The nozzle is placed in the inlet pipe of the intercooler - it sprays on the inside.
For years I had experimented with external "intercooler sprayers" with very little benefit. Here in the Florida heat my intercooler would become heat soaked very quickly even with an external sprayer. Even with the water injection I expect to dial back my settings when we get up to mid 90's through the summer. But it won't be as much of a reduction as in the past.
I can also say for a certainty now that my car cools down faster after a run. I used to have to idle for quite a while. Now, because the exhaust temperatures are lower to begin with, my cooldown period is noticeably faster.

the reason you run the "smurf piss" is due to the fact it won't freeze in the winter time.
49% water
49% methonal {small detonation properties}
1% blue dye
I know I personally don't have anymore room for another tank in my trunk with my system. I have a 15lb bottle for my 75 tb shot and a 10lb bottle for my n-ter cooler. I ended up getting the aquamist 2s system for $660 shipped.
Here's what I use for a water tank, it's a Jaz 3 gal. fuel cell which gives me all the capacity I need for going full throttle for 20 minutes at a time on a road course.
I put together my DIY WI system using aquamist nozzles, switches and a Shurflo 100psi pump. Works great
WI and meth injection is very strong in the turbo buick crowd. MAKE SURE to read through this forum to find out about what to inject, how to inject it and so on
Aweome, thanks guys...I have been tossing back the water injection idea for sometime now and I think I will use it since it would be able to run more boost on pump gas. You'll probably be getting a lot of PMs from me in the near future
This is kinda a newbie question but i havent read much on water injection. Does it give you HP? Also how much water does it use up? Is the set up hard?

I got this from the net
"Water injection systems are only needed in turbo charged engines. The system has been around for a long time since it was already used in some World War II aircraft engines. A water injection system works similarly to a fuel injection system only it injects water instead of fuel. In high pressure turbocharged engines the air/fuel mixture that enters the cylinders can explode prematurely (before the spark plug ignites, effect also known as engine knock) due to the extreme engine environment conditions. This situation results in severe engine damage in the long run (piston piercing). To avoid damaging the engine, water is injected in the combustion chambers in order to provide a water/air/fuel mixture which not only burns more efficiently and avoids spontaneous detonation but also provides additional cylinder and piston cooling. There are mainly three variations of water injection devices. They are dependent on the location of the water injector(s). The first technique consists of injecting water at the entrance of the intake manifold. The second injects water at the exit pipe of the intercooler. The third technique injects water at the entry of the intercooler and is only used in competition vehicles. In this latter variation most of the in-cylinder detonation prevention is done by injecting additional fuel which is used as coolant (i.e. not burned)."
A really close friend of mine has an 11 sec AWD talon that has a 20g on it with methonal. He is running pump gas[91 CA gas] with with methonal injection and boosting 21 PSI daily driven. Its a really nice setup. Has anyone here tried using methanol instead of water/alky mix? He gets it buy small barrell for like 30 bucks a barrell and it goes months on end on one barrell. Ill talk to him and see if he can get pictures and info for you guys.
P.S. methanol has an octane rating as well not sure of what it is plus it has very good cooling agents.
Heres a sideways picture of my friends snow performance kit...instead of alky he runs straight methanol and it cools and adds octane. As you can see he placed the bottle and pump where the side mount intercooler used to be, you have complete access to the top of the bottle to re-fill it from the engine bay. Very nice if you ask me
I learned about running straight methanol from the buick crowd. That really got me motivated to build the system.
I first started the sytem with straight water. Really felt great!
Then moved to windshield washer fluid. Not as impressed as straight water but still felt good
Then ran with straight methanol and had some incredible runs. Power was very impressive. As with all talons, then something happened and went back to straight water to rule out it wasnt the methanol. I have ironed things out and will probably try straight meth again.
There was a very long discussion on what worked best to inject on the turbo buick board.
The final decision was that water has a larger ability to absorb heat over methanol (ability to suppress detonation and run higher boost and timing) BUT, the buick guys swore that straight methanol was the only way to go and DAMN the engineers and the laws of chemistry!
And, in there defence, many of their members ran much better using straight meth then a water mix, so they did have real world examples.
Everyone agreed though that methanol:
1. Does have an FUEL octane level that water does not have
2. Methanol did not have the ability to cool as well, but did cool faster.
The best thing for people thinking about injecting, but are experimenters and would like to try different stuff, is to build the sytem to support straight meth so you can experiment from there.
Yeah I also reccommend that they use a good nozzle that turns the water, alky, methonal or whatever they use into a fine mist. This is very important. I have seen home made alky setups that just had a nozzle into the throttle body and it bogged down there entire system when the alky was injected. I suggested a fine mist NOS [tm] brand nozzle and it worked great.
couple of things to add here. my first install was one nozzle, right after the turbo. i also installed a simple switch to activate it. rev the motor, feel the pipe(it will be very hot to the touch), engage the wi, and you will feel it get cold. so, if you are at a stop, if you rev the motor and engage the wi, the entire intake, including the intercooler, gets nice and cool. also, one of the benefits of wi is the cleaning. propane and nitrous dont do this. after a couple of months, check the tops of the pistons, they will be all clean and free of carbon. spark plugs will have just a light haze on them. if you ever pull the head, all the valves, combustion chamber, etc will be spotless. if you add a bit of alcohol, the entire intake tract and the inside of the intercooler get squeaky clean. a couple notes of caution. a new shurflo pump is 78 bucks or less(i have seen them on sale for 39 bucks). and new aquamist pump is 300 bucks, and they WILL fail. the blue windshield washer fluid, not all of them use distilled water. i run a clear fuel filter inline before the pump. i was getting the blue stuff and it clogged up the filter so bad, i couldnt get it apart, and had to throw it away. it left a deposit very much like hard water. the filter did work, cause none of it got thru, but no fluid did, either.
As for nozzles, I use the mcmaster-car oil burner nozzles. Same as many other DIY kits. Excellent spray pattern and dirt cheap! Also, high quality brass.
I also have a moment switch hooked in. With the engine idling and engaging straight water, the TB elbow cooled off nicely. Running straight meth, and the the thing got damned cold instantly.
I have also started to add more straight meth back to my tank off washer fluid mix. Already starting to feel a little more kick.
I was running 50%H2O and 50%denatured ALC. Tonight I'm gonna be running straight methanol. I lowered the boost for a couple of see how it works. Did notice my EGT's were lower but this could coinside with lower boost.
I have the SMC Enterprise Kit. Got it from Fullthrottle

Will continue to experiment.
Where can I purchase these mcmaster-car oil burner nozzles you speak of? I would also like a link as I tried looking them up in google and got nothing.....
I have have added WI from Coolingmist. Good quality at a good price. Customer service was right there. This is one of the best mods I have ever done. I currently run 50/50.
this and a wideband will be my next mods around chistmas time. after that im not doing naymore modding to the 7bolt. hoping to pick up a 6 bolt block soon and start building it up. opefully ill have the $$$$ to get one of slowboys race heads to go with it
) thanx
Copied your above statement, but I am seriously interested.
