I tried a Callies water to oil exchanger in the race car. It worked fine. It
made the oil temp and water temp the same. Unfortunately they were the same
at 200 degrees.
That with a Griffen aluminum radiator 19"X31"X two rows. The 200 degree oil
was OK but 200 degree water is not. It was also very heavy. I cut it open and
recovered the air/oil cooler and it now cools the transmission oil.
