The EGT's seem to be getting higher all the time. At WOT today (peak
power mixture)and 5500 feet, turned 5800 rpm for a TAS (best I can
calculate with data available) of 190 mph and 9 gph. The rotor 2 EGT was
indicating 1826 degrees F. Oil temp was 178 and the water was 208.
Supposedly the high water temp would help efficiency, but hurt power. Am
not sure why the high water temp would hurt power?? The OAT was
indicating 81 degrees. The water pressure is running about 16 psig so do
not think I am close to boiling and Tracy does not think 212 would hurt
the engine. Anyone else got any ideas about 200+ water temps.
At 8500 , the OAT was 10 degrees cooler.Max RPM was 5750 and EGT was
1775. TAS was 186mph.
Rusty, my MP was 29.7 at start of roll and baro was about 30.0
Bernie, Sorry Ed guess that you will have to represent the rotary crowd
which you will do a super job
Sorry to hear you won't make it, Bernie. The crowd needs to see new faces{:>)
Sounds like to me you are doing OK although 1826F seems a bit high on EGT - but that could be probes/location, etc.
I have hit 240F coolant (never for long) and have sustained 220F for 10 minutes or more. I am comfortable with anything below 210F on coolant as long as the oil temp is below 200F. Sounds like a great TAS for 9 GPH.
Hope to see you at Charlies
