I preferred to design a REAL water injection system rather than just siphoning water into the engine. They use valves to mix unmetered air and water into the engine, so the leaning out of the air/fuel mixture is probably what is getting the claimed increase in mileage not the pool of water that's sitting in your intake. Statements like "makes for a sweet tune" on their website says it all.
For $300 I can build you a real water injection system that is electronically controlled and adjustable.
Don't take offense to this personally, I am only trying to save you from wasting your time and money. Aussie, I'm a little confused, but absolutely do not mean any disrespect. I'm not sure if I agree with your above statement. I believe that atomization is nothing more than providing sufficient line pressure and nozzle sizing (like your garden hose sprayer at the "mist" setting). Or am I missing something? If you do get your product to work, I believe my brother has taken a look at several of these system and is interested in adding a system to his 1.8T Passat (and he's right in the Detroit area). Let me know what you would offer for the $300

Hey Terry should I invest in one of these too? LOL
Water injection has been used with Grand Nationals by the top two guys for years. There is one dude running 30psi on a stock lower end, engine never broken down. He uses H2O injection at the higher boost levels (turned on by a boost actuated solenoid). He uses a pressure transducer to read intake prAt a given (he determined what psi) pressure the system actuates. He is running low 10's in this car (and has been in several GN type magazines too)

I wouldn't say "ask jack roush" to the people on this board. they seem to have the opinion that he is some sort of "moron" and does "interesting" things to cars that they would not do, and he they are under the assumption he has no clue how to "tune" and engine and they can do it more cost effectively with much better performance results.

Jack is : an azzhole, a cocky bast@rd, an overpriced jackazz....but he is in no way a Moron. He does things that most wouyld not even dream of. Terry is the only person with a sicker/demented mind that I know of (and I mean it from the heart Terry  )......

Whoa, I get the feeling that was directed at me... If so, I'd be happy to share my views on the Roush Stage III and Cobra R in a thread in Off-Topic or via PM or something....

that was in NO way directed at you. just a collection of overall statements i have read from threads on this board concerning jack roush and roush racing.
however, i would like to hear what you have to say concerning those vehicles... pm me

If you do get your product to work, I believe my brother has taken a look at several of these system and is interested in adding a system to his 1.8T Passat (and he's right in the Detroit area). Let me know what you would offer for the $300 pornstar, I'll take a guess at what you are talking about and say, yes, you must be confused. What I was trying to say is that there is no way the Aquatune (uggh hurts to repeat that name) system could possibly atomise the water into the intake with the hardware they supply, purely due to the fact that they rely on manifold vacuum to draw the aerated-water mix into the intake through a simple hose. i.e. no spray to create a mist. My system does. As soon as we get Marks S/C Contour sorted out, I will have an idea of what is the right set of parts to use to make the system complete and functional. For $300 you would get the Labtronics module show, pumps, shut off solenoid, water bottle and sprayer nozzles as well as instructions or for some more cash I would install it on his (your brother's)car myself. Also to add to the fire on the Aqutune system; seeing as it uses vacuum to induce the water into the engine, on a forced induction car this would have to be before the compressor unit. And from experiences of other people experimenting with water injection, water that is sprayed/dribbled into the impeller essentially erodes and pits the impeller due to the water impact at high velocity of of the impeller at boost. Not pretty!

AussieSVT, Say no more. I had no idea that brand X used manifold vacuum to introduce water. :rolleyes: I wouldn't even imagine these guys would try that, especially at the price they are asking. As an engineer, I had just assumed (my fault) that these guys used a variable pump to pressurize the water line for different rpm. I look forward to seeing your finished product and seeing a dyno chart. In fact, I'm sure my brother would love to see the car and talk with you as he had considered making a kit himself. Keep up the good work.
