Extremely loud 19# injectors?

[ForcedFirebird]

i told mark my setup and he made me a chip, though he lives in cali so it really hasnt been tested

after the ecu resets it runs crazy rich but after a few minutes of driving it levels out more, again i can tell you more once i get the wideband installed, but im very busy/lazy

You can pull the Mv off the stock o2 if you have a digital milti-meter, just won't be very accurate compared to a 3-wire or better yet a 5-wire sensor.

Nope, Turbo built to super 60 specs (allmost), ForcedFirebird, what kind of firebird do you have.

1990 with a 60 degree V6.

stock fuel pressure (afaik) with a purpose built MarkD chip, though undynoed

You had someone tune your chip, or was it a "mail order"?

i wouldnt doubt the rich comment though

they are a little underated. my 19#s flowed about 20.5#. but it also depends on the fuel pressure you are using..

Exactly. Ford uses a lower base fuel pressure, so when a Ford injector is used in other brand cars - they are delivering more fuel.

I just installed a set of 24# injectors on my Firebird and they are loud compared to stock. (I know this doesn't have to do with my BMW, but same scenerio)
I am assuming you got the orange top Denso's or Bosch?
The Ford/Bosch are under rated. The 19# flow more like 21 and the 24's are 25.5.

edit: and yes they are orange topped from ford i think theyre bosch, i want them to shut the hell up

Ain't going to happen. In fact if you meter your o2, I would almost put a penny on it that your running rich. Are you running the stock tune?

EDIT : The Dodge is probably a 2.2 turbo and 52# are a little thick for that engine, unless there are some hot mods...
I'm sure I'll be upgrading before too long - I'm going to run out of injector at about 255HP (might be able to squeeze a little mor with the FMU, though).

That seems a little low since i got ones that flow 52 lbs/hr in my 2.2 dodge. But i looked up #19 inj. lastnight and it said they flow 19lbs/hr.

yeah, # is called the pound sign, so 19# = 19lb ;)

In the E30 they are supposed to flow 19lbs, but in the E24 and E28 I guess since the pressure is higher they flow almost 21?
