Selling a classic, highly sought-after Whipple W140AX 2.3L twin-screw supercharger kit ($2,850), engineered in the USA for the iconic 2003–2004 Ford Mustang SVT Cobra 4.6L 4V. Verified via Whipple casing numbers (140-5227) and Ford Racing manifold stampings (2R3V-9J447-BB), this setup delivers instant boost, cooler intake temperatures, and high-rpm airflow far surpassing the stock Eaton M112. The unit is in clean, fully functional shape with smooth rotor spinning, tight tolerances, and normal cosmetic wear. This complete bolt-on package includes the Whipple 2.3L compressor head, Ford Racing intake manifold, integrated water-cooled intercooler core, Accufab high-flow oval throttle body, intake elbow, and mounting hardware. I originally acquired this compressor setup for a custom marine engine build, but due to dropping the blown-intake concept, I've had to shelve the project and let it go.
