720cc with SAFC question

[Mitsu2nv]

Alright ive heard from some people that with 720cc injectors that my idling will suck if im using them with a SAFC
is this true?
becuase ive also heard that it doesn't
i don't know who is right or wrong
im planning to have 400whp are they too big or should i go for 660 if there is a problem with 720cc with the safc
thanx

all you need is 660cc injectors 720cc are just to big for 400whp

Ive got 720cc Densos and an AFC. My car idles fair. Ive also got a vented Apex BOV. I'll let you know how it idles after i stick in the HKS 272s

I have the HKS cams, 720's and an AFC. My car idles just fine. 660's or 720's should be fine for 400whp. I plan on making between 400-450whp.

The problem with a S-AFC and 720 is that you will not be able to lean out your car enough and you will run very rich unless your running a large turbo. I would not run 720 unless your planning on running a Green or bigger than that. And still that may runn too rich.

Im running them right now on my small 16g before the L3R goes in friday and Im not seeing much of a problem.

I'm using 660's on a big16g and I idle just fine. 720's are very big; you could should be able to use 660's. What turbo do you plan on using? Like it was said before, you might not be able to lean the 720's out enough up top.

I have a S-AFC easily controlling 680's.
