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've had server issues this week and could not send this until today.

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.
