This isnt the very well beaten to death Air cooled Radial engine vs Water cooled V engine question. I was wondering about the differences between the 2 types of engines oil cooling systems. Did a radial engine have a larger oil radiator and therefore a larger oil capacity or was it the...

Could the use of forced cooling, ala BMW 801, have permitted air-cooled inline engine types such as those manufactured by Ranger and Argus to potentially achieve power levels and reliability of their water cooled inline cousins, or air cooled radial cousins? Just to be clear, I'm not...

Can modern air cooled inline engines compete with the water cooled engines of WWII? Perhaps there are no modern engines of those ratings being produced, if that is the case, then could modern air cooled technology produce engines competitive with water cooled engines of WWII?
