It's understandable, then, that Vortech had an appropriate '11 Mustang GT supercharger-the self-lubricated V-3 in Si-Trim-already spinning away under the hood of Three-Valve Mustangs.

With our smallest 2.85-inch pulley the Aluminator soared to 905.7 hp and 717.4 lb-ft. When peak power occurred, we made 14.0 psi of boost, netting an additional 33.8 hp per psi of boost.

The result is less belt slip, more boost, and more power. To test this for ourselves, we installed GripTec's pulley and hub system on a 2018 Mustang GT equipped with a Vortech supercharger.

Combine that with the 1.74:1 pulleys, and the impeller spins almost 36,000 rpm when the engine is running 6,000. And thats actually low for a Vortech, delivering barely 3 pounds of boost to our 383.
