Basically what I'm looking for is a pump that can ACTUALLY pump something like 250GPH after it's been installed in a system with something like a 14 pass radiator....instead of falling to something like 60GPH like that one review showed.
I realize that this high of a flow rate may NOT be optimal but, I would like to have the ability so that I can restrict the flow downwards in order to FIND the optimal flow point.
All the while, I need something that is no more than 30db in noise level and also does not generate too much external heat and does not add more than 1-2C to the water temperature.
Now....that's not asking for much, is it?
