W8ye: I have run a few pusher installations over the years , the last was with a ST 61 ringed engine on a plane called a "Nosey". I feel that as long as the engine cylinder is exposed there is not a cooling problem with a pusher engine . Don`t seem to make any difference if the air is pushed or pulled over the engine ,it`s about the same. Once worked with a "Old" Msgt. that was crew chief on the Bell Airacuda ,twin pusher that they had to tow to end of the runway before starting engines! They over heated that bad, but they were liquid cooled. More of my rattling on,sorry.
