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. WebCessna defines bootstrapping as "The unstable manifold pressure condition that occurs when the wastegate closes at high altitude under low RPM operation." In other words, it is the point that the manifold pressure begins to fall off when the RPM is reduced.
