Wow; that is close. It must have been irritating.
^^^^This....just kidding.....................
I think if you would have farted at the finish line you would have got your 9 sec run
I'v been no were near 9, and don't know but here is what i'm thinking.
Some of them AN fitting, can be dam SmALL on the inside diameter. I would look into that before a better fuel pump.
Thought about any aerodynamics.......like maybe a front air damb?????

No failure! Just gained knowledge. Is there room to advance the cam?
On the 10.008 pass I jetted the secondary's down two sizes. The last T&T i ran about two weeks ago I had jetted it up and it slowed a little in the 1/8, just wanted to make sure it wouldn't lean out any in on the back half. The fuel pressure is set at about 5 1/2 psi and is down to 3 psi in the traps.
Not complaining really, the car ran hard but I know there is a 9 in it.
You definitely need more fuel pressure. Ive always been set it at 7 and been 5 in the lights.
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 etYou definitely need more fuel pressure. Ive always been set it at 7 and been 5 in the lights.
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.
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
My buddy runs 350 gph in a stroked small block low tens, I can't remember exactly what he said but I have that black Holley pump he said no you can't use it you'll run out of fuel, pump can't keep up
He's wrong.My buddy runs 350 gph in a stroked small block low tens, I can't remember exactly what he said but I have that black Holley pump he said no you can't use it you'll run out of fuel, pump can't keep up
Okay, that's possible.He's wrong.
My opinion only.
Thanks, saves me from buying another pump lol.i went 9.80 at 3350 with that black pump. Its plenty of pump. 1.34 60 foot
guys running them on 8 sec cars making 800+ horsepower
Maga, do you have the black holley pump that is just an upgrade blue, or the gerotor? (which is also black) . Built-in confusion.
