Beefcake Special Whipple Gen 6 3.8L Supercharger Kit (2015–2017 Mustang GT)
The Beefcake Special Whipple 3.8L Gen 6 Supercharger Kit is built for serious S550 Mustang owners running modified or built 5.0L Coyote engines. This package pairs Whipple’s massive 3.8L supercharger hardware with proven fueling support to deliver extreme power capability while maintaining the drivability and reliability Beefcake Racing is known for.
Every component in this Beefcake Special is street- and track-tested and selected to work together as a system. The 3.8L displacement provides huge airflow headroom, allowing you to make big power at lower blower speeds—reducing heat and parasitic loss compared to smaller superchargers.
