    ^^^^This....just kidding.

    Looks like it may have been track prep (slow 60' times). I wouldn't worry too much about it, with a little cooler air it will be there for sure....She's flyin.:thumbsup:

      I was a little gassy, but a old guy told me years ago "never trust a fart". It would've been a little awkward to explain the stench back in the pits. LOL

        Ewwwwwwww!!! You got the horrible .00 disease!! I feel your pain! I had the dreaded .000 disease for a couple of WEEKS before I got in the 11’s. I had I think three .000’s before I ran 11.98 which I called DEEP in the 11’s!!!

        it's in at 106°, where Dwayne recommended it.

        The 60', 1/8 ET and mph were off from what it normally runs so I know it has 9's in it.

          You definitely need more fuel pressure. Ive always been set it at 7 and been 5 in the lights.

            That statement is not true. I felt the same way, only i was running 9 psi thinking i would keep more fuel in the bowl.
            I did sever tests to Prove a member on here was DEAD WRONG on less pressure keep the fuel bowl full.

            I set up buckets, valves, measuring devices and proceeded to prove him wrong!!!!!
            What i found out was that at 6 psi i gained a lot more volume then i did at 9 psi.
            Completely backward from what i be leaved!

              Justin i would look for some restrictions in your fuel line before i when with a bigger pump.
              some of them AN Fitting neck down way smaller then you would think.

                  That doesn't work for everyone, I found my buddies car had around 7.5 to feed a tunnel ram, it wouldn't leave clean for nothing. Dropped the pressure to 5.75ish & the next slip showed a missing .350 in et

                    Thumper built my carb and installed .128” bottom feed needles. His instructions were to run 5 1/2 psi. My current pump is a Holley billet 150, I have a Magnafuel 275 that needs resealed. I resealed it once and it leaked again in short order, may give another try.

                    Is that the gerotor holley? Loved my 250 Mallory gerotor, but if it ever needs a replacement, gonna go with the holley. My 250 cost $60, now they are $600.

                    i had a dead headed Holley black on my W5 deal. Everybody said it wasnt enough pump. Swapped in an expensive new fuel system with bypass…. Didn't pick up anything.
                    Your mph is there. Get the 60 foot sorted out, it will run 9.80’s in good air.
                    You jetted up and it picked up, tells me fuel is fine

                      Honestly, I don’t think it’s running out of fuel and don’t see it picking up with a larger pump. That’s why the Magnafuel is still on the shelf.

                          Maga, do you have the black holley pump that is just an upgrade blue, or the gerotor? (which is also black) . Built-in confusion.
