Default 1 pump or 2?

I have read most of the treads in here and cannot find an answer.

My question is what is the limit of horsepower you can get away with on one walbro pump? I see the sticky on how to install but nobody really has anything on when you should go to dual intank.

I'm in the process of building a 440 cu/in n/a motor, it should be flirting with about 700 flywheel HP. I have an NX wet kit on the car probably going with a 200 shot if I use it . Now I realize that if I spray the motor I will need the second pump, but will the single pump keep up on motor alone ? I should also note the car had a 408 in it making 530 rwhp.

About 550rwhp is all I recommend for 1 pump. You are above this level on motor.

I have dual pump kits if interested in a reliable turn key setup, plus I can design a fuel system to support the power level the car is capable of.

A nitrous setup can be demanding on the rest of the system.

If I can help, let me know.
