Re: stock fuel pump limit
My stock fuel pump maxes out at around 6 psi with *L* of all things a stock evo8 turbo. that I love totally worth the mods to make it work. and 510cc injectors. so i'm only running 4 psi right now until I get my new pump in. And I have a few other issues I'm working out before I up the boost to 10psi.
I got a xenocron pump as well. I can't wait for my Ostrich to get here.

Re: stock fuel pump limit
I'll pretty much repeat on what Quadnie and Minor Threat said...rewire. Have you guys actually seen the stock wiring up close and personal? You'd be lucky if it was a 16/18g wire. 10g wire on a stock pump makes a difference. Hell, I even run a walbro 255lph with a 10g rewire. Just make sure to turn your rail pressure down.

Re: stock fuel pump limit
Damm WTF you are making sure everything is perfect. I respect that. Whats crazy is you will do all this research, upgrade the wiring and the fuel pump, and then when your putting in the new pump you will be smoking a cigarette next to the open tank in car FTW!!!
