Weight penally?  This setup would require a compressor, a condenser (an
evaporator also but it is already present as the secondary cooler in the
system you described), an electric motor to run the compressor and some
parasitic power from the engine in the form of electricity from the
alternator to run the electric motor.  Of course additional weight for
brackets, etc., would also be needed.  That strikes me as potentially a
rather large amount of extra weight to carry around just to provide some
extra cooling for the incoming air charge.
