50# injector question

[Lucient]

Does anyone know how many cc/min 50#msd top feed injectors are at stock fuel pressure? And what is the formula to covert? Reason I ask is I have an SR ECU that is tuned for 50# injectors and Im using it with 550cc injectors and I want a ballpark correction for my SAFCII. Thanks

50 x 10.5 = 525cc. 525cc/550cc - 1 = .04
So thats a 4% increase granted the injectors are perfectly flowing exactly that with base fuel pressure.
