btw that dude whos selling that has "0" ebay rating hmmm.
Its made to order...
ya the 0 rating does not worry me becuase if you guys want to get a GB i'll get his phone number and his address and all transaction via paypal using credit card.

Spray before the run, especially if you're using liquid like water or alch
Unless you want to get kicked out of the track

Why would you get kicked off the track? A correctly done water sprayer will just spray a mist through a mist nozzle you can buy at home depot. It's not like you are dumping water all over the track or steam will be streaming from your engine. I think doing a combo CO2 and H2O (separate) sprayers would be very smart. C02 is expensive, and you would only have to use it when you really needed it if you had the water for regular use. I am probably going to do some wiring mods so every time I spray my IC my winshield wipers don't swipejersey_emt said:

With a sprayer and upgraded SMIC we should be getting the same cooling temp with less pressure drop and less added weight on the front end.(wow)mazdaspeedchick said:yeah what about special ppl who have FMIC's?

If you are simply spraying water, you will get 10 times better gains if you spray it into the airstream after the turbo instead of just coating the intercooler.
Water/alcohol injection has been around for years and can cool intake temps down tremendously better than water being sprayed on the outside of the intercooler. You have to use a high pressure pump, though- a windshield washer pump wont really do it. an old fuel pump work well though.
Most water injection kits come with boost switches, so they spray when you are above a certain boost and some have full throttle switches too.
No matter how you do it, if you are just using water alone (or water with alcohol or methanol), you will get enourmously bigger gains by spraying it into the airstream.

If you spray water into the airstream before the turbo that would turn to steam before it hits the TB. So, wouldn't you have an air/fuel/water mixture going in right? I know this might be cooler, but wouldn't it be a bit damaging to the engine? Correct me if I'm wrong I'm not really a mechanic or engine expert.
The point of water injection is to have an air/fuel/water mixture going into the engine. As long as the water is sprayed in a fine mist, it cools the air down better than most intercoolers, and has no harmful effects on the engine. The only thing to make sure is that you do it after the maf and after the turbo. This is because over time, the water droplets hitting the turbo blades can actually dent the blades (because turbos spin so damn fast).
Water injection has been around for many years, they used it on planes and race cars. By introducing a fine mist into the intake, the surface area of the cooling water is so great that the air temps are reduced by huge amounts. Check out this link: www.snowperformance.net - these guys have one of the higher quality kits on the market.
I am torn between using water injection and getting a water-air intercooler. The water-air intercooler is nice because it is a closed system, but the water injection is very cheap, and very effective. But, you have to refill the bottle every now and then. Most people get a bottle that is big enough to last them an entire tank of gas, so they refill the water when they refill the gas.
Also, most people inject methanol or alcohol in the mix with water as well. This helps to reduce detonation as well because it basically increases the octane of the air/fuel mix going into the engine.
You dont have to worry about damaging the engine because most of the water evaporates before it hits the cylinders, but even if it hasnt evaporated by then, it is such a fine mist that it doesnt cause damage. Actually, if you read the faq on the link above, you will see that an engine that was torn down after two years of water injection showed no signs of wear.
Holley made a kit for a while, a few companies make kits for the Buick Grand National (but the kit is universal), and there are a few other companies that make kits. You can actually make it yourself if you make sure to use a high pressure pump and a good nozzle tip.
One thing that I don't like about it is that during the winter, you have to use a water/methanol or water/alcohol mix so that it doesnt freeze in your engine bay, and adding either of those ups the cost of refilling it. Actually, methanol isnt too expensive if you live near a place that sells it, but I don't. But, during the winter, its not even that important to use the water injection because our intercoolers work better in the winter anyway.
People get huge gains with this stuff, but alot of people turn up their noses at it and say "it's just a band-aid" and that it doesn't fix the problem of needing a better intercooler. But, if you always have water in the tank, then it does fix the problem, and arguably better.

so say i went and bought a fuel pump, hose and sprayer nozzle, all that would be left to do is tap into the intercooler piping and place the nozzle there? Any idea what size of nozzle to use?(or specifically where i could buy one?) Will the water damage (by rusting) the intercooler at all? I think I am going to be doing this very soon, should compliment the C02 sprayer exceptionally well!

Good info. I still have a question though. Why would you need a high-pressure pump if you only are spraying a fine mist? Also, if you use the whole thing per tank of gas, is the thing spraying constantly when your car is running? I will check out the link you put up to see if that answers my questions, but this sounds like a really good idea. It would be great if it came with an on/off switch if it was running constantly just in case you didn't want to use it all of the time.

I dont think it sprays constantly. You can set it up to spray at wot or with a switch. I checked out that link and i think the kits those guys make can read your maf and apply the spray when it senses boost, but thats a little too expensive for me! lol
I check out the site. Sweet idea. The only problem is that the psi rated for that pump is for a 93 mustang cobra, which has more boost than ours. That wouldn't be a problem because you are able to adjust the injection by the variable controller than attaches to the output signal of the MAF. This is said to help prevent "misfire", which worries me that if you don't get the proper mix at certain flow levels you might hurt your engine. Also, we would need to verify that our MAF are 5V, or that they use similar signals to the mustang. This does look like something that is worth looking into, and if a vendor wanted to do something MSP specific I'm sure it would be a hit. That would allow the testing and experimentation. I might go and modify the mustang kit to work with the MSP, but it would be much better to have a vendor do the testing on another car before I put it on mine.
so i take it i shouldnt be experimnting shooting water into my brand new car then lol. Maybe I will just get a fuel pump to power a sprayer that will spray onto the ic rather than the winshield washer pump ive been planning on using,then when i edumacate myself a bit i will start the injection lol (dance)
