what to do w/the intercooler waterspray?

rossscarbro · 04-01-2003, 09:36 PM

Okay, so maybe I'm just new to all this....I've got my '04 Sti on order (hopefully Sept. arrival). Here's my question(s)- I understand the reason for having the waterspray on the intercooler...but when would you actually use this? Could you use this too often? Should you use tap water or distilled (to keep mineral deposits away) Would you use this just before a launch or while your'e speeding away? One more question...the DCCD- again, I understand the reason why it's there, but when would this be used to its fullest potential? When would you send power to the front wheels, or vice-versa? Can you do this on-the-fly? Any experienced answers would be great!

My uneducated guess would be to hit the water spray just before the launch and after I shift into each gear.

Ok, i'm not too sure what the poll is asking. I checked "no" as in I will not be making any modifications to the car. But, I will be driving it competitively in Time Trials, Track Days and Autocross.

The question of "to race or not to race" should be a seperate question from the "to modify or not to modify" question.

StealthWagon · 04-01-2003, 11:43 PM

The DCCD doesn't send more than 50% power to the front wheels in manual mode, (why would you want to?), it just biases as much as you want to the rear, (up to 65%). You'd want to do this to make the car more of a rear wheel drive handler on dry or maybe 50/50 for wet conditions. As none of us US drivers have experienced this I recommend tons of experimenting and practice before I drive this beast balls out!

rossscarbro · 04-02-2003, 10:35 AM

Okay, my bad on the poll, I'm a noobie scoobie, remember? But I think some of you are missing the main points- my questions regarding the DCCD and the waterspray.

somebody else · 04-02-2003, 04:35 PM

I am going to m0d the intercooler water spray so it dispenses Dr. Pepper out of a spigot on the dashboard.

I am going to m0d the DCCD so it fades front to rear the kickin' stereo I b installin'.

I also be m0ddin' the badges so they glow pink at night!!!111!!

Well, the waterspray is going to be most useful when the water has lots of air passing around it to allow it to evaporate and remove heat from the intercooler. The spray would be good at highway speeds when the engine is heatsoaked.

If you let the DCCD in automatic it will be used all the time. I doubt I'll turn mine to manual, unless it's to experiment at an auto-x. Locking the DCCD at 65/35 may give the car a more consistent feel when cornering, but it may mean that if you start to spin the DCCD won't be able to adjusts to save your ass

Thats an interesting idea!

How about tapping off the stock spray feed line with a 'T' and filling the tank with Gatorade.
That way both you and the car could be equally refreshed!

Where would you install the spigot though?

Maybe you could run an extra long plastic line like from a 'Camelback' (tm) with its 'BiteValve' (tm) from under the dash to the drivers seat. You could even rig up more T's and have a source for all four seats!

That would be stupid cool, eh?

There was an episode of Cops a few years ago where they busted some guy for drunk driving. He had re-routed his winshield spray hose to the interior of his car, and filled the wiper fluid resivor with whiskey.

all STis come with IC waterspray. i have hooked up the STi waterspray nozzles and STi switches on my car as well. the USDM model comes with a weak manual only waterspray, so if i was you, i'd upgrade to an automatic spray system. the JDM STi has an auto sprayer that is controlled by the ECU, but i just used a pressure switch and a relay and adjusted the switch to turn on the waterspray at 14.5 psi and up, when the auto spray switch is on.

the problem with the intercooler is that on hot days or when the turbo is pushed hard, it gets heatsoak and isn't as effective. when you are at the track (which you'd better be if you get an STi), you will really be able to use the IC water spray. but it's not going to be as easy to use with it being manual. i guess every lap you could hit the button for a couple seconds or something. that's all it really needs to keep cool, and you really will notice a different. the waterspray works great.

Janq · 04-02-2003, 06:30 PM

LMFAO....More seriously, how about rigging up atomizers at the front brakes off the spray line to cool the brake rotors.

A mini temp sensor could be rigged up to provide an ambient air temp reading to a visual source (gauge or light) in the dash.
When the gauge or light detremines the rotors are getting hot then a small spritz of grape Gatorade (or just plain water) could be misted on to the rotors remotely.

It could look like the misting/dump setup folks use with NOS at the front fenders only on the cheap, and actually useful.

I've got my eye on this setup that I found a few months ago;
AutoSpeed - Intelligent Intercooler Water Sprayer

rossscarbro · 04-02-2003, 09:48 PM

cool...I checked out the site...definately stuff to think about. Thanks. What does anybody know about using it in the winter? Up here winters can be harsh. Any one know what'll happen if I use it in freezing temps? I'm sure I wouldn't need it, if really cold air is coming in the intercooler, but any thoughts?

Janq · 04-02-2003, 10:38 PM

I wouldn't use it in cold near freezing ambient temps though I'd imagine heat from the block would keep under hood air temps well above the freezing point.

It would probably be best to cut the water with something like 10% methanol to drop the freezing point.

Is the button for the manual water spray near where the foglight switch is on the current WRX? If so, it may be more useful located to a push button on the dead pedal, sort of like the old high beam/low beam dimmer switch in Fords.
