Whipple uses an air to water intercooler under the blower in the manifold, has a -12 inlet & outlet at the back. Look a few pics up to see the Killerchiller unit mounted behind the headlight. Liquid coolant tank, to pump, to Killerchiller, to intercooler, back to tank & repeat. The killer chiller runs in tandem with the small Vintage air unit in the car. It is the real reason i am having AC on the car. its same technology that they use in the new Demon. There is a electronic ball valve that cuts the AC coolant flow to the evaporator under the dash for race mode. But for cruising & drag week the AC will be nice.
