High manifold pressure and low rpm
WebMar 19, 2024 · Horsepower is torque x RPM. Reduce RPM, but maintain same torque (manifold pressure), HP goes down. Reduce torque, maintain RPM, and HP goes down. You'll find say, that 2300 RPM and 25" of MP make the same HP as 23" of MP and 2500 RPM. If it's a direct drive engine, prop RPM and engine RPM are the same.

WebMay 12, 2024 · The only regime I can think of, where a Merlin engine (supercharged) would reduce manifold pressure with increased rpm, are extremely low rpm, like idling on the runway. At these rotations, the supercharger is basically too slow to actually work.
WebAs a general rule, manifold pressure (inches) should be less than the RPM; A pilot can avoid conditions that over-stress the cylinders by being constantly aware of the RPM, especially when increasing the manifold pressure; … WebSep 22, 2024 · It is possible to make a given amount of power using high manifold absolute pressure (MAP) and low rpm or by using low MAP and high rpm. The high MAP and low rpm combination will do it with less fuel flow (i.e.; more efficiently). This would indicate that from an engine standpoint, choosing a lower rpm would be more efficient. ...
WebThis is accomplished by moving the propeller control to full low RPM/high pitch. We watch the RPM for the corresponding drop, look for the MP rise, and also watch the oil pressure gauge.
