What type CHT system do you have installed…(spark plug thermocouple..?) …on what cylinder, and spark plug position…??
525-F is the limit (as you probably know) but to help reassure you.. if your baffling is in good condition, … since no adjustable cowl flaps are installed on this airplane, there is no requirement for a CHT gauge… meaning that it’s unlikely the engine installation (if proper) can exceed it’s operating limits.
I.E., new gauge installations ( replacing identical installations ) that read extraordinary would be suspect in my first thoughts. Depending upon quality, etc., a new gauge may not be calibrated…. just because it’s “new” doesn’t mean it’s “calibrated”.
Can you give a bit more info on the above?
