Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???

First rusty I agree with you. Second how does the thermostat stop a motor from running to cold. It opens at a predetermined temperature and then controls how much coolant goes thru the motor to keep that temp. There is no two ways about it. Face it. It all has to work together to get the job done. With all the research done at the manufacturing plants don't you think the engineers used the right formulas to figure these things out. If you run without a thermostat chances are you will not pull enough heat out of the block causing the oil to run too hot and burn up your bearings and cam. If your car runs to cool what happens to your oil it heats up and breaks down.

It stops it from running too cool because it acts as a small restriction. Without that, there would be too much flow and the engine would run too cool.

Here is the main ball of wax with all of this. Unless you have a radiator that is capable or more than capable of shedding the heat generated by your given combination, you will very likely be doing other "incorrect" things to get the engine to run cool. This one reason in itself is why most people have difficulty. They simply do not choose a radiator with enough heat shedding capability.
