- Intercooler Air/Liquid Assy.
Spearco offers basic air/liquid intercooler cores that can be combined in a large variety of ways to suit intercooler needs on Roots or Centrifugal superchargers and turbochargers.
Air/liquid intercoolers operate by pumping cooled water through the cores either from a front-mounted radiator or heat exchanger, or chilled water produced by circulating the liquid through a container filled with ice, as used in drag racing. Depending on engine size and heat load, you will need a container that will hold a minimum of 12 pounds of ice.

If a front radiator is used, this should be as large as possible since the temperature of the liquid entering the intercooler determines the cooling effectiveness. Radiator technology is preferable rather than oil cooler technology, as these are specifically designed to cool water/glycol. When these intercoolers are used with chilled water, it is possible in some cases, to get charge temperatures below ambient temperature. Therefore remarkable increases in air density and power are possible.
