Well when we are talking peak horsepower that occurs at a fixed rpm that is independent of how long it took to get to that engine speed/rpm.
Now if peak horsepower shifted from say 5800 rpm to 6300 rpm, then that could incur more losses because now we are talking different/faster engine speeds when comparing before and after peak horsepower ratings.
But that is all the more reason why you can't try to figure out what power an engine is making based on rwhp or dyno results, and try to make any meaningful claims from it.
