That’s a myth.
It can sort-of be true in some scenarios with some setups where the higher flow and/or pressure causes turbulence or pushes coolant through a bypass or radiator overflow.
Lower pressure also lowers the RPM the pump cavitates, which also happens when RPM is too fast (if a mechanical pump is over-driven for example.).
But just circulating coolant faster doesn’t reduce cooling on its own, since there’s more “passes” so to speak.
@Parso, I lowered my fan temps using the Flashpaq too... I think it worked, but haven’t paid much attention to be honest. I wouldn’t hear the fan anyway over the baby screaming or our 3yo watch the iPad.
Received the EWP150 pump and controller from Davies Craig the other day, pump looks like a serious bit of kit! Still waiting for the fans (decided to use two 11” pushers in front of the condenser, below the trans cooler.) and thermoplastic clamps then I’ll rig it all up and do some experiments.
I’m interested to see if just running the fans alone without circulating will make any difference to the peak temps during heat-soak... that’d be a cheap and easy measure for other Hemi owners.
That seems to be good enough for our Volvo V8, which is a very compact and lean (aka hot.) engine.
