I'm using my alkycontrol kit to spray straight water now, just trying to use it for cooling at this point rather than octane boosting. How do I know how high to turn it up? With a 50/50 mix of water and meth I could keep my 1/4 mile end IAT's within about 5 degrees of starting IAT's. With straight water on the bigger motor they are still rising by about 25* between start and finish. After a run I took the filter off and felt up in the intake tube and it was a little damp inside, but there was no standing water. How much should I turn it up? I think I can crank it up more but I don't want to suck un-misted water into the TB. Not sure if I should be concerned with the inside of the intake tube being a little damp.

 

Youll feel a loss in power soon as its sprays if theres to much.

 

Yep, run it up until it bogs and then back it off a touch.
