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

It’s an EPW?? I think that’s what it is. Or something like that.

The water pump is only 6% over driven but I’d like to get to 20 over.

On hundred plus degree days it runs right at 160. If I hit a train or some Uber long traffic light it will climb as high as 175 but it cools off once you get moving.

Hence why I want to get the pump and by the mechanical genius of bolts the fan up to 20% over.

I think it would clean that up.

I have some need math I did somewhere but the upshot is I calculated pump speed where I’m at and then how many more rpm I had to get before it started to cool down.

I figured I needed about 200 rpm more at idle and that’s what 20% will get me.

Finding the pulleys is not that easy.

I’ve looked into getting some made but I doubt I could sell more that two or three sets. This thread is proof positive that old wives tales never die.
I think I'm gonna try an experiment. I have a GM water pump pulley that's the same 5/8" center hole as Vixen's water pump, but a different bolt pattern, of course. I'm gonna make a jig out of a Mopar pulley and drill the GM pulley to the same bolt pattern. It's only like 1/16" off for the depth and one water pump spacer will fix that. Here's the skinny though. The slant 6 crankshaft pulley is 7". The stock water pump pulley is like 6 3/8". So I'm over driven a little now. The GM pulley is like 5 3/4". I don't have over heating issues by a country mile, but I'm curious to see if it'll make a difference.
