I was reading a new magizine (Car craft) i got a few weeks ago and came across a Fuel pump comparison test for high horsepower engines. All pumps were run at 13.2 to 13.5 volts. I thought i would share it with all of you, i see some on here are running twin pumps and never realy heard of any other pumps beside the Aeromotive. Here are some options and facts.

Pump LB/HR @50 PSI LB/HR @60psi

Walbro 255 340 315
Weldon A600-A 403 384
Camaro LS3 419 380
Bosch 044 450 436
Aeromotive 340 462 428
Cadillac CTS-V 719 670
Aeromotive A1000 780 750

The Cadillac pump contains two turbine pumps running continuously.
