Intercooler pump So I am looking at getting a stewart pump from Lingenfelter however someone told me they flow too fast and the coolant doesn't have enough time to dissipate heat through the heat exchangers.....thoughts?
Basis of it is, flow is too slow the system gets too hot, if the flow is too fast the systems heat wont have enough time in contact and wont take up the heat and that you need to find the middle and thats what will work the most efficient.
Has anyone done a before/after on temps after changing pumps only and not pump+heat exchanger etc?
Engine is an LSA 6.2L supercharged

"Myths
For those that cling tenaciously to myths, I am going to take one last crack at forever dispelling the Granddaddy of them all when it comes to cooling systems.
The myth is stated as either:
Coolant can be pumped too fast through the engine for it to absorb enough heat, or
Coolant can be pumped too fast through the radiator for it to cool properly, or
Cooling can be improved by slowing the flow of coolant through the radiator so it cools more completely.
NONE of these is true. The simple truth is that higher coolant flow will ALWAYS result in higher heat transfer and improved cooling system performance."
Taken from this article. I assume it would apply here.

Stewart-EMP pump One thing you do have to make sure of with the Stewart-EMP pump is that you have a 1" inlet hose feeding the pump. The pump does very well pumping against high pressures/restrictions but you must minimize the inlet restriction/inlet negative pressure, especially when using the full flow capability of the pump (programmed for 25 amp and 4600 rpm max pump speed).
