My Cooling Improvement Project (hopefully)

I'll consider that explanation more if anyone can reference an engineering text or technical paper that states it, and I don't mean rodder sites. Until then, I'll continue to understand that higher fluid velocity increases the convective heat transfer rate. Most hot rodders have only a vague understanding of the difference between temperature and heat flow, similar to how people unschooled in electronics can't distinguish current flow and voltage drop.

Not an engineer or anything close. I think it has more to do with "flow channels" through the radiator, and engine, when the coolent flow is too fast. Therefore effectivly, losing surface area. I do know in the "old" days we used to put a large "washers" in the upper hose outlet on the engine, and adjust the size of the hole to get the water flow for best cooling. In general The higher rpm the motor ran the smaller the hole needed to be. This was on circle track cars.

Another thought: Possible water pump cavation? Another thing we used to do was remove some blades from the water pump, and or drill holes in the blades.
