I have been reading with interest all the chat about exhaust
temperatures.  I have included a picture of the Mazdatrix drag car
rotary on the dyno.  The exhaust headers are 1/8 steel (no, I'm not
advocating that for a/c) and they are measuring 1600 degrees downstream
at the flanges.  The pipes nearer the engine are obviously much hotter
as they are glowing red.

The caption for the picture states "Everyone hears about how hot the
rotary runs - here can see it. This was a mild power pass. Those headers
are 1/8" thick steel, and are bright red THROUGH Jet-Hot 2000 degree
coating.

The EGT probes are at the end of the headers, right before the flanges.
Exhaust temps were 1600 degrees at the probes."
 
Just wanted to forward the jpg so that we can all see just what we are
dealing with here. A failure in flight could ruin your whole day.
Keep up the good work...
