    As above, totally depends on power and fuel.  Built mine to supply constant 1,000hp of E85.  Currently only making 650ish but wanted to do it once.  I am running a Weldon DB2015 main fuel pump, duel Pierburg lift pumps, have a custom Bain Racing drop tank, with integrated internal 3L (nothing in boot) 5/8″ supply, 1/2″ return lines.

    Not sure about a custom surge above the diff, I had a good look at that and couldn’t see a place to fit it and still work properly (IRS though).  It would end up being long and flat which is sort of opposite what you want.  My engineer wasn’t thrilled about the idea either but that may not be an issue.  I reckon the single one piece custom fuel tank is the perfect solution but of course costs about $1500.

    A single Intake walbro will meet your needs.

    However

    If surge is the go. Stock in tank pump to surge. Single 044 to rails, factory Bosch reg. Return to surge. Surge overflow to main tank.  All stock fuel lines. Done.

    400rwhp, is about 530ish fwHP through a stalled auto  That’s getting up there, personally I wouldn’t run a car making that without the peace of mind of a surge.

    Surge is only there to stop fuel surge.

    Nothing power related

     

    walbro do a 430lph version of the gss342

    But fuel starvation matters a crap load more if you are pulling 7k @ 530hp, and odds on you are going to be up in the region where the in tank swirl pot isn’t gonna cut the mustard.  Always surprises me how someone may spend $20+k on an engine but won’t spend a few hundred more on a fuel system to match.

    Dont run the tank below 1/4 and you will be right. But it’s one of those things where it comes down to personal preference.

    Fair call, I just wouldn’t do it.  Leaning it out is something you really dont want to be doing, but yep more than one way to skin a cat :yes:

    Just get a aftermarket industries serge tank

     

    iv got a sp1200 with 2 walbro 460 pumps and I carnt explane how good it is, puts all competition to shame

     

    iv had several fuel systems, and all but 1 have all had one major thing in common

     

    they are hideously loud

     

    my current sp1200 fuel system is near silent, I know my fuel pumps have primed because I can hear it squishing through the regulator  :yahoo:

    ^ beautiful workmanship, that pump will actually flow around 1,500hp, nothing like a bit of overkill though :)

    No it wont, thats what julian explained the other day, what the holleys advertise and what they actually can do in terms of big numbers like that are completely different, I wouldnt even trust that pump with 1000hp on an EFI blown setup. Carby is different, but when we spoke on the other day on the phone he was explaining fuel consumption, psi, fuel line sizes etc These pumps are rated to flow 200gph but its more like half of that for my kind of setup. He has all the data to back up his claims so i will back him 100%
