Efficiency is always a factor. The more efficient airflow in and out of an engine, the more power, be it torque or HP, it will make.

All engines dynoed will have the torque and HP curve cross at 5250 rpm. It has
nothing to do with efficiency. It is simply a function of the equation used to
derive HP from the torque figures that a dynomometer measures.
Thunderstruck...

Torque is more important than HP. Torque is what makes it move. In a nut shell
, Torque is the low RPM rating and HP is the upper RPM rating. when they cross,
that's the maximum efficiency of the engine. I've seen engines on the dyno ha
ve two crosspoints. It's real weird to see a dyno computer produce torque and h
p ratings like that of a 1200 ci cummins in a Kenworth KW600 on a 3.9L or 5.2L.
