If you could set up a prop and environmental conditions that allowed you to run full throttle at sea level on a standard day at 2575 RPM you might get 93 HP, but how often does one do that? Any change in conditions (other than going below sea level or exceeding red line) will result in less power. Most of the time you are climbing at RPM considerably below red line or cruising at throttle settings less than full, so the power levels are lower. John
