At a .5 BSFC number, a 1000HP motor needs 500 lb/hr of fuel. A Blue Holley pump free flows 110GPH.........So a little quick math tells us, that with a gallon of fuel weighing roughly 8lbs, that our pump needs to supply 62.5 GPH to deliver the required lb/hr of fuel.........hmmm. Now obviously when you regulate the Holley down, it no longer flows as much, but it is more than enough for 99% of the cars on this board, same for the regulators.

MOST guys problems with their fuel system is NOT the pump, it is the system itself being poorly laid out. Many times the high zoot pump fixes it, because the big pump over comes the issues in the system itself.

We run 900" nitrous pro-mods with 4 and 5 stages of spray with ONE pump. Usually Magna-Fuel 500s. Doubt many 10 second bracket cars need the same amount of pump.........LOL!!!

The fuel you NEED to produce a certain amount of power and the fuel you are actually GETTING, may have little to do with the pump and reg itself.

Before we went EFI, we fed the single Dominator on our 632, that makes just shy of 1200hp with ONE single Holley regulator.......and did I mention it made close to 1200hp on the dyno with that regulator........hmmm...........LOL!!!

Its very simple........If the pump and reg you have will keep the fuel bowls full of fuel for an entire run........you HAVE enough pump.
