So we flew back from Midland yesterday. Flew out around 9am when it was a pleasant 97 degrees F. Density Altitude at the time of departure was around 5,500+ ft. I fought high CHT's all the way up to my cruising altitude of 7000' MSL. I really wanted to go to 9000', but I was having trouble keeping the CHT's at 400 degrees on 3-4 cylinders. I could have made 9000, but it would have been at a painfully slow rate of climb and was just not worth it.
What do you guys see on climb out in the desert southwest in regard to CHT's? I have a 114B so I have some cooling issues that are probably not there with some of the early models that have two cowl flaps and larger cooling intakes on the nose.
Once I got to cruise I got the CHT's down to a manageable level (350-370 with a delta of 20 degrees).
What was the OAT at 7000'?
