Also think we are over complicating this "heat exchanger" - its a simple water radiator nothing else - to make a custom one or find a better one that fits should be dead easy...

I guess everyone is really confused with this "heat exchanger"up front,and another heat exchanger under the S/C.Are you saying that the front heat exchanger is nothing more than a glorified radiator?
If thats the case we needs to see if the primary one under the S/C can be modified if possible,or like you said ,build a custom radiator,that is effecient enough to help dissepetate heat.
HI-TECH BOYS said they have a FMIC thats effective,i would definately like to see their set up and how it works.

JAMUSA - in function Steve is right both "ends" of the system (heat exchanger S/C and radiator) are nothing but glorified radiators - both move heat from(to) air to(from) coolant liquid (antifreeze+water)...one soaks it up (at the S/C) the other radiates it (near the nose of the car). This is the essence of an air-to-water intercooler system. (The other type - common on turbos - is air-to-air and then there's only one "radiator" where boosted pressurized inlet charge is fed via a radiator where air circulates around it to cool that charge - these are typically fed by large-ish air scoops on the center of the hood)
Now the "radiator" at the S/C end has a different form entirely from a normal radiator (one used to cool the engine) as it must fit close to and inside the air circuit (if you make the path of air flow longer it will slow the response and make more "squishy" the response of the S/C to throttle input). This "radiator" must be in a closed pressurized S/C chamber (actually two one per bank of the V).
The other end is really just a smaller regular radiator and can either be replaced or supplemented with another...of course pick a good fit, quality and one that will not burst or leak under this use and your all set.
