Fuel pump question

I was just wondering, how much HP can you run with a stock fuel pump before you need to upgrade. I am building a motor in the 450hp range.

Re: Fuel pump question

250HP is the ceiling figure I've seen for a stock TPI pump. Kinda takes the mystery out of why they croak off so much, huh?
