Hi Guys.
Im about to install an egt guage and sensors to my airy. Its a 503 si dc. Can anybody tell me what temp it should be running at for cruise and takeoff. The same question for the cht. Any response appriciated.

No I cant RTFM because i did not get one

CHT Max 250

normal 180 to 220

EGT max 650

normal 460-580

all temps in deg C

EGT is the big one you watch while flying. It is related to the richness of the oil in the fuel

EGT High - Lean, lower oil in the fuel - bad
EGT low - Rich, higher oil content, better for cooling and lubricating the motor.

You should be able to take off at full throttle, 6400rpm and the EGT's should remain quite cool. As you tap off to cruise you could see the egt's increase as the fuel/oil leans a little. As long as they are in the normal operating zone you are safe.

You young man are a fountain of information.
