Refrigerated  Air / Water Intercooler      RAWIC

The RAWIC is an experimental project.  It is designed to produce an intercooler system that uses the cars AC compressor to cool water circulating through an air/water intercooler.  Water coming out of the intercooler is first pumped through a heat exchanger mounted to the front of the car.  From there is returns to a cooling tank mounted in the trunk.  It is channeled past a cooling core built into the tank.  This core is part of the AC system and shares it's refrigerant.  The core is downstream of the compressor and actually improves the cars air conditioning while in use.  The tank has special baffles built inside which cause the water to move in and out of the core.  The internal design of the tank accounts for much of the success of the system.

Testing:  Many hours of testing have been done with the system.  The first tests were conducted without a heat exchanger.  The results of several different road tests are shown below.  Testing with the new front mounted heat exchanger have not been done yet.  A broken valve and "crank walk" problems have required a rebuild of the engine.  The rebuilt engine is about ready to install in the car.  Once the engine is broken in, testing will continue.   

Please excuse the charts.  They were imported from different formats and I have yet to learn how to get them all the same.
