If you incapsulate long pipes in some of the stuff these people sell it's like adding another massive radiator. Just remember, removing thermostat for faster circulation through this modification will be counterproductive. Antifreeze will not be able to cooldown sufficiently enough going thorough pipes faster. However, it will be cooled on the way out and cooled even more on the way in. You can also install small rubber baffles in the heatsink gills every several feed or so to capture incoming coder air from down below. Old 911 Porsches have rubber baffles under the car for the air cooled engine shroud.
Keep in mind, that dissipated heat needs to go somewhere. If the car's moving, most of it goes out the back but if it's stopped, that heat will radiate up into the passenger compartment.
