Whipple 2007-2014 Shelby GT500 5.4L / 5.8L Gen 5 3.8L Supercharger Upgrade Kit Without Throttle Body & Cold Air Intake

Take your 2007-2014 Shelby GT500 to the next level with the Whipple Gen 5 3.8L Supercharger Upgrade Kit. Designed for high-performance street and race applications, this system replaces the factory supercharger with Whipple's latest Gen 5 3.8L twin-screw unit featuring an all-new 3x4 asymmetrical rotor design and redesigned high-flow housing. The result is increased airflow, greater efficiency, and the capability to support extreme horsepower levels.

This tuner upgrade kit is intended for custom performance builds and requires a custom calibration after installation. It mounts directly to the factory lower intake manifold while reusing the factory injectors, fuel rails, intercooler system, heat exchanger, and MAF sensor. The kit does not include a throttle body, cold air intake, fuel system, handheld programmer, or tuning, making it an ideal foundation for enthusiasts building a customized high-horsepower combination. With the proper supporting modifications, the Gen 5 3.8L supercharger is capable of supporting up to 2,000 horsepower in race applications.
