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.

Subject: [FlyRotary] EM2 CHT ?
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. Cook RV6A Rotary
