I would be interested to know what speed folk are using to climb. I am finding that once the speed drops below 100mph the cooling drops away quite abruptly.
My theory is that below 100 the nose starts to come up and the pressure increases on the cooling exit due to the increased AoA.
My oil temps sit quite low most of the time, normal flying 155/160F. (Yes, I need to reduce the air flo to the oil cooler.) The only time the oil temp gets near 170/180 is in the circuit when the CHT are dropping right away and the manifold is back at 12/15" but the flaps are out and I am trying to get the speed off.
Is this familiar to other -4 owners?
