Mustang Supercharger Buyers' Guide - Air Force Special
Nothing Does The Horsepower Rush Quite Like A Blower
Through its Speedlab Parts division, Saleen Automotive offers a positive-displacement supercharger; the latest version of which is dubbed the Saleen Series VI. Like Kenne Bell and Whipple superchargers, it employs twin-screw rotors contained within a casing, in this case a 2.3L unit. However, that's where the similarities end. Instead of the supercharger forcing air down into the manifold, an inverse design draws air from the intake snorkel assembly and feeds into the blower. The result is a very neat, compact design that provides maximum airflow from a relatively low amount of boost (in this case 5 psi), reducing wear and stress on the engine internals. The Series VI kit also includes a specific Saleen Power Flash computer and is designed to work on '05-'06 Mustangs equipped with the 4.6L V-8.
Besides the Series VI, Saleen still offers its Series IV Roots blower, a version of which was first seen on production S281 Supercharged cars in 2000. This is designed as a direct bolt-on for all Mustangs using the 4.6L single overhead cam V-8 in PI form ('99-'04). It comes as a complete kit with a replacement aluminum intake manifold, larger 30-pound injectors, an intercooler, a heat exchanger, and a specially calibrated performance tune.
