    Will probably get a few different ideas and opinions on this, so i'd like to hear the broad spectrum of ideas on the topic.

    We run a Enderle 110 on the hemi in my altered (426ci, 14-71 standard helix, msd 44) and beginning to think the pump is not quite what it used to be. The class rules state that a 25 gallon pump is the ceiling limit on flow with no overdrive on the pump. Would it be worth putting such a large pump on a small motor? Or because the motor has the big 44 on board it doesn't matter what we throw at it, it'll burn it.

    And with that said, who would be good to go to for help with fuel system tune ups? I take it fuel tuneups are tailored made for different applications and combinations when you purchase fuel pumps etc?

    Thanks
    Joe

    (Apologies if at times the post sounds crude, fuel systems isn't one of my stronger points when it comes to engines :()

    It is absolutly the best to have a oversized Pump for a combo,
    and then resize it with a pumpsizer/pump loop.

    There are 3-4 well advertised people who flow complete fuel systems,
    and also give base line tune ups for your specific combo and needs.
    WHO YOU CHOOSE will all depend on how far you want to ship your system,
    and how much it costs to have the system configured and then flowed.
    All of these guys know what they are doing, and how to do it right,
    you cannot go wrong by using a reputable fuel sytem guy.

    Spud Miller,@.F.I.E. This is who I use,..for my fuel systems
    Ralph Gorr
    Randy Anderson
    Gene Adams

    There are others to add to this list so if anybody else wants to post the other two big names
    I am failling to remember at this moment please feel free to add them to this list.

    Hi Vic:

    I will get in touch with a few of these and see what I can find suitable for us.

    Thanks!

    You are more than welcome to borrow my Lil Bertha if it would help. After all, I won't be using it for a while :) It's supposed to flow 18.7 gpm.

    Also, Dave Wilson has flowed pumps for me before.....

    Cool ,..do it right the first time.
    Just remeber to have evrything flowed, not just the pump.
    A good fuel systems guy will flow everything, jets will get flowed individually to make sure they are of correct oriface and or will be marked appropriately to what size they actually are. When these guys flow a system it means the entire system,.from the pump, pump loop/ pump sizer, barrel valve, nozzle lines , nozzles, distribution block, by pass/2nd bypass, main, high speed lean out, and what ever else your system may contain.
    The data that is collected when they flow the system or individule componets
    is logged and recorded to show before and after results, and then entire systems configured to your motor combination, car weight, tire size, tranny, etc,..is used to determine how much demand for fuel will be needed, and then flowed in certain corrected factures, alt/baro/temp, corrected altitude
    etc,..to give you your baseline tune ups.
    As for the cost my Hillborn stack injected system, enderle 110,.etc..to flow with three baseline tune ups, inspect /recondition pump, pump pressure profile, clean nozzles, flow nozzles, refurbish barrel valve,
    input data logs etc,..was $600.00
    This was all done at Fuel Injection Enterprises with Sud Miller, excellent guy
    to work with and ask questions very indepth detailed work and finished product. Spud also does Magnetos,.
    Spud took my 1.2 amp Vertex mag, wizbanged it, and is now 5.2 amps and after 1.5 yrs still works excellent,...GREAT STUFF....

    Good luck with whom ever you choose,..

    Hi guys.

    For this coming meeting i've very kindly been given a Waterman pump as a loaner to check our fuelling issues. This pump truly is a work of art, and should give my car the kick up the arse it desperately needs.

    Now i'm going from a 13gpm Enderle 110 to a Waterman (16gpm at 4000rpm) pump, and looking at my fuel system, would anyone recommend changing pills or jet sizes? I don't want to put the setup we use on a public forum, but if anyone here has used big pumps on a 426 (or similar size) hemi then i'd like to know your input.

    Thanks to everyone who have helped me so far. :)

    Dude,......
    you want a magical answer and numbers without revealing your
    info,..lets just say there can be suggestions to add a pump sizer to reduce it
    to say 14.2 gallons or even 14.6 gals,..
    what were your plugs looking like with the 110 pump,..what will your nozzles flow with this 16 gallon pump,..you wont know unless its flowed,..you will chase and play test n tune until you are someone else figures it out for you, but dont give any info on your set up that really helps.
    look at it this way,..nhra top alcohol funnies run a 18 gpm pump, and run a .100/ or .110, or, .120 pump sizer to give around 14-15 gpms, but yet their
    motors only see around 12.3 to 13.6 gals to the actuall motor in a run,...
    Nitro injected motors / A/fuel they run a 38, 44, 52 gallon pump,.how much do you think the motor actually needs or wants.

    You ask publicaly for help, but the important or less important info is with held,
    I dont think anybody over here is to concerned with competing with you long distance,..so whats the difference in asking for pertnant info, when you wont get your whole system flowed.
    heres my two cents,.....if you leave it as it is with the 16 gal pump, you will have alot of pressure, great atomization and a whole lotta fuel going to the motor causing it to blubber,and be down on power,..I am thinking, and Mike or Dave feel free to jump in , but I would put a .050 or .060 sizer on the pump and go from there, make adjustments at the barrel valve for idle egts etc,..and go run it,..and this is not knowing anything about your set up.

    that`ll be ,...$250.00...just kidding..:p

    Good luck


    ;)
