I was wondering how people using 8 injectors size them for their application???

For example:
An engine running 4x Greys = approx. 2012cc flow

therefore to switch this same setup to Run 8 injectors........???

I guess you could add the second set and keep the greys, but is there likely to be any better configurations of smaller/larger injectors or larger/smaller
i.e. 50/50, 60/40, 70/30, 40/60, 30/70 etc etc..........

Would you want the first set of injectors to provide enough fuel upto the point of Boost start such that the second set then add to this at that point???

I hope you understand what im trying to say..........
