thats why airspirit's statement in the dual rad parallel thread kinda sucks. all things are NOT equal between serial and parallel mounting of rads.

in my situ, mounting the rads parallel resulted in such a pressure drop that the air wasn't primed anymore, and mounting them serial the air was primed just ok. so myv65 you got my vote here, haven't forgotten the row between u and airspirit.

not to dis airspirit, his argument was valid, results would be better with parallel in very specific situations, and u will have some work to create that ideal situation: e.g.:

pump outlet, big diameter tubing + pump that can handle the 2 x load. goto a Y where u halve the diameter to each tube to +/- keep the pressure the same. let them come back together after the rads, and increase the tubing diameter again. there will prolly always be a flow difference between the two rads.

so if u want an easy no brainer , go serial dual rads. if u want some headaches and some try and error, go for parallel, doing it right should give u an added temp benifit. doing it quick and dirty will result to nothing.

so; lets get practical. lets say u need 1/2" discharge from pump to goto WB, then u split em into two 1/4" tubes going to each rad. u will have to make adapters to get em over the jumbo 3/4 barbs of your HC's... if u get serial u need only 1/2" tubing, no Y'z, and no adapters, so u choose.
