Works great in a street or race car. Keep in mind that I live in Vegas, so the interior A/C isn't as good as it would be w/o it. Usually it doesn't take long at all (less than 5 minutes) before I notice an increase in low-end torque, etc. To shorten the story, I had one time that I was driving in 3rd gear and punched it. At ~16 PSI, the wheels broke loose and started putting me sideways.
At some point, I'd like to put freon solenoids inline, so as I can only cool the interior or only cool the intracooler.
Essentially, it's a stock intercooler that (I assume) has the fins removed. Instead it contains an evaporator core, and then the whole thing is encased in water-tight aluminum. At the top are 2 water nipples (1 in, 1 out, direction shouldn't matter). Then there's 2 freon lines (direction does matter). All that it is stuffed between the 2 intercooler necks (one of them being the Dutweiller neck).
