Didn't read the whole thread, so sorry if its been mentioned. It is a huge problem for any jug driver.

Its turbo-supercharged, a large exhaust driven turbocharger behind the cockpit delivers air to the intake manifold, that's why the jug is shaped the way it is. Notice in the cockpit the gauge marked "turbo rpm", that is the RPM of the turbocharger turbine supplying forced air to to the engine.
The system is designed to hold a certain manifold pressure constant for a wide range of altitude, i.e you set your manifold pressure via your throttle, and the turbo-supercharger automatically adjusts the amount of forced air going into the engine to hold that pressure constant. Its a genius system, because a P-47 can hold sea level like manifold pressure at very high altitudes.
