Thread: RRC 3.9 Injectors flow rate?

3.9 injectors(green band) flow 23.5Lbs per hour at 2.5Bar , vs Commodore iron V8 at 18lbs per hour. They can sustain a 4.6 .

Thanks Philip A . Have just found these....

Stan Weiss' - Electronic Fuel Injector (EFI) Flow Data Table.

Just need to make sure resistance is in range for the Haltech since I should only need 240 ccs with the blower the 3.9 injectors may be ok. If I can't stop it leaning out will look at higher flow rate then.

Cheers Tony.

But did you find the 3.9 injectors on the list?
I couldn't see them.
I cannot remember now where I found the info because it was years ago.
In any case I would not be buying them now aa they are very old tech.

I haven't had the time to find the part numbers, so not sure if they are on the list yet. Have considered using HSV v8 dunnydore as alternative???

OEM part no looks like ERR 722
So called 3.9 on 1st chart Prt no 0-282-150-556 but as most after market Flow less Seems ford injectors are a popular choice.

Also had a look at Bosch Injectors - Alpha Romeo, Fiat & Jaguar Fuel Injectors That PhillipA had posted in another thread.


The Delco/Haltech fuel management is high impedance like 14 cux so I have some options with Injectors flow wise.
