    So right now Livernois is advertising 2 HPFP's for the SHO-one costing $1599 and one costing $2399. The description for both appear to be the same. Maybe someone from Livernois can step up and explain the difference between the two pumps and why one is $800 more than the other. What kind of HP/Torque can one expect using these fuel pumps? Is anyone here on the forum using either one of these hi-pressure fuel pumps? What is your experience? Thanks

    It’s more of a supporting mod, it doesn’t make more horsepower on its own but the stock HPFP can’t support e85 or higher power level where people rely on meth for additional fueling.
    That being said I don’t know what hp levels and/or how much ethanol either support but that would be the difference.

    Someone from Livernois should comment with more specifics

    So I have been on the phone with LMS for awhile about these...

    The 1599 one flows like 30% more and the 2399 one flows quite a bit more. That’s the difference.

    What I have been told is that unless you are running bigger turbos then the 1599 pump isn’t going to net you anything. And they won’t tune for bigger turbos unless you bring it to them for a dyno tune so they can make sure it’s properly setup.

    The bigger pump for 2399 is for guys wanting to run straight E85 with a build motor with bigger turbos.

    Either way, if you not planning on bigger turbos, at this point, they are just insurance policies... no gain.


    Now... I know Rich Y has been doing a lot work with them on the new pump so perhaps some new developments are down the road to benefit those with stock turbos.

    That being said, outside of LMS tunes there have been guys able to run E30 blends with 16+psi of boost on the stockers with perfect rail pressure. Matt at Gearhead is working on a wicked tune using the xdi pump.

    This is a perfect explanation of this, thank you for chiming in and clarifying!
