V8 S/charged motor jet size?

[stevebez]

OK so planning a HFS-6 system for this motor.

8 injectors rated at 39lb/h (~409cc/min) at 3 bar, but fuel line pressure runs at ~ 70PSI -80 (so ~5bar), so flow perhaps well above 500cc I would expect, but difficult to know exactly - anyone know how to extrapolate this?

So if I am running (lets assume 500ccx8=>) 4 litres / min and running water only I should target an injector of 10% fuel flow giving me 400cc flow rate required.

Boost is at 29PSI (incl atmospheric), so net +ve boost of ~15psi (~1bar).

160psi less the call it ~30psi gives me 130psi net line pressure to feed 400cc flow so I need effectively one 0.8mm jet?

Am I on track or way off base?
