    Contact Lingefelter, they should know, they are a supporter of this site.

    I would expect around 27-30 lbs/hr. more like 27-28 tops.

    Out of curiosity, why do you want to know? Unless you are signifantly (turbo, supercharger, N20) stock can handle nearly anything. Fatter injectors will likely slow it down unless you can use the fuel somehow. It tosses off the BLM values by a bunch.

    According to the 2005 GM Performance Parts catalog, all LQ8's use 25 lb injectors. Most, if not all LS1's (5.7L) and LS2's (6.0L) also use 25 lb injectors too. Info is still scarce on LS7's. But they are likely around 28 to 30, with 30 being the high end.

    Strange, I posted 24 lbs, and it changed it to 25 lbs..... Weird.... Admins keep setting up strange text changers on this site....

    I know, I have the 01 stock LS6 injectors in my LT1, stock settings apply.... No mods needed to the tune...
