Additionally, the chart that TT provided us with is not a really good example because that engine produces about the same hp from 2100 on up. A more typical NA engine would not have the flat area at the upper end of the curve. If TT were to overprop to where his new red line is, and limit his RPM to that point (usually reseting the stop on the pump) he would, in his case be giving up very little HP because the curve is so flat at that point.
