RWHP limits of stock fuel pump?

Thinking of going to the granatelli intake fuel pump.

Its in summit for $125.

Im soon to be making 430rwhp+ so i know im reaching its limits. Especially at 200K miles on the pump.

You can get the walbro for 99 bucks and its high pressure 225 lph.

As for stock limits, ? Mine bit the dust as soon as i put the cam in my car. Dont know if that was a coincidence or i just didnt notice it with stock cam.

I made over 400rwhp & fuel pump pressure doens't even blink, just wire the fuel pump to operate off a relay like the racetronix fuel pump harness does & you'll support over 450rwhp easy I bet.
