Mechanical vs. electric fuel pump?

Not trying to be mean or anything but there no way that pump pushes that much fuel...it's a 20-30 GPH pump...the Carter super race/street pump with 6 valves only pumps 50-60 with that 1/4 pipe in/out.
The very biggest 6 valve with 3/8's pipe in/out with the huge body is a 90-120 depending on how large the valves are inside...
I've gone through the mechanical pump issue in the past and I'm speaking from experience.

I am using this one on the 410......Carter Mechanical Huge 10an inlet and 8an outlet 172GPH.
No regulator required......will support nitrous without an extra fuel pump!!

Big-time fuel flow for big-time performance.

Carter Competition Series Race Super mechanical fuel pumps deliver big-time fuel flow. Their free-flow output is 172 gph. Despite this high capacity, their compact size means that they often fit where other high performance pumps won't. In addition, they're "clockable," which allows the rotation of the inlet and outlet. They have heat-treated, high-speed levers, plus -10 AN inlets and -8 AN outlets, with fittings included. With 7 to 8.5 psi operating pressure, no regulator is required.
