Message	Temps hovered around 94F for a bit but it got up to 96.8 degrees by the time we ran the last test, the second run on rad #2. It will be something I'll test when ambient temps start falling - to see what the sensitivity to changes in ambient temps are on the dissipation rates. In this kind of testing there wont be any 40 minute runs, LOL. We are heating the entire system (coolant, radiator, pump, hoses, reservoir) to a temp of 200F, turning off the propane burner, turning on the electric fan, and logging temperature every 5 seconds. This gives us a heat dissipation rate of the radiator core over a range of temp from 200F down to 100F. Each 5 second interval provides us the temp drop, which is what you see in the plots for comparison purposes.. Enthusiasts soon understand each other. --W. Irving. Are you an enthusiast?
