Well,
Seven months and no help. Here is what I came up with using 10% WI to fuel use as a rule.
My 72 lb (~720 CC/min) injectors do not flow over 50% duty cycle right now at 12 psi. (720 X 6 = 4320 cc/min) X .5 = 2160 X .10 = 216 cc/min required for the nozzle for 10% of the injectors 50% DS. The 1mm nozzle can flow up to ~320 cc/min. This is good because I do not want my WI pump having to operate at 100% DS to keep up with the fuel delivery.
