55-75% More Power for H2’s

Intercooled ProCharger® systems for the Hummer H2 produce a 55-75% power gain on stock motors running pump gas, resulting in an undisputed industry best 560 horsepower with the Stage II system. These systems are 100% complete bolt-ons, and deliver the coolest charge air temperatures, for maximum engine longevity as well as power. This advanced technology not only improves the H2’s gas mileage, but also transforms the powerweight ratio from that of a typical large SUV to that of a sports car.
