Is the higher allowable CHT on the new engines because of better materials, or because the construction has changed such that the reading under the spark plug has changed while the actual temperature is still the same? Just wondering.. Rob ----- Original Message ----- From: Jabiru USA Sent: Tuesday, July 15, 2008 11:01 PM Subject: RE: JabiruEngine-List: CHT's You guys need to read the manuals more carefully. Section 4 of the 3300 Installation Manual says: 4 OPERATING LIMITATIONS 4.1 RPM - Continuous: 3300 RPM / Full Throttle - Recommended Cruise: 2750 RPM - 3100 RPM 4.2 Engine Cooling Maximum Cylinder Head Temperatures measured under exhaust spark plug. Maximum Peak Temperature 200C (392F) Continuous Operation 180C (356F) That would indicate that the red line would be at 392 degrees F. The green would be below 356 degrees F and the yellow would be the area between 356 and 392. Those numbers are for the new hydraulic lifter engines. Earlier engines had a max of 347 F.

The JAR22H engine testing proved it very well - 50 hours at 400 F at full power. No problems.
