OK, do you have a picture?

I'll have to drill through both outer and inner parts of the manifold. And the inside of the manifold appears designed to "float".

Finn,

 

You should be able to locate the EGT probe about 0.75-1" out for Rotor 2. Bottom or prop side of the tube. Match Rotor 1 location to rotor 2. Adjust mixture to keep EGT’s below 1650F. I target below 1600F but see 1650F if I’m not paying attention. Formula renesis race engines are running below 1600F with F/A in the 13’s. I have not been able to achieve EGT’s that low in the 13’s. I have to run richer at high power to keep EGT’s around 1600F.

Engine builders like different locations. The object of the probe is to collect data on the combustion process inside the chamber. So, the ideal power mixture is the highest temperature in general the same as a piston engine. (It was running great just before the piston melted) So, more fuel or less fuel than best power can both lower exhaust temps. So, one way or the other (pick one) keep EGTs below 1650 and the probes last a long time. Stock apex seals last longer as well. So the EGT gauge is nice to have rather than trying to get chunks of apex seal out of a muffler. Even if you run ceramic apex seals which will stand up to anything, however the exhaust system (even stainless) will have a short life above 1700 degrees. I melted everything there is to melt on the racer. I was a slow learner.
