Fuel pump limits
Fuel pump limits I have a 6.0 carbed setup with a stinger plate. I have the Holley hp125 fuel pump, flows 110gph @7psi. On motor car runs 11.80 with 100hp shot 11.2 on street tires. When do I need to go with a bigger fuel pump like a 140gph pump?

110 GPH is 440 LPH. A typical Walbro 450 LPH pump has been pushed over 800 HP at the wheels on a turbo setup with a lot more fuel pressure, which is a major factor because it only flows 380 LPH at 60 PSI of fuel pressure.
If the 110 GPH pump is flowing 110 GPH at whatever pressure you're running it at, then you have some SERIOUS headroom.
