How rich are you running? If it's
really rich, you may have fuel burning in the exhaust even if
timing is correct. Can you lean at near full power & get a
drop in egt without a significant loss of power?
Also, even conventional a/c engines see egt's all over the map
from engine to engine, due to timing, mixture, and even position
of the probes (distance from port, exposure to exhaust stream,
etc) and variation in the probes themselves.
Of course, with the P-port engine, you might just be making more
power. :-)

Dennis,
I have a P ported renesis and am seeing EGT
up to 1850. Having talked with various people with far more
knowledge than myself, who suggest it may be that the spark
should be advanced up to around 30 BTDC. to reduce the EGT.
Rather than destroy the motor finding out, I am looking at
getting the engine onto a dyno to clarify the timing and
EGT’s. Should be very interesting to say the least. No one
works here until the first half of Jan has passed in this
banana republic of OZ.

I actually have the
RD1-C PSRU. (My Bad.) Tracy started selling these
about 6-7 years ago for use with the Renesis.
The prop turns
clockwise from the pilot's seat view.
I normally see EGT's
in the high 1750 F. during full power takeoff and
early climb. It will go above 1800 F. if the
mixture is real close to best power. I have my
EM-2 set to warn me if the EGTs go above 1800.
