Rotarians,
When I installed my T04 turbo I must have = damaged=20 the EGT probe. I was
seeing 500F on take-off. Today I installed a = new=20 probe and it looks like
the new turbo runs a lot hotter than the = old one.=20 While installing the
new probe I noticed that the ceramic coating = on the=20 turbo had turned to
dust.

On take-off today I saw 1730 and = the EGT=20 alarm went off. I backed off
the throttle and flew with it down = around=20 1600, but that only gets me
around 4500 rpm and zero boost. Bring = it up to=20 5000 rpm and I see 1650.
This is with the mixture a little higher = than mid=20 scale. Richen the
mixture a tad and I can reduce EGT by 30 F or = so. If I=20 bring the rpm up
to 5300 the EGT is up to 1700 pretty quickly. Oil = and=20 coolant temps are
fine at around 180 - 190. I put 3.3 hours on the = plane=20 today with no
other issues, but at 4500 rpm I don't get there very = fast.=20 :(

What do other rotary flyers consider max EGT, and what could = be=20 causing
it to be so high (if this is really=20 high)?
