RC 310's with VAFC

if i get RC 310's for my car and a VAFC, would i still need a boost dependent fuel pressure regualtor? I know i will need a new fuel pump, kinda leaning towards the Holley 225. Im planning on running 2 more lbs which means i'll be at 10psi. I don't really care for this block, im thinking about getting a JG block anyways. So, if she goes, then she goes,,, ka-boooom =)

Yes you will still need a boost dependent fpr.Even though the 310's are larger then stock they are still close enough in size to the stock ones for the ecu to compensate for the larger injectors (the ecu will try leaning the engine out in an effort to not run to rich).Once your under boost thats when you need the fuel.Go with a 6:1 fmu and the holly 255lph pump (make sure it's the high pressure one designed for forced induction) thats what i have and it runs pretty good.

thanks man, thats what i needed to know. BUt then i was thinking, do i even need the VAFC if i have the fuel pump and FRP already? or is it just an added helper into more finer tuning?

No you won't need it but i highly recomend it.The v-afc will just allow you to fine tune your car and it will run a lot better and smoother.You will also probably make a little more power since your car will be in a better state of tune.
