98839, 550 with sfmu and safc?
Posted by Slo2g, Jan-11-07 09:42 AM

Is it possible to run 550cc's with a sfmu and an safc? I have been researching and can find where people THINK that its not feasible(sp?). I want to know, can or can't I run the 550's with the sfmu and safc. Please let me know.

How was idle and what was fuel pressure at idle?

So apparently 450's will work with fmu setup?

idle was smooth, i had leaned out the idle by like 35-40% i think it was, i dont exactly remember. and if i recall correctly, idle pressure was like 12-14psi, lol.

Yeah 450s will work. I was just wondering about 550s because I can get a good deal on them. I just don't want to run too low of fuel pressure for fear of idle. Has anyone done it with 550s?

Your going to end up selling them to get smaller injectors so don't waste your time.

You have absolutely no need for inj that large.

EDIT: Hence your sig.

If you do the resistor pack you can run 4g 450s. They can be found for faily cheap. You have to use the 420a o-rings though.

Yeah I just bought a resister pack for the 450s.
