L92 Injector Size?

[dtsngit]

Hey guys,

I bought some L92 heads and injectors from a guy. I'm trying to determine what size the injectors are. Here are some numbers off of the injector.

1257634
341
80526
069140255

The injectors are real short (maybe 1.75" or so).

Any idea what size these are so I can do my scaling?

I was told by one person they were around 40LBrs but then another told me 30LBrs. So I've received mixed opinions. If they are 42LBrs can you lead me to a place to find this info?

They are 30lb's.

[dtsngit]

So I've had a couple people IM me and say it has 42LBrs. While others tell me 30LBrs. Quite interesting. I can't believe I can't find any info on the net for what I have.

do you know what they came off of for sure? download a tune from repository for that vehicle and you will have your answer.

My L92 injectors have a MAX flow rate of 32.4lbs at 92.4psi. 29.4lbs at 42psi. They are the original ones and are supporting quite a bit of power. At least 500 at the flywheel.

L92 injectors are 30 lb. You do not have the complete part number, it needs to be 8 digits.

If it is PN 12576341 injector, it is the LS7 and LS3 rated at 301 g/sec @ 400 kPa, which is 39.82 lbs @ 58 psi some claim 41 lbs but this is what was on the blueprint.

Thanks! I was thinking they were the LS3/7 injectors based on my research.

Im pretty sure the truck style are 36# .

Nope, go look in the repository at some stock tunes and you will see that they are not 36's

Some people refuse to believe......30lb is just not a big enough number?

This is for my buddies 09' Sierra 6.2 w/Flex-Fuel...

I hate to dig up this thread, but I'm curious as to how the new GenIV flowrate tables relate to the older GenIII's? I know they're in a different format, but is the pressure delta a fuel rail pressure or something else?

Thanks
