Fuel demand

615 HP @ full throttle for 15 seconds ?
On the street ?
Can anyone calculate the terminal speed ?
I ran just over 500 hp with a 440-6 in a 4000 lb charger with 3/8 and a carter HP mechanical pump ( pretty much stock setup) with no issues. Adding an electric pump should be adequet I would think.


Explain how horsepower is the determining factor in pump selection please.
