flow tested injectors
flow tested injectors
I recently had some red top injectors from a nissan 300zx flow tested at a local shop and the test results for the injectors was in ml's over a 30 time period. for example, one injector was 110 ml's/30 sec. does anyone know the calculations i would use to convert that to cc's?

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Re: flow tested injectors
lol, yeah, i get that, but are the cc's of an injector ussually measured over 1 min?

Re: flow tested injectors
i moddified these injectors and was expecting to be in the 550 cc range.

Re: flow tested injectors
Seriously man?
110cc/30s equals how many cc/60s?
Did you pass grade school math?

Re: flow tested injectors
Usually they are tested at 43psi to find the static flow. And those results come in cc/minute.
From this, your injectors are at 220cc/min. Unless your guy used a different psi to test them at..
OEM N/A 300xz injectors are rated at 270cc, and the TT version are rated for 370cc.

Re: flow tested injectors
thanks Pox...i'll find out what pressure they tested the injectors at

Re: flow tested injectors
I'm still confused about it.
Is it just a related rate, or is there something more fancy with PSI?

Re: flow tested injectors
Manufacturers rate fuel injectors by the maximum amount of fuel that they can flow in a given amount of time at a given pressure. This measurement is known as Static Flow Rate and is normally taken at 100% duty cycle and a fuel pressure of 43.5 PSI.
Example: At 100% duty cycle a 55 pound (lb) injector at 43.5 PSI of fuel pressure will flow 55 pounds per hour.
Injector Flow Rates are expressed in pounds per hour (lb/hr) or cubic centimeter per minute (cc/min). Given the same pressure 1 lb/hr = 10.5 cc/min.
To convert lb/ hr to cc/min, multiply by 10.5
Sometimes injector flow rates are expressed in milliliter per minute (ml/min)
1 ml = 1 cc
Example: a 220 cc injector = 220 ml injector

Re: flow tested injectors
Ok, so I spoke with the tech that tested my injectors and he said when they tested them, they hooked them up to a series of pulses for 30 secs rather than full flow. That's why the results were not what I was looking for. Btw, I was really wondering what 110 x 2 was, I couldn't find enough people to count that many fingers and toes. Thanks with the math help ![Wink :wink:](./images/smilies/icon_wink.gif)

I have a profound distaste for library computers now... I'm not spamming the submit button, but these things are so messed up it thinks so anyways. Also, how do we delete posts? We used to be able to.

Re: flow tested injectors
What year and engine type Nissan 300ZX did they come from. Once that's determined it's easy to find out exactly what size injector they are.mx3stylez wrote:I recently had some red top injectors from a nissan 300zx flow tested at a local shop and the test results for the injectors was in ml's over a 30 time period. for example, one injector was 110 ml's/30 sec. does anyone know the calculations i would use to convert that to cc's?
