28.8 injectors @ 4 BAR are good to 420>450rwhp (~ 520 fhp) depending on fuel pump pressure (assuming it is steady 58 psi)
The variation is due to the fact that f-body pressure regulator is in the back (by tank), and doesn't garantee 58 psi at the rail. Racetronix comming up with rail reg. that would cure that.
Keeping in mind that one should stay in the 80% max cycle.
I have a PnP racetronix fuel pump kit that gives me 62 psi and 58 psi @ WOT. (you can see 4 psi drop)
Combined with SVO 30's (35.4 @ 62 psi), I'm able to run 400rwhp N/A + 200 shot dry for a total of ~560 rwhp at 83% duty cycle.
