Intercooler Sprayer

It seems inconceivable to me that the intercooler sprayer on my $30K+ '05 STI does not have an auto function, like the standard EVO (MR excluded). Even the stage 2 upgrade (w/toys) on my SRT-4 has an auto sprayer. It should be built into the engine controller logic based on rpm, engine load, throttle position, etc. Is there an INEXPENSIVE solution?

There are several. Best solution would be to get a Hobbs pressure switch. I think they are around $80 or so. It hooks into your vaccuum hose, and is set to trigger a solenoid at a certain amount of boost. Wire it into your I/C sprayer circuit, and your sprayer will come on at the pre-set boost level.

When is a good time to spray? when you driving hard, or driving hard in hot weather?

Manual spray you mean? When you have been sitting at a dead stop for a period of time in hot weather.

Yeah it's good in summer when you are stuck in traffic and only use 1st and 2nd gears. But i don't mind pushing the button couple of times every 5 sec.

It's also good for cooling down while you are at the track. Just press the button a few times right before you stage and let her go

intercooler sprayers kinda aren't allowed at my track... you drip, you don't race again that night... regardless of what fluid you are dripping.

So basically my completely stock car wouldn't be allowed to race? Sounds like a lame track to me. Altho if my intercooler sprayer dripped water from the hood scoop to the ground I would be amazed. It would have to go through my intercooler, and then all the hot piping etc without being turned into water vapor...

Most tracks don't mind water, since they use water for the burnout box anyways. At least, all the tracks I've been to are like that....

I suppose you could drip at pre-staging and they might not notice, I am just saying people get kicked out for using a/c because it drips water, so a sprayer might get you kicked out too

I have a question guys, I am in San Antonio TX and it is said it gets hot here . Where would I get a sprayer? Subaru dealer ? 300.00 ? Or is there a better way ?? I like the idea of ICE on the intercooler.... works very well. Just don't want to keep adding.
