2003-2004 Ford Mustang Cobra W140AX 2.3L Whipple Supercharger Upgrade Kit for Stock Throttle Body

2003-2004 FORD MUSTANG COBRA
W140AX 2.3L WHIPPLE SUPERCHARGER UPGRADE KIT
FOR STOCK THROTTLE BODY

Few upgrades wake up a Terminator Cobra like replacing the factory Eaton with a larger, more efficient twin-screw supercharger. For owners looking for stronger airflow, lower charge temperatures, and more usable power throughout the RPM range while retaining the stock throttle body configuration, the Whipple W140AX 2.3L upgrade remains one of the most proven paths forward for the 2003-2004 Cobra platform.

Whipple Superchargers has been at the forefront of twin-screw supercharging technology since 1987, engineering some of the most powerful and efficient forced-induction systems in the industry. That experience carries directly into the WK-2100T, a W140AX 2.3L Whipple supercharger upgrade kit built specifically for 2003-2004 Ford Mustang Cobra applications using the factory stock throttle body.

At the center of the system is Whipple's W140AX 2.3L twin-screw compressor, designed to deliver more airflow, cooler charge temperatures, and less parasitic loss than the factory Eaton roots-style supercharger. The result is stronger throttle response, improved top-end performance, and the broad, immediate torque delivery that Terminator owners want from a properly engineered positive-displacement upgrade.

This system is a direct bolt-on replacement for the factory supercharger and is designed to work as a serious performance upgrade on stock 4.6L Cobra engines as well as more heavily modified combinations. The system supports a boost range from 8 to 25 psi depending on engine setup and supporting components. The complete bolt-on system includes the necessary parts for a 13 psi configuration, which requires no modifications to the engine or PCM on stock applications.

The WK-2100T is the version intended for customers retaining the factory throttle body, making it the more stock-style upgrade path within the Cobra W140AX family. For customers looking to move beyond the factory Eaton and build a stronger, more capable Cobra combination without changing throttle body style, this Whipple system delivers a proven high-flow foundation.
