can ne1 explain a fuel pump ? for me???? 1. I have a weldon 600A that flows supposedly 70 gph at 40psi. I would like to know what hp level is safe to support with that kind of pump (I've heard Nate from Nasty say 800hp but all the stuff on the net says 600 for fuel injection and 700 for carb)..... So i'm wondering how much power I can make with that pump before worrying about blowing my motor. (I'm currently making around 750hp at the flywheel on spray) OOOPS....
2. The Aeromotive eliminator i'm looking at flow 650 lbs/hr at 45psi..... So how much more fuel is that than 70 GALLONS per hour????? I basically want a pump that will flow ALOT more fuel than the 600A so I don't have to do this again in a year....
3. Specs on the eliminator say 1200hp forced induction and 900hp Naturally aspirated.... Why the 300 hp disparity???? Seems to me like it'll provide X amount of fuel no matter what it's going into.... i don't get it. And what is a nitrous car considered? IT's neither forced induction nor natural aspiration... but extra fuel IS required for the nitrous usage....
My setup is a single stage wet plate on a 383 LT1 currently jetted for 150 hp but considering upping to a 300 shot once the bigger pump is in place... 10AN feed and 6An return. 96lb/hr injectors. FAST XFI.... sumped tank from nasty performance.....

Sure it isnt 1200 n/a, and 900 EFI ?? ( electronic fuel injection )
As you increase the fuel pressure, the flow from the pump drops....
So for a carb setup that might only require 100 gallons per hour at 5psi, try that same pump at 50psi, and it might only flow 80 gallons per hour ( just plucking numbers from thin air as examples )
So generally once you up the pressure, HP ability is reduced.

here it is from Summit directly...
I don't understand the 300hp difference.... and what is a nitrous motor considered?????
Designed for serious EFI engines making up to 1,200 hp with forced induction or 900 hp naturally aspirated, these Eliminator fuel pumps deliver more than 650 lbs./hr. of fuel at 13.5 V and 45 psi! Features include a patent-pending "dual-chamber" pumping mechanism, -12 AN inlet ports, -10 AN outlet ports, 6061-T651 aircraft aluminum alloy housings, and a great looking, bright dip red anodized coating

what's even worse is that Jegs description of the pump is completely different. says it will support like 1600 hp on an EFI engine.....
WTF?????
I'm gonna make some phone calls to my tuner on monday and go with what he feels will support the fuel requirements....
