Hi! Kingsley/all
That is probably why Jabiru "cocked a deaf ear" when I was trying to
find an economical power setting on my 3300/MT CS Prop combination.
All they needed to do was a Dyno run with a few differing RPM's and MAP
settings on differing ambient pressure days to provide some power output
comparison graphs. I'm still waiting but I suspect that the ultimate
power truth would have then been plain for all to see!
Perhaps they wish that I'd been holding my breath all this time !!!!!

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.
