Getting hot on the highway with the AC on.

Some years ago I got sucked into a "triple pass" radiator and the only thing it was good for was triple the stress when idling. I tried every fan/shroud configuration possible and had a high flow thermostat and flowkooler pump. The temp would just creep up at idle until it was time to pull over or get on the freeway. All I changed was the radiator to a champion 26" 3 core (with no fan shroud) and presto problem solved. I will keep my water flowing the same way I like my cars, fast lol, (says the guy who hasn't been to the track in over a decade :D)
