Is that 100mm measured 1. "on the side of the pipe" 2. "on the outside curve of the pipe" 3. "on the inside curve of the pipe" ? ...or does it matter? Or should I just be consistent from pipe to pipe? Thanks, Mike -------- Mike Miller @ millrml@aol.com 601 XL-B, 3300, Dynon Remember, "the second mouse gets the cheese"!

HOPEFULLY the EGT should read 1202 F (HA!) to 1382 F (HA!). In reality what you want to do is have the probe located the SAME distance down from the flange. Do NOT put the probe in a curve of the pipe. ALWAYS TRY to keep all probes as close to the same setup as possible. When reading the temps... DO NOT set in cement reading between other planes. When you read your TEMPS you are LQQKing for what is normal for your plane and CHANGES to that NORMAL. The CLOSER to the flange the higher the temps. The further away the lower the temps. Probes on a bend ... WHO KNOWS! If you read the installation instructions from the Gage Manufacture use their recommendation. YES - your reading may be different. BUT! As stated before... ALL reading are ONLY a NORM for YOUR PLANE. YRMV It is BETTER to go further down than too close. But what is too close? Why? Too close you will shorten the life of the probe. Higher Heat. E.I. recommends 2.5" Down JPI if I recall is the same. I know, now you are really confused. AND don't Lose Your Head Below the Window.
