Just to refresh everyone about engines: Engines make torque, not horsepower. The dyno measures torque and uses a formula to convert the torque to horsepower. Torque x engine speed/5,252 = HP. Therefore, torque and horsepower at 5,252 rpm are always equal. And an engine is most efficient near it's torque peak.

so then how did they caculate the hp with out knowing the torque?!
