WebJul 22, 2015 · That means that the valve timing and camshaft profiles were made in such a way that your engine "breathes" best between those speeds. That's why you have the most torque in that region. Another thing is that as the RPM increases, it gets harder and harder to get the optimal amount of air and fuel into the cylinder AND burn it at the optimal rate.
