How Do I Tell My Avg Injector Cc?

[mr_rbman]

just had my r33 gtr injectors cleaned and flow tested. I know that nissan rate them at 444cc but i have heard of people when they get there injectors cleaned and flow tested they are infact rated at sometimes 470 - 480cc, was just wondering if anyone could tell me what mine may be rated at?

The timed open flow was 110mL p/sec across all 6 injectors and the timed pulse flow was 55mL p/sec across all 6 injectors also, if anyone can tell me the average cc from this information it'd be great!

Cheers!

The GTR injectors are rated 440cc at 36psi fuel pressure.

At 43psi they are rated to flow 485cc.

Mine flowed 480cc at 40psi.

I've googled ml's per sec.. No idea.

Where did you get them flowed? How much?

a 440cc injector flows 440 cubic centimeters of fuel (a cubic centimeter is 1ml) per minute as i understand it, at a certain pressure. so a 440cc injector produces 440ml of fuel at the rated fuel pressure, but i'm not sure if this is measured at 100% duty cycle (injector is open all the time) or at a pulsed cycle somewhere below that.
