That was at the Pump Gas Drags. Yes, he used that because he was spraying and running pump gas. At DW we put race fuel in but he still only had the 2 old holley blues in his car

could one old holley blue pump support 550hp with a return style regulator ?
sorry if this is a jack, but it does pertain to return style regulators. [i think]

Yes I did it, tank was in the front of car pushing back, 800 hp. Learned this from two guys running dragsters, running 600+ cu in chevys. That old test of how fast a fuel pump can fill a gallon can relates for rear tanks (overcoming g forces and selling high dollar fuel pumps). (Gas is heavy) where does all the junk in your car go when you nail it?

... 'cuz I'd like to hear more about what size (GPH?) pump people think is necessary to set up an effective street/strip fuel system having a bypass/return deal and supporting maybe 700 HP. Thanks - Brad

The 255LPH pump I used was BARELY good for 600 HP @ 6psi ,,the 400 LPH would work for 700 hp. this is an intank EFI pump I was using at 6psi on a carb & return, & as I learned from Dwayne, you have to do a Volume test @ the pressure that is going to be set at. going through the fuel line & filter that is on the car.

I'm really not sure what GPH the Aeromotive A1000 pump flows, but I'm sold on it. It's "rated" to feed 1500 hp NA on gas. It's one of the more popular pumps on fast street driven cars. Been running mine since 2011 I think and it's been flawless.

I did fuel flow tests on my old pump gas Duster due to not being able to jet it up rich enough to slow down the MPH in the 1/4 mile. I had a Magnafuel 275 (suppose to feed 750HP)pump on the car and bought their 300 pump that was rated at 900 HP, my moto had a six pack set up on it so I flowed the pumps with all three flex lines into a five gallon plastic fuel jug for 10 seconds three times on the 275 pump first and then the 300 pump after swapping them out, no noticeable differences in the flow
I call Magnafuel the next morning and told them what I had tested and they told me that I needed to either do the tests with the fuel bowls attached to the lines or put a restrictor in the lines to load the pumps, don't test unrestricted. I decided to hook one line back to a carb and redid the flow test three time, it gain over 40 % flow increase through two lines on those three tests
I ended up finding out that the 10 micron fuel filter I had mounted between my gas tank and the fuel pumps was restricting the fuel flow into the pumps
I ended up putting the 275 pump back on the car and it worked fine plumb like Magnafuel said to plumb it
Sometimes we need help on figuring things out, huh
