Thread: 72lb Injector Startup IFR

  1. #1

    72lb Injector Startup IFR

    Just completed installing heads, cam, Supercharger (10-12psi), LS2-90mm/LSX and other goodies on a 427 stroker. Using 72lb injectors. Looking for approximate IFR settings to safely start this thing.

    I've tried several of the spreadsheets out there and they are either in g/sec or lb/hr. Just need something to get started then tune.

    Thanks

    The one redhardsupra has on his site is very good. I believe the link is in our sticky here.
    It doesn't have to be perfect, it just needs to be done in two weeks...
