When the t-stat is closed and water is stopped in the engine it is also stopped in the radiator allowing the air moving through the radiator to cool the water back down. If you run a cooler t-stat the water wont stay in the radiator long enough to cool back down. just my .02
good luck with it

ummm...not really...this is copied from Stewart Warner FAQ
"A common misconception is that if coolant flows too quickly through the system, that it will not have time to cool properly. However the cooling system is a closed loop, so if you are keeping the coolant in the radiator longer to allow it to cool, you are also allowing it to stay in the engine longer, which increases coolant temperatures. Coolant in the engine will actually boil away from critical heat areas within the cooling system if not forced through the cooling system at a sufficiently high velocity. This situation is a common cause of so-called "hot spots", which can lead to failures."
Basically
moving coolant is better than
idle coolant....and a higher velocity is better than slow moving...thats why we have
high flow water pumps if slow or idle were better we should all use stock flow pumps ...even race cars
