need flow rates for 850i fuel injectors

[der affe]

here is the part number:
0280150715

i tried to google it, but i only find them for sale with no info.

also do they make them in a 4 pintle design?

BTW this is what comes stock in the Dbilas ITB's and i would like to get another set and have them balanced and cleaned is you happen to have a set of 6 on the cheap

[der affe]

anyone???

how about an 850i fourm to search in?

www.clube31.com might point you in the right direction!

cool, thanks!

Dbilas told me that they were 42lb injectors, but i would like to see what i can find in a more modern design and i doubt they have updated the inj for the 8'ers

[whodwho]

They are 14.5lbs/hr - 152.4cc/min

thanks.....and shitty!!!
i guess the PO changed out the injectors to these, amoung other stupid stuff he did that i have had to fix on the car.

i guess i am swapping in the 26lb'ers to see if it makes a difference on the power this weekend.

What are you running for management?

[einstein57]

26lb injectors is a lot of flow. Are you at least 3 liters? If not id stick to the mustang injectors. The are cheap and easy to find too.

Are they Lucas, black with a green(ish) stripe?

the are actually 4 pinstil and rated at 28lbs @ 52psi of fuel pressure
being an "i" my car runs at 43psi. that should put me at around 24-25 lbs on the injectors.

the motor is a 2.7 stroker, 292 cam, mildly ported head, Dbilas ITB's (which come from the factory with 42lb injectors, so i am going by what the designers meant them to have, or as close to it as i can get for free/cheap), shorty headers, split second MAF and ARC-2a signal conditioner, no cat, cat back, cold air intake with heat sheild.

i am going to talk to split second on monday to see just how much the signal conditioner can shorten the pulse width of the injectors.

i also have a set of 6 pinstil 22lb injectors comming to me next week.

i do see a WAR chip in my future though.

no they are not the lucas disc type, they are actually bosch PN

this was helpful to find out the flow rates and part numbers too

http://injector-rehab.com/kbse/flowrates.htm

and according to their chart what i have is now is:

180cc per min 17lbs hour @ 3.0 bar

what i am going to is:

270cc per min 26lbs hour @ 3.0 bar

the worst it can do is run too rich and i can't adjust it to work. then i swap in the 22lb injectors and play with it and see how that works

[whodwho]

That looks like a nice injector info page I will have to use it and see how it compares to the one I have been using:

They do show different specs on your original injectors mentioned...and really differ in the 2nd ones???

I am running similar injectors(26-28lbs) you will be trying and just maxing them at 225ish whp so you have room with those if you can get them to run with your current management but the 22s are probably a closer match to your current needs.

that is the nice thing about knowing people who are not into BMW's, what is stock and useless to them, therefore free or close to it, is useful to me ;)

Drive your car to Tucson so I can see it.

i am actually going to be adding an M-90 to mine as well (i know that you are using the paxton) so if the 26-28lb'ers are too much for the N/A motor, i can use them when i get everything fabbed and installed.

i want to get everything fetted before i do the M-30B3.5 swap with the M-90, ITB's, EMS, and H2o to air intercooler figured out so i can just adjust placement and routing of the pipes to meet the new motor location.
