I plan on running the Hondata system with 450cc DSM injectors at 8psi on my DRAG GEN III GSR (Let's say 270whp @ 12.2-12.7 A/F). What is the max safe fuel pressure that I can run on the stock fuel pump without having to either upgrade the pump or add an inline pump? I am currently running an inline, but would like to know if I could take it out it I keep by fuel pressures below a certain point (and what that point is).

 

I belive max. safe pressure limit for stock pumps is about 50-55psi @ WOT

 

So if I increased my base fuel pressure to 50psi and used a 1-1 fuel pressure reg. I would see ~58psi of fuel pressure at 8psi of boost. So my stock fuel pump should be okay (58psi is close enough to 55psi)?!!? Now what would me fuel injector duty cycles look like at this presure? Is this too low?
