EGT

EGT: Max. 950 °C (1742 °F)

The exhaust gas temperature (EGT) on a Rotax 912 series of engines with both ignition circuits active should read 1470 degrees F (800 degrees C) and should not exceed 1560 degrees F (850 degrees C) .

These readings should be taken by EGT probes located 2.76 inches  (70 mm) down stream of the exhaust flange.

The back pressure at takeoff should be 2.9 psi or 0.2 bar

Idle EGT depends on rpm, fuel and location of fresh air /cooling air hit the engine. In puller case and pusher case is also depends on EGT.

but keep eyes on Maximum range for engine safety and healthy life.

Hi Xing,

Where did you see 70mm or 2.76 inches?

I saw the same on Google.
