I need a general concenses on EGT probes. I am putting a Corvair in my XL and I am wondering if I should go with 6 EGT probes or just one on each manifold? I belive 6 would give me better detection of a problem in a specific cylinder, but one probe in the right place would also detect a problem on one side of the engine. What do you think?

WW has this answer in his archives-( he says in so many words: why have 6 when a lot of production aircraft have none)-------- I'm going with one on each side.

Hi, Larry.
I, too, wanted to use 6 egt probes on the Corvair. But upon looking at the exhaust manifold, there jus ain't enough room to do it properly with the quick radius bend. So I'm settling for one on each side. So I'll have dual CHT, and dual EGT. Should be enough.
Best,
Rick Lindstrom

My plane only has one EGT gauge. It is used primarily as a baseline for
leaning. I think many people go overboard when they are getting guages for
their engine. I didn't.

To me it all depends on why. If you are installing an engine monitor or FADEC on your Corvair then the only way to go is with the six probes. Mounting them sounds like it can be fun. If you're only planning on gauges you're going to need a big panel to mount at least three double gauges. Why bother? You won't have time to read them any way. Sight differences in the gauges will worry you half to death when you should be flying the plane
So if it's going to be gauges I would locate the hottest cylinder with a laser thermometer and use that cylinder for CHT and run a dual EGT, one from each manifold. I'll bet that if you check with the guys on the list if there is one cylinder, in the back which will usually run hotter than the others.
