Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???
I had a 22” 3 core rad with a shrouded 2400 Derale 2 speed fan on the 383.
Ran a bit hot at 210 spiking to 217 at times with no radiator support to hood seal.
I went from a 1:1 (6” to 6”) pulley to a 6” crank pulley and 5” water pump pulley but changed to a flow cooler water pump.
Temps dropped to 195-197.
Was it the pump or the pulley I will never know because I didn’t change one component at a time.
In search of even more (cooling) I am changing to a 26” aluminum 2 core with 1” tubes and a twin 12” 3400 cfm spal fans (shrouded).
Science would say that even though I changed both components in the previous setup, they both reflected an increased flow being over driving a superior (opinion) pump.
A 10* reduction in temp is fairly hard to argue with.
The newest change of volume (going to a 26”) will hopefully render another 10*.
I know the experiment was not entirely scientific BUT…. It would seem like the culprit of the lower temp would actually be an increase of flow.
Thermostat (180*) remained the same.
