It tachs out in all three gears...has a built up turbo 400. 6,000 rpm max. We changed it to a torque cam so it will tow anything we want up a hill at 70! Horse power i think is around 500. Torque 480-500. He and i love the power! He likes it enough to peel out from the gas station just to turn around and re-fill the fuel tanks!!!! HAHAHA!!
