Adam,

Good numbers! My results on the inline 4 with diesel pan and sound shield are
very similar ... 35 to 50 F. I have also found reductions in cylinder head
temperatures, but I can't recall the numbers. I put it in the archives at the
time. Yes (for the nonbelievers) cylinder head temperatures follow oil
temperatures even in water-cooled engines (just not so large a delta).

I also agree that the oil cooler is one of the best lifetime and reliability
mods that can be made to these vehicles - even more important for the air
cooled culture!

BTW, I am using the RX7 cooler now, but am switching to the Audi 5000T oil
cooler(s) for the turbocharged Audi. I have also mounted the oil cooler (RX7)
above the trans with muffin tin fan cooling. But for the Audi install, I'm
going to mount the Audi coolers with puller fan underneath the right rear
battery area. Opening to access air from the side vent.
