I did some more checking: this pump boasts a flow rate of 30-37 gpm, and says it is "up to 21% more" higher flow rate than competitors. I didn't trust my memory on OEM flow rates, but it would seem that 25 gpm would be great for a flow rate for most street v-8s, so 20 ought to be good for a smaller engine.
Since an OEM setup can handle that with the thermostat closed, just see what speed you need to turn the pump to make the needed flow. Using controllers/relays for multiple speeds may very well just be unneeded complications, considering the amp rates that are being discussed. (Guud, your situation is a little different, there...
) A 10 amp constant pull on a battery, even with an unbelted alternator, won't drag down a battery too quickly. Just thinking out loud of personal possibilities on my car, with a couple of deep-cycle batteries, I would think I could make it the 57 miles to the University and back with no problem.
This Summit pump boasts a 7 amp rate. Does anybody know how many amps a wiper motor pulls? Never having done a load test on one, just from the size of the wires I bet they pull more than 7...
