cheap, effective water/alcohol intercooler misting
 

ok, how bout this-
i know you need a fine mist for effective evaporation of any alky/h2o mixture you wanna spray, and i've found a really common object us turbo guys have that mists really well- the stock 230cc injectors. all u gotta do is either apply constant voltage to them or take the little diaphragm out so they are open all the time, and hook the back up to a line going to the washer tank. you get your pressure from the washer pump, and boom. easy, great misting intercooler sprayer. i've got 4 of em (duh), so i was thinking of making two spray the intercooler, maybe one spray the radiator, and i was considering one in the intake charge (i need to do more research on effective placement and proper amounts though). thoughts?

Re: cheap, effective water/alcohol intercooler misting
 

will constant voltage work with an injector, or does it need to be a pulse?

Re: cheap, effective water/alcohol intercooler misting
 

hmmm so just take some hosing and clamp a injector to the hose and the hose to the pump? then just wire a toggle switch to the pump or just use your wiper switch and disconnect your wipers so they don't go off everytime you want to spray you ic and into your chargepipes? what do you mean by the diaphram in the injector? wouldn't you want a mist in the chargepipe otherwise if you remove the diaphram would it make it just squirt out otherwise?

Re: cheap, effective water/alcohol intercooler misting
 

you need constant voltage if you want it constant open.

this is a great idea until you realize that for some reason fuel injectors were designed work with fuel. This doesn't seem like a problem until you realize that fuel doesn't rust things and water does, so after a while the injector starts to rust and then it breaks and you're fucked. just order the spray nozzle from mcmaster, it's only about $5 or less.

search mcmaster.com for mist nozzle and look at the ones around part number 3178K67, I don't remember which one exactly I got, but it's similar to that one.

Re: cheap, effective water/alcohol intercooler misting
 

I got an adjustable 'boost switch' off of Ebay for like $15. Gonna use it for a water sprayer. Use Alcohol or somethin and the injector will last a while.

Re: cheap, effective water/alcohol intercooler misting
 

true about the rusting. so i'd be better off using a pure alcohol mixture. time to break the shine back out lol. (i wonder where i put that keg and boiler?)

Re: cheap, effective water/alcohol intercooler misting
 

alcohol is HIGHLY corrosive as well ::)

Re: cheap, effective water/alcohol intercooler misting
 

not as highly corrosive as gasoline i wouldnt think :P

Re: cheap, effective water/alcohol intercooler misting
 

Fuel isnt corrosive to metal. If you run water or alcohol through a fuel injector or a fuel pump(except 1 with stainless internals) it will rust.

Re: cheap, effective water/alcohol intercooler misting
 

Good thinking FullofCum (lol jk).

Im gonna try to take apart a regular spray bottle (like for 409, windex) and hook up a pump to it and see what happens.

Re: cheap, effective water/alcohol intercooler misting
 

I would just use the McMaster Carr nozzles and marine bilge pump. Bilge pumps are resistant to just about everything since the water they pump out is usually contaminated with oil, fuel and all the other crap that accumulates in a boat hull.

Re: cheap, effective water/alcohol intercooler misting
 

cold start injectors (lots of toyotas have them) will work off a straight up 12 volt source, since they are 100% duty cycle.

Re: cheap, effective water/alcohol intercooler misting
 

yeah theyll work just fine because everybody knows that toyotas inject water for their cold starts ::)

Re: cheap, effective water/alcohol intercooler misting
 

I was just adressing the 12v/injector question. Not injecting water through them.

Re: cheap, effective water/alcohol intercooler misting
 

i am looking at the mist spray nozzles at mcmaster.com....it seems that one would probably want the standard nozzles v.s. the no drip nozzles, but if you were using your winshield wiper pump....which one would you get proably the 40psi - but would you get the 80degree, or 160degree spray???

also how many GPH do you want to be running if you are only running from 10-15psi of boost?

i talk to a guy...and he said that at 60psi the nozzles are good for the following rates....

0 to 200 hp =2.3
200 to 350 = 3.9
350 to 500 = 4.9
10 GPH is for 800 + HP.

i was probably going to pick up the 3.9GPH nozzle for a 40psi setup.

also one more question.....what would be more water resistant - the brass or copper-nickle, probably the copper nickle.

thanks

Re: cheap, effective water/alcohol intercooler misting
 

anyone?

Re: cheap, effective water/alcohol intercooler misting
 

You can get stainless fuel injectors, those are designed to work with alcohol. Summit carries some 160lb stainless injectors IIRC, great for running methanol :)
Also, cars running E85 (85% gasoline + ethanol) will have stainless pumps and injectors.

