"that picture above is mis-labeled, it makes little to no sense that it would have that 11 blade 911 fan , which is used to aircooled the cyclinder heads, and the water pump...which implied wate to cool the heads...."
Facey,
I suspect that engine has air-cooled cylinders and twin cam water-cooled heads.
Does kinda seem like overkill, though, don't it?
