I googled that and couldnt find anything

if you do set it up... how many passes would u be able to get out of ur fuel cell. Im no expert but i'm pretty sure u don't wanna run out of gas while in boost.... just a thought

cant you just use fuel solenoids off of old nitrous systems? If i were really wanting to do this, i would take another fuel rail and injectors and weld in a secondary set of bungs, so youd have 2 separate fuel rails and injectors, and have relays set up with boost sensing switch that as soon as you hit a preset boost level, the race gas injectors come on and the pump gas injectors cease working entirely, when in boost. Thats the only way i know of to ensure that you are getting 100% race fuel and not a race fuel/street fuel mix... even if you use valves and solenoids or whatever feeding right into the fuel rail, it is eventually going to empty the race fuel and dilute it into the pump gas tank in a return type fuel system. Plus there is gonna be residual pump gas in the fuel rail, so cyl 1 is gonna be running from the pump gas the longest because its farthest from the fuel supply side, it would be an undetermined amount of time before each cyl would be running from 100% race gas.

A car with a return type fuel system will flush the rail out on startup. Valves on either side of the fuel rail is the best option.
