I would have to work to get my CHT's anywhere near 400.


What do you see routinely during cruise?

I have the factory instruments, no engine monitor. This afternoon I
flew up to check out some bird hunting grounds near the Canadian border.
At 9500, wide open throttle and 2500 I was getting CHT's at 300
degrees. OAT was 40F. On the way back we flew at between 3 and 4
thousand. 24 inches and 2500 rpm, a little over 74%. I was seeing 350F
on the CHT at an OAT of 70F. I was about 30-40 LOP the whole way back,
burning 14 GPH, indicating 175-177 mph.
