Montblack,
The reason its called a 231 is because it is suppose to cruise at
231mph (I believe that is wide open throttle though).

The late model Mooneys (201, 231, 252) are definitely named by their
top speed in mph.

Here is a link to the performance section of the 231 POH.

It appears that 231mph is achievable at approx 40" & 2700RPM, which
the turbo'd engine can achieve at 16k through 20k pressure altitude.

I doubt anyone would be willing to run the engine that hard as it is
very close to 100% power.

75% @ 20k ~= 220mph
75% @ 24k ~= 229mph


Let's see: % of HP = GPH * 14.9, so figure what the power level.

It doesn't so much matter where the throttle is set (WOT works best), it's
the RPM (seondary) and the fuel flow (mixture) which is primary.

For example, in a 310HP engine, burning 14.5gph, you would be at 70% power.
