Yes there is.

I think they are also a different style of injector, but I dont think Ive seen a JA injector in the flesh though.

Ok. Not sure if my question has been answered but there sure are a lot of posts! It would seem around 800cc/min for the black injectors. Next question my JB injector manifold has black injectors were there any other injectors in JB's? What are the gray ones from?

Import motors apparently

theres also differnet black ones too, with different resistance. best to test with multimeter to be sure

:roll: AArrr all too confusing :roll: no mark i dont think we have answered your questions :roll:

Look, it's quite simple..

JA injectors are different to JB injectors but we aren't sure about JD injectors however one lot of injectors flow in the vicinity of 800cc but is yet to be confirmed which ones although you can get black injectors or import grey injectors although how much either of them flow is yet to be determined.

well thank heavens thats cleared that up....

can anybody tell me the flow of the standard "black" JB injectors?
Also are there any other types that will fit that throttle body, maybe throttle body 12A turbo ones?
I found some green ones not sure what they are out of (or what they flow) but they do fit (ie. same style). I can dig around but maybe someone can save me some time!

:D These were the original questions red has not been answered

OK I'll kick this off!

I think, and again I'm an old fart and am pulling this from a Saturday morning session sitting at the feet of the Guru memory, :D that standard JBs flow at 88cc per 10 secs.

Now I am pretty sure the 88cc is correct but what I am having trouble with is the time figure. ie Flow over Time

I know the JBs are considerable bigger than the JAs.

My suggestion is to also sit at the feet of the Guru one Sat morning. Ply him with a beer or two and learn all things Starion. :)

Who needs Gurus. Do it yourself!
Flow as follows:
JB black 900 cc/min (2.72 ohms)
?? Green 1180 cc/min (2.75 ohms)
VR4 blue (like your selling Cookie) 585 cc/min (2.59 ohms)
Did not flow JA injectors because of lack of jumper clips to connect to the Econoseal plug. (next trip).

Now this flow test was done at 3.0 bar using TEST FLUID NOT PETROL however if someone knows what the VR4 injector flow with petrol we can adjust the numbers to suit (if needed).

At what duty cycle were those figures achieved?

I know the VR4 injectors are factory rated at 450cc.. but I have no idea at what fuel pressure or duty cycle this was achieved.

That was full on flow (no pulsing). I agree the number for the VR4 injector seems a bit high :( But we did it twice. My injectors came from Eric Petila's GroupA VR4 rally car parts bin. I assumed they were standard, maybe not!

450cc/min is measured using a timed open flow test, ie wide open. The other smaller numbers are using a pulsed flow test, ie actually doing something. A pulsed flow test is considerably more relevant to how much an injector can flow than the open test, which is why we use it.
