Possible WI solenoid solution?
I know that a few people here have considered using their standalone engine management to try to control the pumps on the WI kits out there without much success and the Aquamist WI solenoid is $$$.
I was doing some searching and found this: http://www.alamomotorsports.com/FJO/waterinjection.htm
If you look at the parts list, there is a stainless steel, high speed WI solenoid for $127.25. Haven't looked into the specifics, but sounds similar to the Aquamist one. Might be promising in terms of WI that is controlled via an injection solenoid rather than a pump pulse. Basically, you'd need a high flow pump, methanol/water tank, and some odds/ends in terms of tubing/check valves, etc... Then control the solenoid via a PWM output?
Just a heads up to those considering it as I am planning on checking this out some more when I get the time.

why don't you guys buy a "normal" Nitrous/Fuel Solenoid?
These are stainless steel too, can stand the pressure (Nitrous one is rated for 3000 psi) and they're much cheaper...
They use standard 1/8 or 1/4 NPT Fittings and there are modules sold for the purge solenoids (the one you use to relieve Nitrous from the car) to open/close them ultra rapidly to have a maschinegun soundeffect...
they work with 12V, they can open/close really fast so it should work?

I think the "fuel" solenoid from a nitrous kit would be better than the "nitrous" solenoid. Nitrous solenoids require more current to drive, which is ok if your standalone/piggyback has high current drivers. My AEM EMS does not so I have to use fuel solenoids, which have similar resistance to a standard saturated type fuel injector (~16 ohms). They should still be able to handle the pressure.
While I'm not sure if a fuel or nitrous solenoid would handle the environment, the FJO solenoid looks just like a nitrous-kit fuel solenoid. And I know you can get a fuel solenoid from me or Summit or whomever for around $65. MSD's solenoid for their water injection (for injecting corrosive salt water into exhaust of a jetski, again looks just like a fuel solenoid) is around $95.
Either way you'd have to use a PWM output, not a injector output due to limitations on frequency capability of the solenoid. Aquamist solenoid is the only one I know of that can handle the hertz of a fuel injector.

Hell, here's a good parts list for a DIY WI kit. Put together by one of the best tuners in the Suby world.
