Thread: Injectors Auto-Phasing

    Default Injectors Auto-Phasing

    Hello. I'm hoping someone can enlighten me on this. I want to take advantage on auto-phasing my injectors. I have my camshaft profile, however, I have a problem with Injector Placement. I'm running a 358 small block Chevy with a BDS 871 blower with two 1200 CFM throttle bodies. 8 injectors rest inside fuel rail under the throttle bodies, which sits on top of blower. My question is how to calculate or figure out the distance for Injector Placement? Thank you.

    "Injector Placement - Straight-line, linear distance of the fuel injector from the intake valve, as measured or approximated from the injector outlet tip to the valve seat opening, in inches."
    For more Injector End Angle information: Open the Holley EFI software & "Help" Contents (top Toolbar), and read the "Injector Phasing Instructions".