Re: cheap, effective water/alcohol intercooler misting
 

why not just go steal some wiper squiters from the junkyard and mount them as such?

mike

Re: cheap, effective water/alcohol intercooler misting
 

And your doing all of this to mist your IC and make it run cooler which means cooler air thus in turn more air per cubic inch and more HP? Do I got it? I know. Such a newb.

Re: cheap, effective water/alcohol intercooler misting
 

just strap kain to your front bumper with a little squirt bottle.

honestly tho, you ought to just get a junkyard windshield washer system, pump, bottle, hoses, nozzle, all of it, and power it with a switch by hand, or a pressure switch of some sort so it kicks on in boost.

just be careful with these types of ideas.

if you're in a drag strip and you're dripping water in the staging lanes or getting their track wet, they're gonna rape your girlfriend and kick you outta the track. :P

Re: cheap, effective water/alcohol intercooler misting
 

hmm u could hook this up with the fuel injectors, having them open under boost using a voltage-activated circuit tapping off the map sensor or something. or just use a windshield washer nozzle and hook the washer switch up to the same kind of circuit. i wonder how long the fuel injectors would last b4 they rust? what if u run a water/antifreeze mix or something in there to help with corrosion?

Re: cheap, effective water/alcohol intercooler misting
 

well i think your antifreeze idea would be maybe a good idea....but i dont think that you can combust antifreeze ???

Re: cheap, effective water/alcohol intercooler misting
 

i want to use it for an intercooler fogger, hell no i wouldn't inject antifreeze in my combustion chamber. (actually its happened b4 when the intake manifold gasket for the y8 manifold wasnt sealing and it was leaking into #4, it makes lotsa nice white steam :-X)

Re: cheap, effective water/alcohol intercooler misting
 

and thats not good.... O0

Re: cheap, effective water/alcohol intercooler misting
 

Pow, look down a few threads, there's already a post on this very topic.

Re: cheap, effective water/alcohol intercooler misting
 

except "POW" we are talking about the cheapest way to do it....v.s. the one below us is just getting questions answered about it... POW! ::)

Re: cheap, effective water/alcohol intercooler misting
 

Follow the links, learn some ----. Ford F150 fuel pump = stainless steel internals, get one at a junkyard. Buy a suitable nozzle, and an adjustable Hobbs pressure switch from NAPA, and "pow!" You've got a water injection system that works, and it will be reliable too.

This isn't the cheapest way to do it, but I don't believe that the cheapest ways everyone is discussing will work effectively enough or be reliable enough. If you're going to tune with water injection, I wouldn't want to blow an engine simply because I was too cheap to source the proper pump and burned out a windshield washer pump.

Re: cheap, effective water/alcohol intercooler misting
 

I beleive anti freeze would reduce the performance benefits of the sprayer by a huge lot, because it doesn't evaporate worth damn.

Re: cheap, effective water/alcohol intercooler misting
 

what about water wetter? what kind of characteristics does it have?

Re: cheap, effective water/alcohol intercooler misting
 

I'm not sure, I just know that in your cooling system the ideal coolant would be something that never evaporates because air bubbles in the system are not what you want.

Re: cheap, effective water/alcohol intercooler misting
 

i kind of agree - im just guessing but you would want something that never changes state when sprayed - like co2 ::)

Re: cheap, effective water/alcohol intercooler misting
 

Never changes state? CO2 evaporates when you drop the pressure on it, and if it drops pressure fast enough it forms dry ice. It's ideal for spraying on an intercooler because you won't have any wasted liquid CO2 that leaks down and evaporates somewhere else than in the intercooler.

Re: cheap, effective water/alcohol intercooler misting
 

windshield washer fluid, spray that.

Re: cheap, effective water/alcohol intercooler misting
 

i may be wrong.. but look at washer fluid.. the winter kind.. if in not mistaken its 50/50 water and alchohol.. ethonol.. methanol or something i think... i know a guy here who runs its in his supercharged viper on his alchohol injection setup

Re: cheap, effective water/alcohol intercooler misting
 

the injector idea will not work. been there and tried that. Unless you built about 30 psi pressure the injector will not mist worth a shiet.

I tired that and it failed miserablly. So im still working on a way to use a line off the manifold under boost to push water through only when in boost.

Re: cheap, effective water/alcohol intercooler misting
 

That should work, I saw a link somewhere for it. Pressurized box full of water, with a line from the intake manifold to pressurize it, right? I'm wondering if 10-20psi is going to spray enough water to be worthwhile. If so, this will definately be the best way to run.
