65% is 65%, is 65%. All equal, no harder. That is the point of turbo
norm. The engine has not got a clue how high it is. MP is the same at
sea
level or 15 thousand.

The only argument is the temp. Keep it cool. it is not that hard, nor
is
it rocket science.

Yes the MP is the same but the CHTs will be much higher. Basically you
are
trading better performance for higher temps. Turbo Lances can't make 75%
power above 16,000 on warm days without CHTs well over 400F. It really
isn't possible to produce a lot of power at high altitude without higher
temps. I think that Robert's point is that there is a tradeoff.

Well, it's wrong. My CHT's are virtually the same (370-380) at 8000 as
they
are at 16K.

Heat come from your mixture, and at higher altitude, there is less drag to
be overcome.

All things being equal the temperatures will be higher at higher altitudes.
It is a simple fact that less dense air does not cool as well. I'm not sure
what you are trying to say about less drag unless it is to point out the TAS
advantage of higher altitudes.
