In fact, the owners of high output diesels (in pickup trucks)
generally are told "Do not exceed 1,300° F under any conditions, and
run below 1,000° F if you want your engine to last." Often aircraft
engines run below 600° C for just that reason, aluminum alloys
degrade above 1,000° F and that is not good for aluminum heads! CHT
is usually MUCH lower than EGT, but at or near valve seats, it is
higher than where CHT is normally gauged.<br>
<br>
Remember, this advice is often very conservative so the warranty is
cheaper. Also, losing an engine at the wrong time in an aircraft is
not a good thing!<br>
<br>
Ahead of a turbocharger the EGT is usually higher than after it.<br>
