Anybody making a water to air intercooler for 3.5L EB yet?

So are you referring to a separate liquid cooling system that only serves the intercooler or using engine coolant to lower the charge air temperature?
A related question: Has anyone measured the actual air temperature between the discharge of the turbo compressor section and inlet to the intercooler? How hot is is this air on a day with 72 degree outdoor temperature, for example?
It wouldn't seem like compressing air from zero to 10 psig would raise the temperature drastically in the first place.
**Edit: Clicked on your frozenboost link to answer the first question.**
Someone should figure out a way to use the A/C compressor to make chilled water for the liquid cooled IC. Fill the system with a 30% Dowfrost solution.

So, in short, an *** ton (neglecting inefficiencies and wall cooling).
There is a reason people use intercoolers, and it's not because they want to.
Note: Also, keep in mind that temperature in fahrenheit isn't a really good measure of "relative increase". Kelvin, because it's based on absolute zero, is better.

Your best bet is to fab up the inline barrel type shown on the OP's link to the FrozenBoost site -

You would need one for each turbo, in addition to the external radiator. I understand why you need this in a mid engine car, or a dragster where a cooled reservoir can provide water for one run, but in our trucks the best place would be in the oem CAC location. The only benefit I could see would be the possible reduced turbo lag due to the fact that the water to air inter-cooler has a much smaller volume to pressurize when compared to the CAC.
The added complexity, another cooling system + electric pump, added water hoses, etc. seem to make this more of a project of "because I can" that a practical mod. while I don't want to debate the "water vapor comes from pressure drop, vs water condensing on a cold surface" they are both factors. The moisture will still condense on a water to air inter-cooler, but with a smaller volume with higher velocity airflow through it the moisture should blow through anyway.
Every application of a W/A inter-cooler that I have seen was for a specific reason - superchargers that blow through a small plate on top of the intake, mid engine car where plumbing for air would be excessive, or special cooled reservoirs that can only be used for a very short time before they become heat soaked. Doesn't seem to fit what I use my truck for. Just my 2 cents.
