You just made my argument. Go to the point on the chart where the PRODUCT of RPM, times torque, is the greatest.
For this chart it is about 3200 RPM just like you said. Torque dropped off slowly up until that point, but the rise in RPM meant the product of RPM and torque continued to increase.
If torque only drops slowly as RPM increases. POWER goes up. Because POWER is the product of RPM and Torque.
You notice I don't argue with the term power. Just HP. That is because HP is only a salesman pitch.
For instance, tell me the size of the horses Watt used to come up with his constant of 5252? Were they Shetland Pony's or Clydesdales?
It's fine to compare an engine using Power as long as you understand that power is just a product of torque and RPM.
HP=RPM*torque/5252
