LS9 injectors on the LS3?
LS9 injectors on the LS3? Anybody running LS9 injectors on an LS3 with the stock intake? I've heard so many mixed opinions. Some guys have ran it with no issues, but others that have said its not a good idea never said they had issues with it. Just looking for real info instead of random forum reading. I understand that the spray pattern is different, I've seen a handful of guys use them with no issues.
Let me know if it has or has not worked for you, and what issues you had if it did not work.

I ran ls9/LSA injectors in my LS7 intake on a 427 street/road race setup. Mostly running e50 blend of 91/e85 controlled by Holley HP EFI.
No issues.... Went 111mph best in the 1/8 and 138.3mph 1/4

There's debate over the spray pattern due to them being tailored for a supercharger. Something about the way the mist/cone of fuel comes out. I personally wouldn't run them. Just because people "get away" with it doesn't mean it's the right tool for the job. Maybe those guys would make more power or run "safer" if they used the correct injector that fully misted the fuel into the chamber / rummer? It's just a thought.
You have an LS3, yes? Why not just send them to FIC and have them re-worked for whatever YOU need? It's like 30 bucks an injector and they're fully matched at that point.

Send them to FIC? I had no clue that I could do that. FIC stands for Fuel Injector Connection?

Verdad Gallardo Correct. Connection - The one in Georgia, NOT FIC Fuel Injector CLINIC.
That's what's going on my CTS-V.... Stock LSA injectors that have been reworked to be 72#. Tuners love them bc there's no mystery to them; it's still a GM injector.
BOOM!!

I appreciate you sharing the info! I'll give them a ring!
Good article from 2012... Very familar with ID and if I had the coin, I'd run them. There is however nothing wrong with running a resized injector if you have the DATA to support them, and if they themselves are flowmatched before being sent out the door.
I trust my particular tuner over anyone else in this industry and while ID is his first choice as well, FIC was his second.

As Stated I ran them on the street/drag and road course and they were great. Run them... And if you feel they don't perform then search for drilled or other options. The LS9 perform well

I agree. I wouldn't want to be over 90% on them, that's for sure. I usually try to keep it around 80% IDC at WOT.
I still think ID850's are way too much for a simple pulley LSA combo.... When you're hitting only 55-60% IDC @ WOT, I can't imagine what off-idle must be like.

I didn't mean the edge as in duty cycle. More like pushing the timing to the edge and having to trust the flow rate to be precise so the PCM can calculate the correct pulsewidth. Where being a few % of on fueling leads to melted pistons and/out cracked blocks.
