Newbie question: Has anyone flow tested a stock injector?

I dont need to verify it, since TS has already done it.
if you dont believe me, or the service manual, or nissan that are reiterating the same data... additional testing is pointless.

Cheston,
Would you mind sending your injectors for dr_gallup to verify that PLEASE?

FSM gives flow data for the injectors? Where?
TS testing method may or may not be valid, how would I know? I haven't seen anything other then what you've stated, which are TWO different things:
1)"290cc at 3bar", which is dumb since the VQ35 fuel system operates at 3.5bar.
2)"my tuner did a flow test for my stock injectors on the VQ35DE on my Z.. we only got something like 300 ish.. and with my TT kit we saw 95% duty cycle with the stock boost on the turbos."
So, Nissan is reiterating the same data? Where?
Nissan parts catalog, FAST CD, along with numerous parts websites say that the 222hp VQ30 Maxima and 287hp VQ35 in the 350z use the SAME injectors, *YET* the 255hp VQ35 in the Maxima has different injectors that HAVE been flow tested by RC Engineering to put out 270cc@3bar and 315cc@3.5bar. Now does that make SENSE?!?!?!?
No, so I do consider additional testing NOT to be "pointless". A simple no reply to my emails is better then none and then calling it "pointless" is stupid.

Well I received an email back from RC Engineering and they confirmed that the 350z and the 222hp VQ30 Maxima injectors do share the SAME part number. Like you guys care!
Anyways, they've flow tested them to 295cc@3bar and now as a Maxima owner I'd like to THANK YOU 350z guys for giving us a CHEAPER alternative to custom injectors.

not sure I understand what didn't make sense here. The standard for testing injector flow rates is, and always has been 3 bar. Of course as you increase pressure, to a certain degree, flow increases too. So what was so surprising that RC Confirmed? Seems to be the same exact info Cheston pointed out ages ago................
