{"product_id":"w175ax-2-9l-supercharger-upgrade-kit","title":"W175AX 2.9L Supercharger Upgrade Kit","description":"The Whipple W175AX 2.9L Supercharger Upgrade Kit (WHP-WK-2110T) is engineered to significantly enhance the performance of 2003-2004 Ford Mustang Cobra models, specifically those utilizing an aftermarket oval throttle body configuration. This kit represents a substantial upgrade from the stock Eaton supercharger, delivering improved airflow, reduced charge air temperatures, and more usable power across the entire RPM range.\n\nAt its core is Whipple's 4th generation W175AX 2.9L twin-screw supercharger. The HPR (High Pressure Ratio) design is optimized for higher boost levels, capable of supporting nearly 25 PSI with the necessary supporting engine modifications and calibration. The integrated air bypass system ensures proper function, lower discharge temperatures, and reduced parasitic loss, while the discharge plate design enhances plenum area and air distribution across the intercooler core.\n\nThis direct bolt-on kit offers a straightforward installation, estimated at approximately 6 hours, and is described as simple for most enthusiasts. For stock applications targeting a 13 PSI boost level, no engine or PCM modifications are required, and the stock fuel system is acceptable. However, boost levels exceeding 13 PSI will necessitate custom PCM calibration and appropriate supporting upgrades, such as fuel system and throttle body enhancements. The kit does not include tuning, fuel system, throttle body, or cold air intake unless otherwise specified. This upgrade is built for customers aiming for a serious street or race-oriented Cobra combination.","brand":"Whipple Superchargers","offers":[{"title":"Default Title","offer_id":52664125260088,"sku":"WHP-WK-2110T","price":5199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687540992.jpg?v=1784333639","url":"https:\/\/store.motormia.co\/products\/w175ax-2-9l-supercharger-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
