intercooler spray? any tips etc?
« on: June 03, 2005, 06:51:58 PM »
any cunning plans, i guess the cheap way is to just use a washer jet & point it at intercooler (guess may as well do it from the back of intercooler rather than trying to do it from where the cold air goes in) given as i understand it the gist is it\'s just the water cooling what it touches is there really guna be much point sheddig out more cash for a "proper" misting device? Saw a relatively cheap un on ebay
Going to be getting wi fitted but still wana get a spray as well given temps r soooooo bad on my standard intercooler so fishing for ideas/tips?
Cheers

I have a NX Spay bar that i use for water. I used it a couple of times but tbh you only really get any benefit at high speed and even then ive only found it drops by a couple of deg.
I would save the cash and get a FMIC.

The water droplets from a windscreen washer are too big! You need a fine mist type spray. And also to get a good mist, you will need an higher pressure pump.

Not sure where you can get them from, but there are some kits out there.

Not sure if you\'re joking or not, but putting it behind the intercooler and directing the spray to the vanes will not work. Considering the quantity of air moving through the \'cooler, you\'ll be trying to spray "into the wind", so to speak. Very inefficient, if it works at all.
The cooling effect is because the water evaporates off the surface. That needs energy, i.e. heat. The water therefore removes the heat from the \'cooler surfaces  , allowing more heat to be absorbed......the cycle continues. For this to have any effect at all, you need a large percentage of the surfaces of the \'cooler covered in water.......hence the need for a mister.......the mist covers far more of the surfaces than a heavy spray.
There\'s probably other considerations to........

TBH if you intercooler (interheater) is getting so hot that water will evaporate from it then you are heading down a very slippery slope.

Why can\'t you take a carbon dioxide fire extingusher to the Drag strip and spray it all over the Ic just before you go?

Seen pople do it with Nitrous but that seems a bit of an Expencive way of doing it to me? the only thing is you want somthing that is clean and doen\'t leave powder all over the show?

Basicly any compresed gas will freeze when its sprayed into the atmosphere.

But you may say its for when its moving, but would\'nt this tend to inply you have ither the wrong IC or its blocking the air flow to the rad? to date the best adition to the Ic is water Injection, which is worth every penny in my opinion.

Grizzly my son.
My kit works as either n20 Co2 or H20 depending on the solenoid i use and which tank i use.

Not tried n20 yet tho but you are spot on with the co2. Rich is also spot on. The tracks dont really like you using it.
TBH its more show than go i use it when i really cant get air moving as i would like.

I have seen some people use a electric fan on the ic to force air through it.

Si get a better form of charge cooling.

You don\'t need high temps to evaporte water from a surface. A good analogy is your skin. You feel alot colder if your skin is wet with a flow of air blowing over it, than if it was dry. The water will quickly be lost from the skin, yet skin temp on the surface is 30-32\'C. Apply the same thinking to the intercooler. I guess the key is to coat as much of the surface, but to still not put so much on, as to block the channels for the air to move to also.

The problem is keeping water there, or in the case of a Charge cooler the water absorbing the heat quicker than its getting rid. This is true on the Track in high Hp aplications but a Charge cooler is good on the 1/4.

The track is all about air flow and haveing a clean run out the other side. Its ok having realy good ducting if the outlet is too small or you kill the air speed,by sending through the Ic before the rad not getting good flow through the rad and there for higher temps before it even gets as far as the Ic.

What you are going to have to watch as well is you don\'t start putting large amounts of water on board the car, or even worse in the Ft of the wheels in the case of a Charge cooler?
