that makes more sense i wonder where you got the idea to run two nozzles on staged injection 
Im curius as to the amount of pooling etc you get. Theoretically if you kept the spray off until you hit a higher velocity say 13 or so psi it should all keep on moving until your done with it in the combustion chamber.

I don't wanna splurge on a real progressive kit, and already have a "Y" fitting.
I'm thinking about using 2 pressure switches and 2 solenoids. Main nozzle after IC comes on at 8psi, and a smaller nozzle pre-compressor comes on at 10psi to shift the map a little.
With my hustler-*****-sized turbo I would definitely not mind having 12psi at something better than 60% efficiency for once.

That's really interesting, and I'd never thought of this.
