Jos,

This is exactly what the constant speed propeller does.  Just set the MAP 
with the throttle and the RPM with the propeller controller.  When Cliff 
said he was flying with a low MAP and 5000 RPM, his engine is developing a 
certain percentage of power with low torque.  The same power setting can be 
had with a higher MAP and lower RPM but with more torque.  The combinations 
are almost endless.

Kingsley in Oz.
