Any opinions on which model/flowrate pump would work best and still remain fairly quiet while running? Also, is it a good idea to use a pressure switch to activate the pump at a predetermined boost level for daily driving? I've already relocated my battery and got $350 tied up in the custom fabricated, spearco-cored AWIC; so I figure it's too late to abandon the project in favor of an air/air unit. Plus, I'd have to do some bumper cutting to make one fit in my Accord . One last question: Will a generic copper tube-and-fin oil cooler from Summit be sufficient as a front mount heat exchanger/water cooler? Thanks in advance to anyone who has experience with a project like this.
