Thanks forth link oncorb.
I've been looking into the possibility of water **** on my rig. And the price is awfully appeling on that setup versus snows setup.
What psi did you have yours set to come on?

About 6-7 psi. That way it didn't use any **** cruisin' around. Only came on when you got on it or was towing.

Whichever one comes with it I suppose, didn't give me an option. I figure a turbo idi is rated at 190 hp... So I rounded up and chose the 200-300 hp kit...if that makes a difference

On the road ....
So did you ask for the stock smaller nozzle that comes included or
did you request a different one that is not offered ....

Yes, I wanted the CM5 shown here: http://www.coolingmist.com/pagedisplay.aspx?pid=13NCM5&feature_key=special_injectors
The kit comes with a CM10 which I think is too big for an IDI.

wheres the best place to put the injection nozzle? i know its a bad idea before the turbo because the water hitting the turbines can damage it.

Right into the "snail" or as close to the intake as you can get it.
I chose to put the shut-off solenoid as close to the nozzle as possible to prevent any chance of siphoning which could result in hydrolocking and damaging your motor.

tks, any perticular direction it should spray?

I set mine up to spray at 90 degrees to the flow of air in the hopes that it would get the best distribution across the motor that way. Mine uses one of Russ' (type4) elbows for the intercooler, so it was pretty easy.
Looking at my old snail I think I would drill it right below where the turbo to snail o-ring seal is and direct it across the flow at 90 degrees, putting the fittings on the drivers side of the whole thing if you have room. Should get a good swirl right there. My '57 will be getting **** and it has the snail, so I have given it some thought. Didn't want to put it on the top and have it just spray straight down, although I suspect it would be ok.

I have been considering using a water injection system for quite some time but have been worried about cylinder rust or ring rust or decay ... has anyone got any answers regarding this .. or does just cooling down the engine w/o the water on get rid of it good enough to avoid this issue ... also what kind of fuel economy gains could be expected by using a kit like these ... and it is my understanding that the only reason for the alcohol was to keep it from freezing in the winter and that it isnt nessacery during warmer months or in warmer climates ... I will appreciate your thoughts on these questions ... thanks
