2007-2014 Ford Shelby GT500 5.4L/5.8L Whipple Gen 5 3.8L Supercharger Upgrade Kit

This Whipple Gen 5 3.8L twin-screw supercharger system is purpose-built for the 2007-2014 Ford Shelby GT500 5.4L/5.8L, reaching well into four-figure horsepower territory with the right supporting components — this is a tuner kit engineered for a custom-calibrated build, not a fixed power-level system. Every system is engineered, machined, and assembled in-house at Whipple's Fresno, California headquarters as a complete, matched package — not an assortment of parts pieced together.

This is a full Gen 5 3.8L twin-screw supercharger with an advanced 3/4 asymmetrical rotor design, replacing the factory Eaton unit outright. It includes a 132mm Roval throttle body and a 123mm cold air intake. The high-flow housing is built for serious race-oriented power potential, with output well into four figures achievable given the right supporting components. The kit mounts to the factory lower intake manifold and is designed to run on the factory injectors, fuel rails, heat exchanger, and MAF sensor as its base configuration.

This is a tuner kit intended for a custom-calibrated build: it requires a custom tune after installation and does not include a fuel system, programmer, or tuning.

Emissions status: no current CARB Executive Order number was found published for this specific kit as of our research date — verify current emissions compliance with Whipple before selling into California or other CARB-regulated states.
