When I did my peak monitoring, I noticed that peak EGT temps went down slightly as altitude increased.
For the sake of aurgument, let's say cylinder #1 peaked at 1,400F at 8,000 feet. At 12,000 it peaked at 1,375.
If you want to run 50 LOP at 12,000 feet, should you run it at 1,325F or should you use the highest peak that was measured and run it at 1,350F?
Theoretically, at a higher altitudes peak EGT could be what at 8,000 was 50 degrees below peak. Should that peak temp be considered a static or dynamic number? If it is a static number then at any altitude above 8,000 feet, you would set the engine at a lean mixture setting where it runs best and the EGT did not exceed 1,350 degrees.
My reason for asking is from a metalurgical standpoint, the hottest peak EGT the engine would see at or above 8,000 feet would be 1,400 degrees.
