FMU Ratios and injector sizes

[Ackbar00]

If it is 12:1 and you have 6psi of boost this causes the FMU to raise fuel pressure to 72psi, right ?
Well, It raises 12 PSI for every pound of boost, so it would add 72psi to your static pressure. But this is WAY too much, Try a adjustable FMU, that way, you dont have to screw with disc.


Is this 72psi in addition to the factory regulators 38-40psi ? Yes

Also, what size injectors would be recommended for a stock cylinder head 302 running 6 psi,GT40 intake, 65mm throttle body, 73mm MAS, 1.7 roller rockers, 15/8 equal length shorties, and dynomax exhaust?If you are going to run a FMU, just stick with the 19#'rs. You be fine with at 6#'s

Should I ditch the FMU and go with a tune ? What is everyone's opinion ?
That is always the best approach.. But I am runnig 30# injectors with a BEGI FMU. Should make over 400 RWHP when it is all said and done.
