Just an idea

[BlackBEAST]

Ok my buddy from high school who has a WRX STI was telling me that STI's have a water tank in the trunk that if you press a button in the cab it squirts water onto the outside of the intercooler and gives it a "boost" when really giving it hell. Im guessing it cools the intercooler down making the air inside the intercooler cooler and denser which is good right? so I was just wondering if anybody has tried this or if anybody thinks it would work? I know it sounds like an external method of a water/meth injection but who knows? I could easily make a rig up cheap to squirt water on the outside of the intercooler if he is crazy or if it is true

I think a little of both. I know people spray nitrous on the intercooler to cool it, but I highly doubt that STI's come with that tank setup from the factory. Maybe I am wrong though. Sorry I can't really help more.

I have heard of water injection which was very effective in the 60's

pretty much a water/meth kit like this:Stealth Automotive. Snow Performance Stage 1, Stage 2, and Stage 3 Diesel Boost Cooler/Water Injection Kit

STi intercooler sprayer - ClubWRX Forum - Subaru Impreza WRX and STi Community and Forums

From what these guys talk about it sounds like it does come with it from the factory, it is atleast confirmed that there is atleast a sprayer that sprays water onto the intercooler

this sites give some stats and more info

Impreza WRX STi intercooler "booster"? - Ultimatecarpage.com forums

"The intercooler is larger than that on the WRX and, during hard acceleration, the driver can spray cool water on to it via a dash-mounted button, giving the car an instant 30 per cent power boost"

hell even if it gave a 5% powerincreace it would be worth it, and an idoit could do it how harmful could spraying cold water on the intercooler be, and would probably be cheaper then a meth/water injection

yea I figured it would be like that kit but doesn't it inject meth/water into the engine?

what about a homemade kit that sprays water onto the intercooler like the wrx sti ^^^^^

this is all a random thought I had and figured I would see what you guys say but I might just be too

pretty much yah... it cools the air before it goes into the engine... with the homeade kit it will shoot it before the IC which will cool it their... the air is so hot anyways that it will evaporate it before or after the IC

Im not talking about spraying it into the intercooler but spraying it on the exterior of the intercooler the water would absorb the heat from the intercooler and just drip off on the street, like the sti does i figured if it works for the sti could maybe work for our trucks

I hate to say it,,,but you are wrong,,the STi's do come from the factory that way. The way the suby's are set up is there is a misting system that bolts to the underside of where the hood scoop(this piece is also called the air diverter) is. All the air that comes threw the hood scoop is pushed right through the IC. There is a rubber gasket that seals right around the IC,so basicly the IC is force fed air through that scoop. Guys have done tests on recording the amount of how much the air temp drops because of spraying, and if I remember correctly, it lowered air temps anywhere from about 20 to 60 degrees( depending on how hot it was outside and how fast you where going). The STi IC is about 20" wide14" tall and 4" thick,thats quite a bit smaller than a SD IC. I think you would probably go through a whole lot of water to spray down a SD IC. I'm not sure on how much of a difference it would make on a diesel motor,but it does make a noticible difference on a gasser.

sweet im not crazy thanks for posting! yea your right it would probably go through alot of water but if you only used it once in a while and hell water is cheap just fill up the tank when ever in the driveway with the garden hose might even put ice in there too I think I might try it after I do my FPR shim im going to start gathering parts and do a pre 0 - 80 mph test and after test to see if any difference
