DIY: intercooler alcohol/water spray.
I have been home all day very bored..i still have my first car which is a 97 saturn.. well I was cleaning it out gettin ready to sell it and I got an idea.. I decided to take the windshield spray assembly out and attempt to make an intercooler spray kit like sti's have.
WHAT YOU'LL NEED
an old windshield spray (lines, washer fluid container, the little actuator thing attached to it and a nozzle on the tip of the lines.), a knife, a rocker switch,about 45 minutes.
I popped the ep's hood and was looking for the proper place to put the fluid container.. I decided to put it where the stock air box used to be.next you find a place to put the rocker switch. the little actuator thing on the fluid container has a red and black wire.. run those wires to the rocker through the firewall and wire them to the proper places.. get another wire and run it from the positive battery terminal to the rocker also. take the tube that the washer fluid normally runs through and zip tie it to the prongs that are located in the middle of the bumper so that it is horizontal in front of the intercooler. cut VERY small slits in the tube so that the water/alcohol is under pressure when leaving the tube. this will make the liquid a mist rather than a stream. be sure the spray is applied evenly across the fmic using water. then use either water or alcohol to spray.
RESULTS
after hooking mine up I decided to use alcohol. I drove for about ten minutes to get the car to normal operating temp..I flipped the rocker ...although I didn't feel any difference I datalogged the whole drive on kpro after I began spraying, my IAT dropped 3 degrees in 30 seconds.. after 1 minute of constant spray it had dropped 8 degrees! I'm not saying this will help your e/t or anything but I thought it was cool to see something so simple actually work.
