Water injection for a supercharger application:

It'll reduce the chance of detonation and could add margin to your fuel delivery system.
I suggest a decent ignition amplifier modification.
It's something I would add if you have detonation with the stock pulley or upgraded pulley.

Great feedback from the turbocharged guys on DSM and Mazda forums.

The 2D system is plug n play with it's own map.
The 2S is a fully programmable kit that requires some tuning.

I looked into an Aquamist system a while ago but never actually followed through.
The biggest issue is where to put the water injector. The water would have to be introduced AFTER the impellers.
I had a few local hot rod shops look at my engine and they said they could either tap into the housing after the impellers or fab a spacer with the injector to place between the blower and the intake manifold.
Like I said, though, I never followed through.

 

Ajatx,

Are you planning to do it? There are a few of us discussing this option as a great way to run a 9 psi pulley without the negatives and the potential for 300+HP to the wheels. What did you have in mind? What generation S/C are you running?
