Is this the final answer to the original question? If so, I can understand why the confusion then. Its hard for me even to know why there is more friction simply because there is more power. I've just taken it for granted from what people have told me.


That's a simplified version of the real answer.

Yes it is always a percentage. However as the power level increases the percentage will decrease slightly.

So it may be 17-18% at 200HP but only 15-16% at 400HP. (random numbers to show my explanation)

It's not that the powertrain gets any more efficient but the amount of parasitic loss will not grow in a direct proportion to the power gain.


Either way it's all like I originally stated. "For Bench Racing" crank numbers.
A close guesstimate is good enough for bench racing and the only numbers that truly matter are what is getting to the ground.
