Water pump pulley ratio high RPM offroad

if everyone else runs a certain setup without a problem, what's different about your setup?

Mopar vs chevy / LS.

Big tires
Driving style lol. I'm pedal to the floor

I'll swap out the radiators. And if issues still show, I'll look at pump pulley. I'd like to change the pulleys regardless due to the fact I don't need a 4 belt crank as I only use two belts. So maybe i'll get the 1:1 ratio kit as well. Its just money...rite? lol
