Whipple W175AX 2.9L SC Upgrade Kit *For Use With Aftermarket Oval Throttle Body* Shelby Cobra 2003-2004

If your craving more power from your Cobra Terminator, Whipple has the answer. Get the industries most efficient and latest designed, 50-Stage Legal twin-screw supercharger available today. Featuring the new, 4th generation Whipple 2.9L supercharger with an all new rotor profile and new high flow rotor housing to unleash even more power than ever before. The new Whipple system can produce incredible power levels with stock 4.6L Cobra engines as well as highly modified engines. The revolutionary new W175ax compressor has the ability to run nearly 25lbs of boost (engine modifications required) for unheralded performance.

This direct bolt-on replacement system dramatically lowers supercharger air temperatures and power consumption (hp) versus the factory Eaton roots-type supercharger. The complete bolt-on system comes with all the necessary parts for 13lbs of boost which requires zero modifications to the engine or PCM. The Whipple W175ax HPR (High Pressure Ratio) is optimizied for the higher boost levels many crave. Available with the standard inlet for mono-blade throttle bodies.

The Whipple Cobra kit not only offers a better supercharger, but the potential to have one of the fastest, most powerful street machines on the road today. The Whipple discharge plate offers far more plenum area as well as a much greater radius to help distribute the air evenly over the entire intercooler core. The air bypass system is properly engineered into the SC discharge for proper function unlike other shrouded systems. This allows lower discharge temps and less parasitic losses during operation.


Shelby Cobra 2003-2004
Notes: Stock fuel system and factory PCM is ok for 13psi on stock engines. Engines with boost levels above 13psi will require custom PCM calibrations. Kits do not include tuning, fuel system, TB, or cold air unless noted.
