I am getting ready to drill holes for the Dynon EGT probes in my Vetterman dual muffler exhaust.
In reading, I have learned the following:
1) Clock them any way that works for you, but keep them the same distance
2) Don't put them on a bend
3) The closer to the engine, the more responsive the readings will be
4) Too close to the engine, and you will burn them up
5) Too far from the engine, and they will be slow to register changes
6) Ideal distances for a Lycoming are in the 2 1/2" to 4" range
Can anyone tell me why rule #2 is true? Is it because the hose clamp won't conform, or because it will bite harder on the edges on a corner and risk a crack, or because the gas does different things around a bend, or something else?
The reason I ask is I can get a 2" distance at best given my pipes. I would prefer 2 1/2" or 3". But one of the pipes starts a 45-degree bend at about the 2 1/4" mark.
If I put the probe at 2 1/2", it would just be at the start of the bend. Would that work, or am I asking for trouble?
