It is best to place a flap at the exit of the cowl/radiator duct.
Placing an obstruction in the front destroys dynamic pressure. An we
need to recover as much pressure as we can to persuade the air to flow
across the rad core.
A carefully designed diffuser is key.
Having a large hole with partly covered radiators inside, is like having
a deployed air-brake.
And we don't need a permanent air-brake, do we ?
