Have you cut the engine and done a plug check before driving back to the pits to check it's not lean or pig rich.I usually take a spare plug and a small wrench, swap it over and check it in the pits. I also had a problem with my motor laying over and it was the carb too close to the scoop. I ran without the hood and it was back where it normally is. Mick

I went 10.24 at 130 mph in my car with a holley blue, 3/8 line and the small holley reg. Great 60 ft though, best i've ever gone is 1.39. Mick

My holley black is not enough on my car. About 520 hp 408 4 speed 3.73 3780 lbs. It quits at about 5700 rpms in forth. Stock type pick up but 1/2" to 1/2" alu line to filter then an8 to reg then two an6.
I suspect your issue isn't the fuel pump. I ran a Holley black on my 422 small block for years( 650 ish horse) 9.80's at 3350 pounds at 7300-7500 every pass. Swapped to a much bigger system and saw nothing, zero difference. At 520 horse a blue should even likely be adequate. Could be filter, pickup, voltage, regulator...... But that pump should be plenty adequate

Forgot to mention i run E85. Filter is on of those inline tubes with a mesh in. Shouldnt restrict much? From filter i have a an8 hose to the regulator witch is the cheap holley modell. After reg i have jegs prebent steel tubing kit. Cant really see the restriction exept maybe regulator.

I would agree with others as the Holley black pump should be more then enough for your setup. I use the Holley black pump also and have the regulator press set at 6 psi. I use 3/8 line and a stock fuel tank with a stock 3/8 sending unit. It feeds my car fine as I have no fuel starve problems at all. I actually had the red pump on before and switched to the black just to be sure it was getting enough fuel but it ran the same 10.70's with the Holley red pump also. Ron

I agree but obviously its not doing good. It should be enough thats why i use it. Maybe i should do a flow test? Also remember that it starts to give up at about 130 mph in a very heavy car. If i run 1/8 it works fine.
If you have a 3700 pound car going 130 mph+...... You are making way more steam than 520 horse
