Depends very much on the temperature of air at entry to the cooler,
the respective rates of flow of coolant and air, as well as the
heat-exchanger characteristics. If the manufacturer of the heat
exchanger isn't able to provide you with heat-transfer
characteristics given the flow rates and temperatures, then you'll
have to measure it on a test rig. 

Best bet is to go to the engineering section of a library and look
for heat exchanger text books. The liquid-air intercooler is just a
radiator "in reverse".
