Whipple W175AX 2.9L Supercharger Upgrade Kit (WK-2110T) - 2003-2004 Ford Mustang Cobra Aftermarket Oval Throttle Body
Upgrade your 2003-2004 Ford Mustang SVT Cobra with the Whipple W175AX 2.9L Twin-Screw Supercharger Kit. Designed as a direct bolt-on replacement for the factory Eaton supercharger, the WK-2110T delivers increased airflow, cooler charge temperatures, and reduced parasitic losses. This version is specifically configured for aftermarket oval throttle bodies, making it an excellent choice for Terminator Cobra owners looking for greater horsepower potential and higher boost capability.
Featuring Whipple's 4th generation twin-screw technology, the W175AX 2.9L supercharger combines an updated rotor profile, high-flow housing, and High Pressure Ratio (HPR) design. The system is engineered to support nearly 25 PSI of boost when paired with the appropriate engine modifications, fuel system, and calibration.
4th Generation W175AX 2.9L Twin-Screw Supercharger
The W175AX features Whipple's 4th generation twin-screw compressor design with an updated rotor profile and high-flow rotor housing. Compared to the factory Eaton roots-type supercharger, this larger 2.9L compressor is engineered to move more air while reducing supercharger discharge temperatures and power consumption.
Its High Pressure Ratio (HPR) configuration is optimized for higher boost applications, providing additional performance potential for modified 4.6L Cobra engines. With the proper supporting components, the W175AX can support boost pressures approaching 25 PSI.
The positive-displacement design provides immediate boost response and broad torque delivery throughout the RPM range.
Improved Intercooler Airflow and Integrated Bypass System
The WK-2110T incorporates an upgraded discharge plate with increased plenum area to improve airflow distribution across the intercooler core. This design helps maximize the effectiveness of the vehicle's intercooling system while supporting the increased airflow of the 2.9L compressor.
An integrated air bypass system is engineered directly into the supercharger discharge for proper bypass operation, reduced discharge temperatures, and decreased parasitic losses.
Aftermarket Oval Throttle Body Compatibility
The WK-2110T is designed specifically for aftermarket oval throttle body configurations. This version supports Cobra owners using custom inlet and throttle body combinations rather than the factory stock throttle body arrangement.
Note: The throttle body is not included with this kit unless otherwise specified. Verify compatibility with the selected aftermarket oval throttle body before ordering.
Boost Capability and Calibration Requirements
The W175AX HPR supercharger is engineered for high-boost performance and can support nearly 25 PSI with the appropriate engine and supporting modifications.
The complete bolt-on kit includes the necessary components for a 13 PSI configuration. According to Whipple, this setup requires no engine or PCM modifications on stock applications, and the factory fuel system and PCM are acceptable for the supplied 13 PSI configuration.
Boost levels exceeding 13 PSI require custom PCM calibration and suitable supporting upgrades, including fuel delivery and other components appropriate for the intended power level.
Kit Contents: Tuning, fuel system components, throttle body, and cold air intake are not included unless specifically noted.
