why the 3.8L Beefcake Special?
The Whipple Gen 6 3.8L twin-screw supercharger offers significantly more airflow capacity than smaller displacement units, allowing it to make big power at lower blower speeds. This means cooler charge temps, reduced parasitic loss, and massive power potential when paired with proper fueling and tuning.
Beefcake Racing enhances the base Whipple tuner kit with upgraded injectors and a fuel pump booster, giving you a solid foundation for high-horsepower builds while maintaining excellent drivability.
