Can a 190 lph fuel pump safely support 400 hp

I e recently upgraded my allen supercharged bird with the following mods 2001 PI romeo engine, magnaport supercharger, ported inlet, 75 mm throttlebody, custom made 3 1/2 inlet tube, Kooks mid legenth headers, and 38# hr injectors. I anticipate that I will make around 340-350 rwhp and 400-425 rwtqe. Will the 190 lph fuel pump be enough or should I upgrade to a 255 lph fuel pump.

Do a search on fuel pumps and also you can read what the big dogs run in members section by looking at their profiles.

Most have the 255 pump and a few have the forced induction pumps.

I am not a expert by any means. I only wish my car would make close to the horsepower than you are and I am running the high pressure 255 pump and 42lb injectors.

I believe having extra capacity is a good thing.

Yes

Not on a supercharged engine. I would upgrade to a 255 lph FI pump. I've seen too many broken engines because of going lean.

The standard 190 lph pump doesn't flow enough with over 10 lbs of boost (50 psi fuel pressure) for that kind of horse power.
