I'm curious what the max safe EGT is on an M278, reading from the oem PID.
In my tinkering my EGT at full load is usually ~1050-1250F, mostly because I can't lean on it for very long. There was a couple times it exceeded 1300 while floored for >5 seconds. It makes me worry that if it had been a 1/4 mile run or worse, if it would continue to climb. So what temp is too much?
I looked at some runs that others posted, which is slim pickins, plus most people don't add EGT, but an M156 hit 1660 stock, then 1780 tuned, but all the M278 engines were ~1250-1320.
Is the EGT sensor before the turbo? Seems like it must be, but I have no clue where it is.
