My friend has a WRX with an air-to-air intercooler right under his hood scoop, and he says when its really raining hard out and the intercooler gets all wet his car runs better and quicker, obviously getting more cooling from the water. He then told me his friend with an STI has some jets of water that shoot onto his intercooler with the push of a button, and I got to thinking if that would be beneficial to a procharger intercooler, since its quite a bit bigger. I think rigging something would be fairly easy to shoot some jets of water onto the intercooler, just get some wiper nozzles (not sure if that’s the correct term, the little things that spray your wiper fluid) and rig them to some kind of pump and just have a switch that turns on and off the pump mounted in the car. It's probably more trouble then its worth and I'm just thinking out loud here, but anyways I'd be interested in what you all have to say. Thanks.
