Injector size in lbs/Hr = Expected HP x BSFC / # of injectors

use .55 for BSFC(BrakeSpecificFuelConsumption)

To convert Inj.'s to CC's=[(Inj size in lb/Hrx454)/60]/.75

how much HP do you realistically want with this setup? plug that # in to 'Exp'd HP' and as long as the injectors are a little big its ok just dont be short. be sure to convert to cc's.
sorry dont know about VAFC.
