Liquid Intercooler Pump?

How many GPH is required? Will a bilge pump used in marine applications work also, they have 100+ GPH? I have two intercoolers I'm looking to cool.

Thanks for your responses!
 
if it is for drag racing you need to pass all what you have
in the intercooler in 1/4, on the street i think you will need to
run test with thermometer.
