Is my FUEL pump enough???

I have an '84 coupe with a modified 350 TPI that is pushing around 400 HP. I was in a bind the other day and had to put in a stock replacement fuel pump. My question is....how much should my pump flow for that kind of horsepower. Also it has 30 lb injectors installed, are they enough or do I have to go bigger?

Thanks

The stock fuel pump is good up to "about" 400 HP. You are on the edge. As long as you are not racing or hitting WOT you will be okay. I would look toward replacing it with a better unit.

The stock '84 fuel pump is designed to meet the spec for 9 to 13 psi fuel pressure. It does a good job and will exceed all stock needs, but I can't imagine it will provide the 40+ psi pressure the TPI needs for very long, if ever. To know for sure, test it.

RACE ON!!!
