Would it make sense to put an orifice, with a tap on each side for the
intercooler, between the radiator outlet and the water pump? The orifice
would produce a pressure drop to move a portion of the water through the
intercooler without the use of an external pump. If your radiator return
hose was, for instance, 2" i.d. a 1.875" orifice might be a good starting
point . HTH.
