Injector Fow rate.. I looked at the spreadsheet for calculating the Injector Flow Rate. Other than the size of the injector ( 42# SVO's )and the fuel rail pressure, where do you get the injector flow pressure rating from? or is there a calculation you can do to find this out? On the example given..it uses 30# injectors and a fuel rail pressure of 58 psi. Where does it get the injector pressure rate of 39.15?

Re: Injector Fow rate.. Someone must know???? If I leave the 39.15 value in and just change the injector size, is this OK??
Also In LS1EDIT when you make the numbers higher in the INJECTOR FLOW RATE chart does that delete more for or add more fuel?

Re: Injector Fow rate.. Standard Injector Test Pressure is 43.5 PSI.
But SOME Ford SVO Injectors are claimed to be tested at 39.6 or 39.xx (or thereabouts).
If you can't find concrete answers, try one, then try the other, and use whichever one brings you closest to negating/zeroing LTFT's.
It really doesn't matter... just start somewhere close and lower (more fuel) or raise (less fuel) the Inj Flow Rate table until you are close to zero on LTFT's and you can confirm your LTFT's zero out at WOT.
