What is the preferred installation location for the EGT probes on a  Lycoming O-360 engine?  How far down from the exhaust attachment yields the  proper temp?  It's a RV-6A if that matters.  Tnx.

EI recommends 1.5 in down from flange. Some have a small hole the flange 

there..mine did, so drilled it on through and has worked well so 

far...but don't have that many hours on the probes yet, so don't know 

how well they will last. My old single probe was installed about 3 in 

down...welded that up.

Don't know what JPI suggests. I have the UBG16 with fast response probes.

 Hi Rick!

 There is no 'proper' temp for EGT.  Even slight differences in orientation around the exhause stack or down it;s length will cause the readings to change.  What you're looking for is a relative change as you lean, not a specific 'goal'.

 

 Closer to the flange the hotter the reading will be, and of course the further away the cooler.  However, try and keep the probes in the same spot for each header, as best you can.  You also want to orient the probes so that they don't interfere with anything else running close ... like the cowl or oil/fuel / tubing etc.

The main thing is to have them all at  the same distance since EGTs are

 not an absolute number like CHT.   You may find that the front right

 tube determines the maximum if all are  horizontal when installed.  But even

 that depends on your exhaust  system.

  

 My recollection of mine is 1-4 inches  but that is not verified.  I put mine

 as far from the flange as I could and  the most distant was maybe 2-2.5 inches 

 before a bend in the exhaust would  cause orientation issues.

Hi All-



Another point to ponder is that the further from the cylinder the probes are, the longer they are liable to last.  As with everything we do in this field, it's all a trade off.
