Childs play!  On the Moller rotary we had EGTs of up to 2100 deg.  The
exhaust system would glow bright orange all the way to the end which was a
5" supertrapp with like 30 discs.  That sucker shot a ring of blue flame
out of every disc slot all the way until the flames impacted a 10" diameter
1/4" wall collection bell that exhausted out of the dyno cell.  The bell
was welded to an 8" dia. 1/4" wall tube that ran up along the ceiling to
the exhaust fan suction side.  It would draw in plenty of cool air in the
bell to mix with the exhaust.  That sucker would glow dull red for 5 feet
down from the bell even with secondary air flow.  The heat in the cell was
so intense that the light fixtures began to drip!  The .035 stainless pipes
got so hot near the ports that they had no color at all and appeared to be
translucent.  I've since had others tell me they have experienced the same
perception when looking at pipes *that hot*.  Needless to say our BSFC's
were not the greatest at this operating point.

Yup!  I have seen the inside of a Borla muffler without even taking it
apart.  Pretty spooky!
