shit yea, another injector question. i need some to throw in for a while until i can afford the time and money for the MS and some huge injectors, does anyone know the duty cycles and idle/boost fuel pressures for 310s and 335s at 12psi and 15psi boost? i'm not interested in 440s because of the questionability of idle...but the idea is to run 12psi daily and 15psi every now and then and i'd like to know which of these two sizes will provide the better balance between idle and low boost fuel pressures (ie, below 100psi). keep in mind, i'd like to "TRY" to accomplish this with the, ahem, cartech. i dont want to spend $300 on a SFMU that ill be ditching in 6 months to a year for a 1:1 with the MS.
yes, this is very much a quick fix, or cheap way out. but if it's absolutely impossible to tune this with the cartech i can get the SFMU.

btw, i found the following:
You can run with 315 up to 14.5 psi at exactly 100 psi of fuel pressure.
Fuel Pressure - cc/min - lbs/hr - hp - cc/min - lbs/hr - hp - boost PSI - lbs/hr - @DC - hp@DC

Try and read that graph it goes right across

does anyone have this same type of chart for 335s?

EDIT: nevermind about the duty cycles, i just remembered mine are going to be 100% because i'm not using a SAFC

I wouldn't even try to manage that craptech or let alone try to dyno it. We would do a couple pulls and the fuel pressure would change without us doing anything..what pos and waste of dyno money.

When I had 335s, FMU and SAFC I could run 14psi without it running lean on the dyno. I suppose this doesn't help because you don't have the SAFC..

that's what i thought, i did alot of reading last night and some people say 310s can go to 13-14psi and others say they are only good to 10psi. then others say to get to 15psi you MUST have at least 370s. everyone either has a different opinion or has had different experiences. i wonder how difficult it will be to run 335s up to 13-14psi with a SFMU but no AFC? that would be the ideal setup for me for the time being...not to expensive, but not overly difficult to tune.

I have 315cc and I run 15psi daily. On a hot day, you'll lean out pretty quick in 5th wot. On a cold day, you'll be fine. You'll still reach 1600f pretty quick though.

that's what i wanted to hear. i'll probably just go with those then. what disc and spring are you using now? and i assume you have the bleed valve installed as well? i'll just grab the bleeder valve from the cartech so it can at least make one good contribution to the car
