Rotarians,
When I installed my T04 turbo I must have damaged the EGT probe. I was seeing 500F on take-off. Today I installed a new probe and it looks like the new turbo runs a lot hotter than the old one. While installing the new probe I noticed that the ceramic coating on the turbo had turned to dust.

On take-off today I saw 1730 and the EGT alarm went off. I backed off the throttle and flew with it down around 1600, but that only gets me around 4500 rpm and zero boost. Bring it up to 5000 rpm and I see 1650. This is with the mixture a little higher than mid scale. Richen the mixture a tad and I can reduce EGT by 30 F or so. If I bring the rpm up to 5300 the EGT is up to 1700 pretty quickly. Oil and coolant temps are fine at around 180 - 190. I put 3.3 hours on the plane today with no other issues, but at 4500 rpm I don't get there very fast. :(

What do other rotary flyers consider max EGT, and what could be causing it to be so high (if this is really high)?
