    just talked to the shop who is doing my build and it seems that at 21lbs of boost an over 9xxwhp you run short with the stock fuel pump...

    Currently running a KB boost a pump

    Does anybody make one yet ?

    Build info and final numbers coming soon but looking to see if I need to scale it back or if I have options....

    Thanks for any info !

    The Hellcats have a built in boost a pump type system, in going E85 your going to need 30% more fuel, I would ask Tammy to ask Doc what he used..

    There are plenty of upgraded aftermarket fuel pumps out there. Look at turbo Mustangs, Supras, GTR's, etc., over 1000whp and imitate their fuel setup. You may need to go to a return style fuel system, Magna-fuel makes a great billet fuel pressure regulator. May take many feet of braided stainless steel hose and -AN fittings.

    I've got about $5,000 worth of -AN fittings sitting on my dining room table right now...fuel coolers, all kinds of goodies. If you are circulating lots of fuel in a return style system, it will build up heat, so put in a fuel cooler, like a tranny cooler, but for fuel.

    Mowe, we just built a new setup for the shop car. We are going to install an upper to go along with the already installed lower and try to get it on the dyno this week.

    I will share more after testing with the 2.5 upper. I'm not holding out, just want to make sure everything works like we think it should.

    Looks like our solution works. We put down 907/879 on 18psi, hot as hell and having belt issues. Now it's time to get this thing in to production
