Is there a formula to determine how many gallons/per hour/HP a fuel pump flows at a given psi?

I want to calculate if my system flows at least .10 gallons per hour per HP at 6psi.
I have a holley blue that's rated at 110GPH(free flow rate) at 5psi with -8an fuel line.

I think you are trying to solve this wrong

all you do is divide your GPH by your HP to get the number your looking for

so 110 GPH/ 300HP = .3666 gallons/hr/hp

the other problem you are running into is how manufactures rate their pumps

if you assume a few things you can do a relation

110/5psi=x/6psi

solve for x and you get 132GPH, but that assumes the pump is capible of the extra voume, which is a huge assumtion.

is this what your after?

remeber flow rate = area x velocity

assuming laminer flow

Yeah, I think that's what I'm looking for. I just wanted to know if my holley blue is enough for a NOS sniper system set at 125hp.
I'm sure G force is factored in there somewhere.
