Wheel to Wheel will bring the AMM dual speed supercharger into the Hummer H3.

The major limitation of centrifigual superchargers is low end boost. Antonov has addressed this situation, with a two speed supercharger drive. The drive creates a 1.36:1 input speed increase, which in turn increases the supercharger impeller speed. The charger is shifted out of gear, as a function of load and speed.

Combined Antonov Rotrex supercharger head units are available by special order. It will also be offered as an option on our I5 (Hummer H3, Colorado/Canyon supercharger systems)
