  • Question

    Hell i have a 65 Volkswagen bug with a Carter 500cfm 2br carb conversion on it. I would love to be able bolt on your product. Is there a way too program the hardware to be compatible.

    By Ian P. on March 9, 2018

    Answer
    Ian, We have tested the 2300 2bbl Sniper EFI system down to roughly 95HP with success. If you could adapt your throttle body flange to a Holley 2300 Flange, I believe you could successfully install our EFI system.

  • Question

    Can this system handle a low amount of boost via a paxton style supercharger. It will be going on a Ford 170CI motor that puts out 95HP I would like to know if this can handle maybe some BOOST

    By Sal M. on April 17, 2018

    Answer
    Yes, there is a 2bar MAP Sensor built-in to this unit.

  • Question

    Will this work on 4 cylinder applications? I have a 2.0L Ford Pinto Engine that has been modified with forged pistons, Crane Cam, Mallory ignition, etc. It is currently using a 4160 390CFM carb on a Offenhauser Manifold.

    By Dave S. on March 3, 2020

    Answer
    If the carb is currently doing an adequate job, the Sniper throttle body should do it better!
