The haltech can control either, I imagine the water would work better but that would be harder to rig up, and the fan.. I don't know. Anybody tried either of these setups?

 

That Haltech should also control water injection. That would be MUCH more effective than spraying water on the intercooler or blowing air across it.

Do a search for water injection. Also, throw in Aquamist. They have a system just for you. Just the bare minimum. Because your haltech does the hard part. Controling the water injection. In your searching you will find all sorts of stuff.

However, water injection works. It is how the WWII bombers and fighters got such high horse power. And why the B-52 used to billow black smoke on take off. Water injection.

Yeah I have a water injection setup on my n/a via the window washer thing, was testing out before putting it on the turbo. I know it is more effective but the ********* on this forum thought it was a stupid idea when I posted on it a while back so I came across some more ideas.

 

Huh, you are using your window washer pump for it?

James

 

Hey cool man, I am thinking of doing a WI setup on my NA once I rebuild and street port it. How do you control the amount of water injected? This is the only part I can't figure out how to make.

Thanks

 

I drilled a hole in the plastic elbow before the throttle body and put it a small (VERY SMALL) brass nozzle that I have calculated the flow of (about 15% of fuel injected at full throttle at 7000 rpm) and then connected it to the window washer setup. The only problem is that upon activation of the window washer pump the damn wipers turn on, I will have to go through and clean up that wiring.

If there is interest I can make a kit for converting the window washer pump on either s4 or s5 n/a and turbo.

 

Ok, I have never worked with WI or seen one in person. But, from what I have read the atomization of the water is very important. Does the washer pump put out enough pressure to turn that water into a fine mist?

How many psi or gpm is it capable of?

James

 

For a forced induction application it would easily have to double the amount of atmospheric pressure. But most moddern systems run like 80 psi, to accomodate proper flow and the required atomization. I've heard that WI added 18% HP gain on an FD. I think it's awesome and modern FI technology allows you to do so much with it. now people are using it with N2O, and not requiring the high octane gas (race type) that was once associated with high boost levels.

 

Would rigging the w/s washer sprayer to spray on the intercooler during runs give any noticeable gains at all?

 

I am sure it would. It would give evaportive cooling. Compared to no evaportive cooling i am sure it would do something.

James

 

Spraying on the intercooler would increase the effectiveness of the intercooler, there might be small gains, but safety when running 14psi is what I care about. When the air temp sensor starts giving me a fault reading I start looking for ways to decrease temps.

I have tested the nozzle connected to the window washer and I get a very fine mist, as best you could hope for a polar molecule.

 

there was a post while back that had pros and cons for water spray setups. i think it basically said that the spray setup would cost alot of money to be an effective cooling agent..per dollars spent/gains...but was based on everyday driving and throttle response setup. it basically stated that the spray would run out of water by the time any regular driver would ever use it to its full effectiveness...but was based on a turbo setup on a different car..i think the downside was the water capacity compared to the management during a daily drivers trip..and basically stated that while driving the water was alll wasted during simpl;e acceleration before the car was even given time to warm up and get down to racing.

basically sounded like a management issue that was not able to be controlled

 

****, you have it on a relay or just a plain old switch, you don't turn it on until your sitting on the line with your boost cranked up. You don't drive around with it on.

 

Exactly what I was thinking. Just hook up the w/s washer to a toggle switch and turn it on just when racing. Hell I think I'd use some damn ice water in there

 

A cheaper alternative to dry ice on the ic [

 

what about rigging up tha air conditioning system in some way? prolly use the compressor to cool the water and spray into the water injektion or some shyt like that.
or what about steam injection? via the turbo manifold ir exhaust manifold to steam the water! read this yo

Good ideas but the w/s washer fluid idea is sooo easy, ya know? If anyone really thinks it will help I'll do it. Hell I'll just add an extra w/s fluid pump and bottle and see how it works.

 

so u have a ghetto water injektion update?

 

Seeing how my fd is a sunday driver, I am thinking of just redirecting the existing windshield sprayer to an atomizer on the IC duct. That way I can manually turn it on/off by pulling on the windshield stick....

 

After I got my fmi interest kinda waned, still looking for a brass nozzle.

It is the cheapest w.i. evah!

 

how do u turn off the wiper going right and front when u press the button for water spray?

 

ohhh man........

OK, ever wonder why the injection kits out there are a bit pricey?
They are a high pressure pump, with a special nozzle (not just a regular NOS nozzle or anything).
In order to properly atomize the water, you need the tiny orifice and high pressure pump, otherwise you are just squirting water in. That can probably reduce detonation a bit, but only because it's killing combustion and not just cooling the chamber.

Why the heck would you run it on an NA unless you're running higher compression aftermarket rotors, and have the timing advanced by more 10 degrees? It's just not really worth it.

On a turbo it's great, especially if you are running at the limits of pre-ignition territory, high boost, high compression.

On a side note, an external IC h2o spray is also effective if you want a little bit of help for next to no $$. I've got my IC mounted directly in front of the rad, with an e-fan on the rad that I can turn on when staging... doing a water spray on the IC is super cheap (all you need are one or two washer nozzles in front of the IC, a switch, and a junkyard washer pump) and can really defend against heat soak untill the car is moving fast enough.

 

i can get those pumps. my unc works like HVAC and has all kinds of those ****.
