ok 109. my mistake.
Comparing water cooled inline engine planes to air cooled radial engines all different planes with different designs and cooling efficiencies modeled. It was already pointed out in this thread that oil temp is function of "oil in" and "oil out" and those functions are all dependent on map pressure, rpms, fuel mixtures, airspeeds and radiator/cowling positions (open, partially opened or closed) and for water cooled engines would be dependent on efficiency of the in/out of the water temps (so if you take a bullet damage there you should be more prone to overheat!) and air-cooled on the heat exchangers/oil sump/pump and don't forget the ambient temp of the map. If your able to capture all those dynamic functions in a stop watch run and draw a reasonable conclusion???
