Saleen by Kenne Bell 2.1L Twin-Screw Supercharger Package 1999-04 4.6L Ford Mustang

Saleen uses a twin-screw intercooled design for our superchargers. We have found that this provides for greater air compression over roots and centrifugal type units. If you are not familiar with the intercooled twin-screw supercharger, it is the supercharger of choice and the only style that we use on our current and past production vehicles. It's provides the best performing ability to provide cool air at the highest compression for efficient power-on-demand.

On the 1999-2004 Saleen we boost the unit to the safest amount recommended before considering engine internals and/or higher flowing fuel pumps to support additional boost. With this unit, we are able produce an increase in Rear Wheel Horsepower (RWHP) on the 4.6L by 160HP; however there are variables such as fuel octane type, exhaust flow, etc. to accommodate for less than optimum conditions.

This is a COMPLETE unit. No extra brackets, intercoolers, fuel lines, etc. are needed. Follow the instructions and you'll have everything needed to complete the installation on the vehicle including calibration.
