Two stage WI system?
I was thinking earlier today about trying something like the following.
Have once WI system, but two boost activated valves. Once set to 1 or 2 PSI with a 350 or 400cc injector and the other set to 12PSI or so with a 300cc injector.
Have a "switch" to choose which one you want to use depending on how much boost you're running.
For instance, I typically don't run more than 10PSI on the street. For that, I can see 350-400cc starting at say 2PSI to be sufficient. But that's not enough water for higher boost, and you can't run 650cc of water at 2PSI since it will most likely flood your engine.
Then at the track, or if I plan to go for a "spirited drive" I can have both my boost controller set up along with the WI system to one switch. First switch would be the "low boost" at 10PSI with a 350cc injector, and High boost would be 15PSI+ (yet to be determined) with an additional 300cc injector coming on at 12PSI in conjunction with the 350/400cc that was already spraying from 2PSI.
Get what I mean?
Has anyone done this?

That is overly complicated. Just run a boost switch for each solenoid. If you set the second boost switch for 12 psi and you are never boosting past 10psi on your low boost setting the injector will not come on. When you raise the boost with your boost controller past 12 psi you will get the extra WI over 12 psi
