The compressor helps the engine to achieve a power increase from standard 223 hp / 164 kW to about 325 hp / 239 kW. Maximum torque is increased to about 435 Nm. The engine conversion reduces the acceleration time from 0 - 100 km/h to about 8.4 seconds, maximum speed is about 210 km/h.

The supercharger kit for the HUMMER H3 will be available from fall 2005 when the development is finished. A cat-back sport exhaust system will be available soon. The exhaust system doesn't only deliver a more exciting engine sound but also a more spectacular look due to its two large chromed exhaust tips.
