vortec S/C @ 8psi Fuel system

I have a vortec system on my 03 g35 coupe right now and I want to get 8 psi out of it...
What kind of mods do I NEED to change out for the fuel system so nothing gets destroyed?

Injectors and fuel pump is all you should need until about 500whp. If you wanna splurge you can buy a return setup.

I strongly disagree. I think you're off by about 100rwhp

EDIT: Unless you get some big *** injectors.

I just have a friend who has a biult TT engine in Houston and he's limited to about 550whp right now because he doesn't have a return system... That's pretty much the case I was going off of, but thought for sure I had seen over on My350 several guys in the 450 range without a return kit.

I run 750cc on 350whp, and 8psi

.... (I have a return kit also though).

i am 99% IDC out on 450 whp with my vortech with a CJM stage 2 return and 600cc injectors.

Anyone that says they are making those kinda #'s without a return are on an optimistic dyno.

Right now I'm around 450whp on max boost (9psi) and ~95% injector duty with walbro and rfs. I could still raise the pressure some on the rfs and go higher but honestly I'll be getting bigger injectors instead when I go there.
