CHTs - What is acceptable?

Nobody here can give you the correct CHT for your aircraft.
The engine manufacturer can, although it's like pulling teeth trying to
get it.

As a general rule, if you hold climbout to a max of 380CHT/1425 EGT and
cruise max at 350 CHT/1380EGT you won't seize or damage anything - that
is not to say that you will be at your most efficient - only that you
won't damage anything.

The most knowledgeable people I have found on this topic are Advance
Pilot Seminars. Walter Atkinson is one of their instructors and he is
often available at Cessna Owner Organization Forums.
I learned more about this subject from him than anyone else.
He teaches ROP leaning on carbs and LOP leaning on Gamis.
He really knows his subject and is the person that I recommend to answer
your question.

What is an acceptable CHT in cruise? How hot can one stay in extended cruise
flight? I've got 6 new ones and want to take care of them.


Thanks in advance.
