FPR as FMS for Turbo Project???
 

I was thinking...how many PSI do i really need to fuel my injectors? how many psi of fuel will the safc give me. I think i have 240cc injectors now. and i will be installing 390cc injectors. couldnt i just use a FPR to give me fuel system the fuel it needs? and not buy an SAFC...am i right? because i know that the injector cc to psi conversion is like for every 9.9cc = 1lbs/hr(something like that) so can i just use a FPR to fuel my injectors? and then i would have to buy a new MAP sensor...right? because doesnt the hack trick the sensors? ???

you have more posts than I do so you might know more than me since Im knew to this ---- but I think a fmu and that size injectors is going to flood youre ----.a few buddies of mine run fmu's on there cars with factory injectors(240cc)at 8 lbs and there cars do fine.I would saysince we both have the same car ---- the fmu and ---- the safc because there both going to cost more then uberdata and give you lest for youre money.uberdata and 450 dsm inj. and you can fine tune youre ----.but then again Im a newbie so what the ---- do I know :-X

you dont want to turn up the pressure with 390s. go out and get 450s and either use uberdata or an afc to turn them down. btw: an afc does not turn up the fuel pressure

fmu rasises fuel pressure
afc controls larger injectors

Re:FPR as FMS for Turbo Project???
 

see i dont want to run an FMU, can i just run a FPR(fuel pressure regulator) and compensate for my injectors?

Re:FPR as FMS for Turbo Project???
 

no...you are missing what im saying. If anything, you need to turn down 390s, not up. But using an fpr for fuel management is a horrible idea.

well i want the cheapest fms...so can i use an fmu, and what is the ratios mean again? (ever 1psi of boost = 12lbs of fuel? right? ANYONE EVER USE AN FMU VS AN SAFC???

Re:FPR as FMS for Turbo Project???
 

from what I beleive its fmu and stock injectors or bigger injectors and afc or uber .do you mean fuel pressure regulator as in the one that goes on the fuel rail?if thats what you mean Im not sure that would work.I think the car would go lean unless you had a real low boost setup and I still dont think that would work.stop being cheap cause itll cost you a motor in the long run and a ass load of money.uberdata is only costing me 110 with datalogging port base map to get started .and another few bucks for dsm injectors and thats still lest than what I payed for my knew vortech fmu($170).I think thats a bargain since you can tune your ---- yourself with a laptop.some people even do it for a little less but all I wanted to do was plug the ---- up and get it tuned.
