I was a bit worried about cooling the big 502 in the CanAm project.
I've now tested it twice with the same positive results.
Start in 90deg/90+humidity idling at 950 rpm for just under 5 minutes and the engine reaches 190F where it goes closed loop an drops the idle to 800rpm. Reving the engine at 1500rpm it climbs Slowly to 220. kick the SPAL 16 inch fan and it drops to 190 and slowly cools to about 180.
