I have been playing in my garage and made this, don't suppose it will make the slightest difference but it stops me drinking beer for a while!

Got thes nozzles made


And fixed them into my bumper


Fitted another pump into the screen wash tank


And fitted a pressure switch to control it


It starts the pump at 7 psi

 

personally cant see why it wont make a difference ( tho am sure to told otherwise) as it should reduce i/c temp and increase density etc

where you get pressure switch from fella?

 

So when it reaches 7psi it sprays diluted screen wash onto your rad or whatever?? I dunno whether i'd like diluted screen wash sprayed on anything in my engine bay

 

of course it will drop the intake temps but by how much no one no's,how efficient is your cooler??
try putting your hand out a car window at 50mph and then doing it with a wet hand !

p.s evos come with water spray.

 

I got the pressure switch from rs components. No screen wash in tank any more, would have liked a seperate tank but could't fit one easily so thought i would try this, if i cant clean my screen with water i will have to re-think.

 

Subaru's also have them, but i think it is quite accurate how you place them and how they spray. Try it with a tempsender in your charge carrier. The only way to find out if it does anything good

 

fair do`s about windscreen wash,i would say a clean water better tho

if jets have a wide spray then surely it would work or more jets?

could be checked on a dyno & set up,future feature for fast ford maybe or maybe not.......Dan?

 

If your intercooler is crap then this is needed if you have a good intercooler then it is not needed i tried this on the pace interwarma 10 years ago and made fuck all different to it

 

Wrong!!!!!!!!!!!Youre talking about "windchill" which has NO affect on a intercooler.Spraying water on intercoolers was tested and the results reported on the Ford RS Owners site yrs ago.Done by a well known respected member,(could have been Steven RW,maybe???) anyhows the result was that it made no difference what so ever!!! Regards,Micky

 

Would be the same as driving in the rain surely.

 

point taken but i cant see why major manufacturers use it then ?????

 

I wouldn't call it windchil. What he has described is the effects of latent heat evapouration. It works.

 

I have a similar set up on my car if your happy then dont worry about the replies, just one thing if you have plumbed the pressure switch into the knock sensor hole did you drill it first as its not got a hole already so switch will not see any pressure?

I did this 10 years ago (OMG have I really been playing with my beantin that long). Used a secondary screenwash pump and added a seperate tank with neat water in it.

Only thing I found with it was once I'd stopped and the excess water was dribbling on to the space people would tell me my car was leaking.

Did it make a difference? I'm not sure either way but it seemed a lot of hassle and more plumbing and wiring for an effect that if at all present was minimal.

 

did your s2 used to come to witham essex back in a day Oranoco??probs got my wires crossed lol

Didn't check that and have not tried it yet could be plan B

The pump has to be lower than the nozzles or it will dribble

 

IMO and from what I have read, anything under about 150psi of pressure creating a extremely fine mist of water is next to pointless!
The key point is that the water must evaporate – it is this change of state from water to a gas which absorbs the energy/heat. If the water droplets do not evaporate, they basically provide almost no cooling performance. And the key to getting water to evaporate is to use very small drops – an atomised mist – which dramatically increases the surface-area-to-volume-ratio of each drop, promoting evaporation.
But as you say it's just for fun and keeps you from drinking beer! lol
One thing I would do differently is use a Charge temp switch not a boost preesure switch, that way you attempt to maintain a constant control over the charge temps rather than only cooling when on boost.

 

your getting water injection mixed up with water spray.

 

Nope!
Some of my Info comes from this site look for yourself.... http://autospeed.com/cms/title_World...0/article.html

Although you would get better results power wise using water/meth injection!

 

u say in your opinion then copy and paste from a website thast using marketin jibber jabber to sell a product quality

 

I said...
which it is!!

That was just one copy and paste from one site I used as an example whats wrong with that?? If you want more info to back it up then look around for yourself....... I did! Which is how I formed my opinion!

 

dont believe everything u read

 

I only done this after seeing the water spray on my friends Subaru STI, I always thought it would have been a super high pressure mist that covered the whole intercooler but it wasn't. I didn't think it would make any difference or everyone would have it by now but it can't be that bad an idea or Subaru wouldn't bother.
