useless Member 259 Member For: 21y 12d Gender: Male Posted 27/03/07 07:53 AM Author Share Posted 27/03/07 07:53 AM 58 psi is alot.I am surpirsed.Perhaps it is necessary to overcome turbo pressures and actually flow against these figures.

For example if you had say 15PSI boost you might have @ 475~500kpa fuel pressure.

useless Member 259 Member For: 21y 12d Gender: Male Posted 27/03/07 01:58 PM Author Share Posted 27/03/07 01:58 PM (edited) So correct me if I am wrong..but 400kpa at wot = 60psi less boost psi say 9 psi would mean the injector nozzle would have an effective 51 psi..Is this right?

High aint it?It's funny though, 'cause I am running 24psi of boost and my fuel pressure reg doesn't increase on boost 24psi - it is like it has a cap. I am running two Bosch 044's so flow isn't an issue, weird.........
