109 prop pitch (rpm) and the supercharger

Ok..

Your point is wrong.

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

Ok..

So we have

JtD pointing out that a change in engine RPM will result in an change in prop RPM

And we have a conflict between what Crumpp and Steinhilper are saying, i.e.

Steinhilper saying change the RPM
Crumpp saying maintain the RPM

Thus the only thing left is to decide who do you want to belive

Crumpp or Steinhilper
