Coolant can get pretty warm (~160 => 200 degrees F) so to use that Laminova, wouldn't that warm ambient air when not in boost?
Also, you need a good amount of surface area for heat transfer. I don't think four tubes are going to do it. Also, aluminum has twice the heat transfer coefficent of say brass.
Ideally, an intercooler can cool the intake charge down to ambient air temperature, but with a Laminova, you can only cool it down to engine coolant temperature.
I don't think it would be efficent enough, perhaps even deficient. Maybe I'm wrong, it wouldn't be the first time
[Edit: Okay, now that I read those links, it may be do-able. But you're still going to mount an aftercooler somewhere, and not use engine coolant, right?]
