i really doubt that its modeled correctly right now.
i reach the same top speed with rads fully opened on deck like i do with rads almost closed.
but of course too high temperatures will kill your engine.

Of course, not good. I read, if the pilot need to air-braking, often opened the radiator instead of flap because they handled it more quickly. This behavior occurred between the half and full opening stage strongly...
