If I want to keep my CHTs less than 380, I have three options:
1) ROP by nearly 200 degrees, for a fuel flow of about 17-18gph at 4500’.
2) LOP by nearly 100 degrees, for a fuel flow of about 11.5gph at 4500’.
3) Partial cowl flaps.
Yes, I’ve checked the baffles. I have GAMIs, with a spread of 0.2. Takeoff fuel flow is fine. The situation is mildly worse at lower RPM.
Other solutions?
I’m looking into the cowl louver STC, but the Skywagon club owns it and they aren’t selling it right now because of some “pending paperwork.” Even with the STC in hand, I’d have to find the louvers somewhere. Word on the street is this STC is good for “only 10-15 degrees,” but that’s all I need.
What if I got the louvers from a Bonanza and put them in the Cessna cowl? Does that sound field-approvable? I don’t get how anyone in a NA engine gets 100 LOP! When the last cylinder to go over the peak with my IO-540 happens (about 5-10 LOP) I stop leaning, and my GAMI spread is about 0.3. My CHT’s are mid to low 300’s at that setting and FF around 10.7 gph. Murray

Are you saying that you have not read an Aviation Magazine in the last 50 years?  I was instructing at the same school (Sussex Aero)in 1970 where he was instructing , and he was writing for Air Progress then... now he has articles in EAA Sport Aviation, AOPA Pilot, General Aviation news, Flight Journal... etc.. He partnered in a new S2 in late 70 or 71. http://www.airbum.com/Pitts/PittsFlightTraining.htmlHere is an article on the thread topic... by Budd.. http://www.airbum.com/pireps/PirepCessna185.htmlIf he isn’t on BeechTalk I don’t know him

Quote: If he isn’t on BeechTalk I don’t know him That is about true. If there had been an internet in my early years of flying, I probably would not have digested every aviation rag out there.

Hi Daryl, I must have a sister ship to yours, CGDIP sn 3971. Stuart, I do have the cowl louvers. They do help for cooling but on floats I leave the cowl flaps open or I have one cylinder peaking over 400F. Username Protected wrote: This winter. Landing at Lac La Biche Ice Runway.

Why can’t you put autopilot on the 185? You just have to manage the trim manually.
