I am going to attempt to due a write-up on a Do It Yourself mist kit using the stock windshield washer container. Since I removed my washer bottle to make room for my "cooler air" ducting, I've decided to do something creative with it.

step one will be fininding a new spot to mount the conainer, preferably out of sight, mostly likely near the coolant overflow tank.

i will lengthen the wiring harness to accomidate for the relocation.

Finding a tip (or two) that will spray a "mist" instead of a stream will be vital. Im going to expiriment with the adjustable waterbottle nozzels. my main goal is to make it functional with only things around the house, moslty because I'm not cheap, but broke .

pics and further ideas will follow soon, but i cannot start until next week.

if anyone has any ideas or critisism, feel free to chime in.

 

Ive been toying with doing this mysself except i using an old water/alc injection kit, Id like to see what you end up doing here.

 

hopfully it will end up working.

after finding a place to mount the container im going to use a "Y" connecter to route a vaccuum line to either side of the ic core, or possibley on the top aiming down or even from the bottom aiming up. ill have to figure out what the spray pattern is going to be like before i decide on where to mount.

 

Im mounting the tank in the spare tire well and mounting 2 nozzles in the top/front of the ic where the writing is. Im using a check valve mounting about 6 inches after the pump to hold water in the line so ther isnt much delay in spray time.

 

You can get "fan" nozzles in 1/4" sizes at various flow rates and various angles. A low flow 90 degree one would be perfect. The low flow would help cause it to mist rather than spray. Check your local garden center or better yet, an irrigation supply place. It won't be expensive at all. They should also have various fittings, such as tee fittings and valves.

 

i thought about going from back up the car too, just because of all the available space. i was even thinking about using the rear widow washer bottle since i NEVER use it. i didnt think of a check valve though. but from my understanding of fluid physics i dont think it would be entirely needed. the washer bottle is at a higher level than the nozzels are, so the pressure would keep the lines full, or near full. i was just concerned about the amount of piping needed to run it all the way to the front of the car. thats where i lost interest. keeping the lines short (under 2 foot) seems most optimal to me.

and ill definately check out a few garden centers and the nearby tractor supply co. they should have most of what im looking for. im wanting to stick to a 20 dollar budget on this one too.

 

on top mount intercooler?

i guess mist spray would be ok.. long as you dont get non spilling on the hot parts like manifolds etc

 

People wash engine compartments all the time, it's not big deal if water drips onto things.

One thing to consider if the nozzle is lower than the top of the fluid level is that the tank could drain out through that nozzle even when you're not spraying. The pump may or may not stop the flow, I don't know.

The nozzles, some fittings and a bunch of hose should be well within that budget.

 

well yah ive washed engines bays.. you just dont do it when the engine is hot, or the sudden change in temp coolness could damage/crack manifolds and what not..

I dont think this would be a problem tho since a fine mist shouldnt do much except steam if it where to contact cast metal or something.

 

when i saw this thread i thought u were going to do the nitrous intercooler thing

 

I know this might sound like a dumb question but what is the advantage/point to doing this? Keeping temp down?

 

Yeah, intake temperature is very important with forced induction. For one, you get better compression and higher thermal efficiency with cooler air, but also on the other end is that too much heat can induce detonation. The great things about water is it's cheap, easy to manage (in reservoirs, pipes, and such; it isn't hazardous or flammable like gasoline for instance), and water will take on a ton of thermal energy before evaporating, making it great to cool stuff off, especially when it can just evaporate as opposed to a closed cooling system like your car's coolant system.

 

I looked into this with my FD. Alot of people thought it wasn't even worth the effort and that no real gains would be seen... How many of those people knew first hand I don't know.

I'd be interested to see if it improves your IAT's. Do you have some way of monitoring them?

 

Why not use the front windshield wiper system?.. Just make sure you keep your windshield clean. One clean nozzle should give you a decent spray pattern i think. i think it should help some I think Evos have them equipped from factory. Its worth a try i think

 

to clear things up:

1. this is for a FRONT MOUNT intercooler
2. i am using the FRONT WNDSHIELD WIPER SYSTEM to pump the water
3. for a DD/ city car, benefits will be mostly unnoticeable. but as of next year i will be traveling to and from Ohio every weekend to visit my home fom college.

Im running an LTX-8 and monitor everything on a laptop. Im not sure about being able to transfer graphs though. ill be able to take screen shots and save those, but not whole graphs.

 

Im doing mine on the stock top mount. I would onyl be using it for standing starts and situations when I wont be going forward for too long such as a autox or hpde.

 

so i got ambitious today and decided to start it before i leave for the weekend.

First i removed the front bumper



notice the dent in my intercooler.... damn truck hitches....



after searching around for a good place to locate the container, i hit a stump. and ended up putting it back in the stock location.
i ran the hose from the pump straight towards the front end and inserted a "Y" connector to feed to right side.



the hose follows along the back side of the IC core and wraps around to the front.



on monday i will get some spray fittings to put at the tips.
to attach the ends to the core im going to rig some clips to attach to one of the horizontal bars of the IC. updates will come monday.

 

It'll work best when there's airflow over it. The airflow causes the water to evaporate, and when that happens it takes a lot of the heat away with it. This works much better than just cooling it by the water bing cool and cooling it through the water conducting away the heat as it flows over top as would happen as you're standing still. This is why it's best to get as fine a droplet size as you can, ie mist, rather than spray.

 

why don't you guys just do water injection? Not to hate on your already started project but the benifits I think would be alot more. People have used water injection within the last 30 years with great success. Just a thought. Your project looks good so far though.
