I am installing 2 Air conditioning heat exchangers in a Lancair 235 with a
Mazda rotary engine to be used as radiators.
These things are approximately 9"x14"x4" thick and have about 26 sq. ft. of
heat exchange surface each.  Also they normally operate in air conditioners
at up to 300 PSI.
Look at Tracy Crook's RV4.

Hank, 
You may have trouble getting air to flow through them at low climb airspeeds.
What kind of car did they come from? I will buy one and test it
with a squirrel cage blower I use to test rad cores and compare it
with other cores I have for pressure drop.
