Supercharger Buyer's Guide for the S197 Mustang GT

A guide to the available supercharger applications for the 2005-2007 Mustang GT

Supercharging your Mustang GT is one of the simplest ways to increase the 4.6-liter 3-valve V8 engine by 25% or more. With the Mustang's popularity, several manufacturers have come out with supercharger systems adding anywhere from 100 to 500 horsepower depending on boost and other modifications. Twin-screw, roots type, and centrifugal applications are available ranging from simple setups designed for drivability to high boost setups for drag racing. We have outlined many of the various applications so you can see the systems side by side.
