Whichever one you choose, I am most interested in where you mount the
beast, than what size tube you choose. You can't put it in a position
where rocks and debris might hit it, which doesn't leave many options. I
think you would do better with the setup from bus boys and put the cooler
above the transmission, as someone recently posted having done.

My 81 air cooled will reach 230 easily on a 93 degree day, and in fact, it
has sat totally useless in my garage for the last few weeks as the temps
here in Utah are exceeding 100 degrees. As much as I love the van, I have
to admit, its of no use in the heat. A thirty minute drive down the 6 lane
concrete freeway, and the temp gauge (in the drain plug) leaps to 250 and
beyond.

I really would like to add the aux cooler, but I am not sure it would be
much help in this weather.

John
