Whipple Supercharger Upgrade Kit W140AX 2.3L (2003–2004 Cobra w/ Stock Throttle Body) – WK-2100T

High-Efficiency Twin-Screw Upgrade for the 2003–2004 Cobra Terminator

The Whipple W140AX 2.3L Supercharger Upgrade Kit is a direct bolt-on replacement designed specifically for the 2003–2004 SVT Cobra using the factory throttle body. Engineered as a high-efficiency upgrade over the stock Eaton roots blower, this Whipple system delivers more power, cooler charge temperatures, and significantly reduced parasitic loss—all while maintaining instant boost and factory-like drivability.

At the core of the kit is Whipple’s W140AX 2.3-liter twin-screw supercharger, capable of achieving up to 95% efficiency. Compared to the factory Eaton, the Whipple produces less heat, consumes less horsepower to drive, and maintains boost across the entire RPM range with no boost drop-off.

This system is designed to bolt directly in place of the factory supercharger and supports a wide 8–25 psi boost range depending on pulley selection and engine modifications. Out of the box, the kit includes everything required to run 13 psi of boost with zero engine or PCM modifications, making it an ideal upgrade for both stock and heavily modified Terminator builds.
