109 prop pitch (rpm) and the supercharger

[Crumpp]

Geez robo,

Quit being dense on this, I have explained how it works. What I am saying is what the pilots are doing.

that it's not all about setting your engine for certain (optimal) rpm and keeping it that way

Your point is wrong.

To mainatin speed / performance.

Right...by maintain rpm!!!!!

If you lived close by, I would take you and show you how it all works. My plane has a very accurate Engine Monitoring System.

Manifold pressure, rpm, and mixture are all interelated to produce a given performance.
