Belt driven air to water intercooler water pump?

[dave96dcm]

I'm going to be making my own intake manifold and bracket setup for my Magnacharger and I'm going to have a air to water intercooler so I was just wondering if there were any water pumps that would be good for this, I was thinking about looking into a marine water pump because that is similar to what I would need, but I do not know what a good gpm would be, I'm assuming that I would not want much, probably 1 gpm or less?

I posted this in the open discussion instead of the engine section because there is alot more traffic here, but if any mods think it should be moved please do so.

Thank you.
