Designed for the baddest, most powerful 2003 to 2004 SVT Cobras, these aftermarket supercharger kits are purposely built to give your 4V 4.6L Modular V8 a borderline insane horsepower output. These Cobra Whipple supercharger kits have a Lysholm twin-screw design that is up to 90% efficient, providing your Cobra with loads of horsepower across the entire RPM range. Variations are available from 2.3L to 4.0L displacements, giving you a good range of power options for your Cobra build. The most powerful kits are the "Crusher" systems that can produce up to 30psi of boost pressure and push your Cobra to its absolute limits.
