The engine owner manual sez :

> Normal operating temperature approx 75-110 C.
In my understanding, 75C can be considered as the minimum operating temp.
The green arc on our CHT gauge is therefore 75-110, et we ensure the
temps stay within those values in flight.

We built a proper radiator duct and cowl flap, so keeping the temps
within the green range is easy.
As I mentioned, some just blank part of their radiator. But then the
drag is always high.
