Gpm on a single mag?

Looking for a little A-fuel opinion.

How much pump would you guys have to take out if you were limited to a single mag, say to 660'?

I know there is many factors....but here is my current set up.

1975 lb car, 3.42 gear, 1.55 split 2 speed B&J, single 44, AJPE 392 (468 ci.)

I am stepping up my pump, but don't know how big to go. I do not want to by pass a tonne of fuel (but obviously want as much as possible) at the hit through half track....as we will be restricting inlet flow to stay at a sealed pump rule of 11.6 @ 8000

19-22 gpm (NTF) pumps are we're the class guys started....but we are wondering how high we could go?....27-33 lil Bertha?

Thanks!
