Yeah, it does seem kinda extreme at 2 am (I am scheduled to start day shift for a while on July 13, so not so many late nights as evening shift provides). However, other than my rotary being MUCH quieter with the turbo installed, Ellington Field (EFD ), a former Air Force Base and current home to the National Guard and NASA, with the Civil Hangars located well, well away from any homes. The field is a routine stop for Military Aircraft in their cross country trips and corporate jets coming and going at ALL hours. While the rotary makes noise, it does not touch an afterburner take-off (in fairness, I only have observed this once late at night), but jets come and go throughout the night. FWIW .

Chris,

Ironic that the subject line is quiet..... I daresay, it wasn’t quiet in the Houston area at 2AM when you ran up your engine to 6300!! I'd probably end up waking half the population of suburban San Diego if I did that.

Glad you are making progress. I'm not making any. Summer is the peak of the soaring season and RV/rotary stuff takes a distant back seat to glider tweaking/flying.

I am such a rotary geek....but I really dislike the list being this quiet. I am a junkie to this place.

Anyway, I have been making progress....since I am not going to Osh. Next year, surely....one year I will be right?????

I made brackets for and secured my intercooler under my engine. I also made a plenum to the intercooler to direct air and secured some scat and ceet hoses to it.

I also wired in some temperature activated switches for the oil and coolant fans.

The fuel return hose was originally a long return line to the cool side of the engine, routed under the engine. I do not remember why we chose this route, however, I re-did all of this to a much, much more direct and hopefully better set up.

I couldn't wait to go and start it again. I broke one of the cardinal rules of homebuilding by changing more than one thing at a time. HOWEVER, I pushed her out of the hangar and low and behold she started right up and ran smooth just like it did a week or two again. Wahoo (tentatively). Ran her up to 6300 rpm at 34 MP with the prop full fine (45 degrees if IIRC ) on the IVO . Those temps really sore at WOT but was able to keep it up for a short bit...it was "only" 80 degrees out (about 2 am in Houston). As I have stated, it will idle all day long, even at 100 OAT and stays pretty cool, but goes up fast with power.

I hope to get out there most the day (hopefully) tomorrow. This was fun....even if not at Osh.

I think many folks are busily mission planning their flight to OSH this year...

I sadly have no time to work on my 9A project since I am swimming pool and landscaping boy this summer...can't wait til winter again!
