fuel pressure @ 22psi

[zrolls]

at the moment i have it @ 51psi with the vacumm line unhooked. but haven't had a chance to dyno it .. i'm still running stock 35pound injectors w/ a 255walbro pump.

so what do you think a safe Bet would be at? right around this ball park ? i would think it would be more rich then lean at this point. any recommendations would be great as my AEM wideband just took a Dump on me and it's not functioning properly.

oh by the way i have all the basic modds, bobs logg, to4e, air/water intercooler w/icebox / 3" downpipe strait out. stock timing @10degrees spout out ect ect. . (currently in tho.)

just getting this beast together so this is the last thing to make strait on her...

Impossible to say without using a wideband, reading the plugs, or doing testing to see at what pressure it makes the most power. I would assume that's way too much pressure though if that's all of your mods.

so from previous experiences, other members.... their pressure ranges from anywhere from 40-48psi? (lets say from 18-25psi) would this probably be a better guess?

my car seems to pull better the higher the pressure is... it's set @ 48psi right now today @ 20-22psi.

@ 40psi fuel @20 pounds of boost it seemed to flatten the power. so i bumped it back to 48 which seemed to feel better

anybody else with a current set up like mine, what is your pressure set @?

If it pulls better there then by all means run it there.

Get a fuel pressure gauge from Harbor Freight and drive with it taped to the windshield and see what the pressure is under boost. That way you can be sure it is rising with boost as it should.
