Maybe you mean that the two main things that affect hp output (rpm and throttle opening) result in less than, or peak hp for the engine. Well, YES. Peak horsepower on an rpm curve is the standard output of the DYNO. But peak hp for the engine actually does not change. For instance, you can obtain higher torque to climb a steep hill by shifting to a low gear. Seems like higher hp, but the same amount of work is being done...I mean, The overall kWatts of power is the same as pushing the bike through the air at 75mph. That's horse power. Torque is a MECHANICAL ADVANTAGE, but you expend the same amount of kW (hp). Got to admit, your argument sounds like AI generated. No real intuition.

There is a point where gearing is optimized, and you can't get past. In most cases, ho to the wheel is lower than in that optimized state. It's when the engine peak output and the load balances one another out where the engine does no longer accelerate, or rpm no longer increases. On a dyno, rpm increases past peak HP, because the load isn't realistic. Hence you'll get different HP ratings from dynos with heavier or lighter rollers. All the math on this forum doesn't take that into consideration. It only takes into consideration when engine output is measured on a single load (single dyno). Not on a variable load, which is what happens when you accelerate, and wind resistance becomes higher at higher speeds, and prevents the bike to go faster. |

Can't interpret your post. You really seem to think that the optimum output of an engine in kW or hp changes. Bottom line is in fact that the engine can't make more.
As I stated, "Torque is a MECHANICAL ADVANTAGE, but you expend the same amount of kW (hp)". Just because a geared down engine can lift a 3 ton pallette doesn't mean that the 20hp engine in the forklift makes more than 20hp. You are just not thinking. It is still 20 hp. Work includes a distance meaurement and time factor. Maybe you are missing this? 70mph pushing through the wind (more than a mile per minute, where wind provides constant friction), or lifting a truck at 3 inches per minute, against gravity. It is still 20 hp (14.914 kW).
