Actually, Mike, it does lower the charge temp on turbo applications. I say turbo applications because I dont know if the water has enough time to do its thing with the nozzle post-blower on a JRSC. Spraying that close you're really going to be soaking up cylinder temps, not charge temps.

WI is ok...Its pretty expensive, and for what youre getting, I dont think its that amazing of a setup with the JRSC.
Honestly, I cant predict what gains you'll see on a JRSC system, because you are limited to that one nozzle (unless you dont mind getting new screws every year or so.

). A nozzle far enough away from the blower not to do any damage is likely to not provide any gains simply because the air at that point is ambient temp. So unless you have your water in a 12V fridge or something, it isn't going to do anythin but saturate the air with noncombustables.
The aquamist system is rather expensive, but you can piecemeal yourself a kit for much less. ($200 or so) Instead of using their system to map water, I would suggest a boost activated system. On a JRSC, you could have a switch activate the solenoid at say... 5 pounds.
