is there any way to tap into the stock injectors so that the water meth operates kind of like on and off, still using the pressure switch but i am concerned on how to control the type of current that the injector needs i would rather splice into a real inj and have it operate like one than having a full blowing injector at 6psi all the way to w/e i max out at

You'd hook the injector wire up through the hobbs switch, to only allow current to pass at a certain boost pressure. When the pressure drops below the predetermined threshold, current ceases to fire the injector. Remember you're going to have to plumb pressurized liquid into the injector, how will you do that?

thinking of just running a hose straight to the inj with a very tight clamp it should work lol its ghetto but hey its part of what we do also if i splice into the stock inj to the boost switch then the inj with water/meth woudnt really be at 100 duty cyle right? but would that "weaken" the actual signal or make the stock inj not work right? thx and i promise a diy when i get everything sorted out

i worry about taking current away from the fuel injector thats running the car. thats more important than water when in boost.

the hose thing should work fine, but what about the other end into the charge pipe?

i would just cut a stock fuel rail. you can tap the end of it with a pipe thread tap and then screw in a barbed fitting. you can mount it up just like the rail mounts to the intake. if that doesnt make sense, i will draw you a pic

i thought about that but then dont really have an idea on how to bolt it down if u get what i am saying so yeah ill appreciate the pic for more options thx for all your help EP and all the others

ok in order to make this more real and simple i am starting to think using a "normal" water/meth nozzle, this will bring more simplicity and RELIABILITY which is more important, so as of right now i am thinking of wiring the stock fuel pump in a small boat gas tank (which has a Full or empty, even though not electric) and run a line to a nozzle in the charge piping no need for electricity(besides the pump) or tapping inj or something else

what do guys think or this approach?

Go to the "coolingmist" site and cost out these individual components. The nozzel, a pump, a tank, a check valve, a brass filter, a hobbs switch. I think if you were to use any of the items, it will add reliability, and the cost is less than you'd think. You can after all, just u$e your ex$i$ting wind$hield wa$her tank (but not the pump...it's too weak), because the blue fluid (the -20 stuff) in it is already about 36% methanol. With this new plan you're not tapping an injector for power either.
