Thread: Running out of fuel?

  1. #1

    Default Running out of fuel?

    Just did a datalog with a short full throttle pull and it appears that I either don't have enough injector, or fuel pump. I just want to confirm this. I'm using the Terminator (550-406 four 80 lb/hr injectors). As seen in the graph, my AFR goes lean to 15.1, and fuel flow is 344 lb/hr.

    What's the engine combination? Andrew

    It's a 383 SBC with a Roots blower running 3 psi of boost. I'm estimating around 500 HP.

    It's possible you're running out of pump, but that's a lot of fuel, assuming it's correct. Is everything correct in the System ICF? Andrew

    Yeah, check your "Fuel System" & "Fuel Injector Information" in Engine Parameters.
    May God's grace bless you in the Lord Jesus Christ.
