My engine is a C90. My normal CHT for the hottest cylinder normally runs between 375 and 425 indicated. On climb out to 4000-6000 feet I sometimes indicate as much as 500 in the summer, and once this is reached I usually slow the climb a bit. I have been told by both Alcor (the maker of my guage) and by my I/A that the type probe I have reads as much as 50 degrees higher than the actual cylinder head temp. Therefore my actual temps probably run 30 degrees or so less. Craig Helm '70 M10 N9512V Graham, TX (E15) Neill Carnahan wrote: > What is normal cht ?
