#61475, "SFMU and 30lb Injector Question"


          

Just a couple of questions about that set up. I have searched the archives and things seen before as well as taken notes over the last 10 months on what other people run to compare and see what works best. Right now I have accel 30lb injecors with the large disc and short hard spring. I am running 21 psi at idle(yet to adjust pressure under boost). Any thing over 24 psi and I would get cel for too rich.

First question: what disc and spring are most of you running and what fuel pressureare you seeing around 8 to 9 psi of boost.

Seond question: The ring with my 2.72 inch disc larger than the actual disc while the other two smaller discs fit nice and snug in the rings. Is this normal or should I order a new set of discs?

I can't tune the car yet since the threads decided to come out of the SFMU with the bleed valve. It is jammed in there but I am stil going to repalce it as soon as I can find a decent used one on ebay. I am also waiting for my new downpipe from XtremeRS and the laptop software from OBD-2. Any info would be great.

when i ran the 2.72 setup i had that disk, with the biggest ring. it should'nt just sit there, theres like 5mm of space inbetween them. i run the 3.** disk now. and i use the bleed valve. i like my setup now, then before emoji

Yeah, I run 30# injectors with the SFMU. I found the biggest disc was way rich, and caused my car to studder in boost, so I tried the 2.72" disc/ring combo. I drove it for a while, and the EGT's just rose too fast. I had to revert to the biggest disc again, but I made a bleed valve for my SFMU. Works like a charm. BTW, there is something a little odd about the 2.72" disc/ring isnt there? All the others fit good, mine has a gap too.
