Some of the performance shops sell a complete system but they are easy to make and cheaper
you need a bottle to hold maybe 1-2 ltrs - windscreen washer bottle from wreckers is ideal as they have a pump built in - it has to be mounted under the bonnet somewhere
I have seen one that was mounted under the air con outlet, then instead of running the water on the ground every time you stop it refilled the bottle but depends on your car if this is practical
then wire the pump to a switch on dash
next you need a micro spray (from the irrigation section of any garden ctr.) what you need is a 1 or 2ltr/hour fan spray this will give a fine mist The spray is mounted in the air intake in the bonnet so the jet covers as much of the intercooler as possible
then a length of micro tube also from the garden ctr to connect the jet to the pump
the small ammound of water is no problem as most of it evaporates when it hits the hot intercooler ( you would get as much water in driving in the rain) evaporating the water is where the heat energy is absorbed thus giving lower inlet air temp. to the engine
i have seen one car (super high performance) whice ran an airconditioning system before the intercooler claimed big h.p. gain but it seemed a bit over the top
if you like i would have sprays i could post to you ?I can also email you a sketch if its any help
Hope i've explained the system
