I understand that the equation gives you an approximation, but Manifold Pressure plays a bigger part in power than does RPM, does it not? For example, to get 75% power, the number 48 assumes 24 squared, I guess. However, if you increase RPM to 2700 and reduce MAP to 21”, the number 48 does not yield 75% power. Likewise, 30” of MAP and 1800RPM would likely yield more than 75% power (while not advisable to fly that far over squared. Is there an equation somewhere that gives a weightingvto RPM & MAP that are more true to life than the even weighting?
