What horsepower will the LS9 injectors support at 58 psi?

I know boost plays a role in this so for the sake of this discussion, assume we have 8 lbs of boost. Also, assume you are supplying enough fuel volume too.

How much rear wheel or flywheel (which ever applies) horsepower will the LS9 injectors support at 58 psi on a motor with 8 lbs of boost?

I have 568 RWHP & 539 Ftlbs RW and I am good.... I am sure you can do better. I have heard 600 ish

With 15% DT Loss ( LS3 ) I figure I have about FLW652Hp & 620 FtLbs Tq FW at around 9 PSI of Boost with a maggie and full exhaust.

Fuel pressure is between 58 and 59psi constant ( DEUL PUMPS INSTALLED)
