Ls1--ls6 injector flow rates

[tblu92]

Question about re-working the IFR table when going to a bigger injector--When a corvette injector is rated at 28 lbs from GM--Is that rating at the industry standard 3-bar (43.5) PSI or is it at the LS1 4-bar (58 PSI) ?
I'm installing some Ford SVO 30 lb injectors for someone--I know they are rated at 3 bar ---But with LS1 fuel pressure shouldn't they be put in at 34.6 lbs ?

The 28.8 lb injectors that come in the '01-up LS1 C5's and f-bodies are at 4-bar. You can verify this by looking at a stock tune. :)

Hi thks--- looking at the stock "IFR table" it is scaled from 28.7 lbs to 31.4 lbs--on a ) 01 C5/Fbody and on a 01 Z06 it's scaled from 29.3 lbs to 31.9 lbs--makes it rather confusing---
So correct me if i'm wrong----If I am installing 30 lbs Ford SVO injectors ( rated at 43.5 psi) I would have to start out with the scaling at 32.4 lbs on the LS1 tables
Bacically a 30Lb ford Injector rated at 43.5 psi (3 bar) IS in our cars
32.4lbs rated at 58 psi (4 bar )

Maybe GM did a little fudging on the IFR to get the AFR's in line???

Using one of the conversion spreadsheets floating around, you can get a rough estimate of where to start. You will need to enter values greater than 30 because we run more pressure. Somewhere between 33 and 38 is where I'd expect to see you end up.
