I think I would run the engine at operational rpms (>5000) and watch the coolant/oil temperatures - when they got to my maximum limit, I would check the CHT reading and perhaps add 50 degrees for the limit (to start with).  If I got a lot of false alarms at that margin I would try another 50 deg.  Just a WAG.

What are we using for high temp numbers from the CHT sensors on the 13B rotary, I have the under the spark plug style sensors bolted to each rotor housing in some factory threaded holes just above the spark plugs, not really the hottest spot but the holes were already in place so I KISSed it & moved on, now I need to set my high temp warning limit & do not know what to use.  Possibly do an eng. run with upper cowl off & check bolt/sensor temp with a lazer temp gun at about 4000 RPM  & go another 50 deg. higher?  Ideas?  David R.
