From what I understand... that's actually the same thing as he said previously... since you usually get torque at lower rpm, and horsepower at higher (HP = Torque * revolutions per minute * conversion factor)

Aha! I love physics!

You're right, In the above equation, HP is directly proportional to torque. As torque is increased, so is HP given a constant rpm. But if HP stays the same and torque increases, rpms must drop to compensate...therefore torque increase will be found lower on the powerband. If HP increases, and torque stays the same, rpms must increase, thus making the HP gain higher in the powerband.
