If RC Engineering flowed our injectors with their test fluid @ 43 psi, they would rate the injectors as follows:

2003 Injectors - 343.3 g/min = 45.3 lb/hr = 498.3 cc/min
2004 Injectors - 377.6 g/min = 49.8 lb/hr = 547.8 cc/min

I posted this above. All you have to do is plug the 547.8 cc/min into the equation orignally posted and then you will have your number. The tools are here, put them to use.

so someone deleted my post, thats cool.
again, for, hell, i dunno how many times this makes it. i am referring to 58 psi.
58 psi is the pressure that the srt-4 runs in stock "trim". I'm not asking about 43.5 psi. if i was asking about 43.5 psi i would be retarded because it's already posted in this thread. really, do you think my reading skills are that bad? if you do you might want to reevalute your own because as i stated, i wanted to know 58 psi. i've said this now in every thread where i asked. and in this thread a few more times. 58 psi. that would be swell. rc uses a different fluid density to rate their injectors. im curious to know what the s1 injectors would flow at 58psi using the same fluid density as the rc's do.
that is all, nothing more nothing less. perhaps this post won't get deleted as well, i can't be any more clear.

I figured you could do a couple of simple math operations and take the initiative to figure it out on your own, but since apparently you can't I went ahead and did it for you. 30 seconds and a calculator could've saved you all this typing and wasted time. Here you go:

632.5 cc/min

and as much as you hated wasting your 30 seconds for me i have to say that using that number in the e-manage injector correction has made quite a difference for me, and i again thank you.

the car seems much happier with 630 punched in, it doesnt dip so rich like it was before and generally seems like its running much better.

i'd still like to know how PSI-FI is saying that the injectors they are selling flows more than S2..

Wait a min.....

So your saying that the S1 injectors are at 632.5cc when the RC 650's are at 650cc, since all variables would be equal at those numbers??? WOW. So basically S2 injectors are bigger/more cc then the 650 RC's?

I am lost here.

Heres my question....

ALL variables equal... Whats the flow rate of S1 inj and whats the rate of RC650's?

Thanks

I thought they said the 550cc(43.5psi) injectors flow better than the stock 2004 (stg1) injectors that are 577cc(58psi) which they in fact do.

Or did I miss that post?

As posted at the top of this page:

If RC Engineering flowed our injectors with their test fluid @ 43 psi, they would rate the injectors as follows:

2003 Injectors - 343.3 g/min = 45.3 lb/hr = 498.3 cc/min
2004 Injectors - 377.6 g/min = 49.8 lb/hr = 547.8 cc/min

So theoretically, the stock 03's are ~500's, and the S1 injectors are ~550's by RC standards. The RC 650's would be...well....650's. The 630 number I gave was the conversion for 58 psi. Without doing any calculations, it appears as though the S2 injectors would be in the 640 range by RC standards.

thats odd then. Cause that would mean that a S2 car (really not that much different then a S0) at idle see's a really close amount of fuel as my S0 with RC650's? why is it then that my 650's caused my car to vertually not idle?

It would make sense that the the S2 ECU (which you aren't running) will be calibrated for the larger injectors - hence it idles properly.

Nevertheless, I've seen S2 cars which *doesn't* idle properly. Seems like it's missing (even though the plugs, wires, coilpack got replaced with new ones).

Good post...now I see the extra power the 750's will afford me.

as soon as I put on S2 injectors my idle did exactly that. I've pulled and checked everything. Nothing makes a difference at idle...now at WOT they perform like absolute champs. I have fuel for days @24 PSI with the return system.

might be a dumb question but why do stage 2 and stage 3 have different flow rates if there are using the same injectors??? i dont think the new fuel rail could have changed the flow.
