Stan,

As you know I have one together with a remote oil filter setup, but my
installation is more of the water-cooled inline 4 variety! For some
air-cooled comment though, in my pre-Vanagon days, I mounted a huge oil
cooler (aircraft surplus) (18 inches x 16 inches by 1.75 inches) on the
underside of my '72 Safare hightop camper. I plumbed it between the frame
rails (not the center section) and made a pair of aluminum scoops mounted on
the top and bottom of the cooler. The cooler was mounted parallel to the
floor with the top scoop outlet pointed to the  rear, and the bottom scoop
opening directed forward. I initially set it up for the AC VW engine (dropped
top speed a bit with additional drag!). I then kept both it and the factory
cooler on the Corvair 140 HP engine I put in to replace the VW. I wasn't
monitoring oil temperatures well, but noted very significant CHT drops, and
the oil lost its burnt aroma.
