anyone using it? pros and cons please

 

try the search function. Try looking under injection. Their are plenty of threads. You may also want to look at the GN forums.

 

Pros:

Better intake charge cooling and reduces chance of detonation with high boost


Cons:

Requires water to air intercooler and plumbing
Requires water reservoir


Jackson Racing uses a water mist injection system for their superchargers. Check their website for info.

 

i beg to differ, it does not require W/A IC nor does it require IC or forced induction at all. you can, and at times it is advisable to inject water, or better yet alcohol/water mixture.
cleans your cylinders a bit as well from the carbon build up.

Water injection has many methods, it origionally was designed for in cylinder cooling as the water mist was injected into the cylinder and the combination of the heat of the incoming intake charge and the heat cenerated by the compression wo evaporate the water in the cylinder, attributing to the cooling effect in the cylinder.

F-Max and other companies are using this system of a watermist injection in the intake pipe, basically the increased heat of the intake charge from the turbo is enough to evaporate this mist, accomplishing the intercooling effect on the incoming intake charge.

And something else, once the intake charge is pressurized, the evaporating water (steam)slightly increases incoming intake pressure (the is neglidageable at best, but it still is possible for manifold pressure to actually increase, although electornic boost controllers will of course compensate for this) And this is an easy method for overcoming prssure drop through large intercoolers.

Those are just a few....

 

A lot of JRSC Tegs have been getting good results from mixing a 50/50 cobination of water and alcohol. I don't know anyone that has done it on the JRSC H22a yet but it is worth a try. Aquamist seems to be the best brand for water injection.

 

If you do decide to go this route I humble suggest you design your own kit (if you're comfortable with electronics and such). I bought the smc and there are a few things I wish I were available with it. You could do a very nice system with a Process Logic Controller (PLC) setup (read. programmable on the fly) and some presuure transducers.
Forgot to add, PLC can also control boost solenoids as well so althought initial cost me look high, they are very versitile.

do you know how much aquatamist costs? I think i might try it.

 

you can get away with a custom system for around 70 bux.
