I have a stock fuel pump, about 5 years old, i wanna know how big of a shot i can run with the stock fuel pump? i got a nitrous works wet kit and goes up to 175 hp..... i got all the bells and whistles too, 36lbs injectors, heads, intake, headers, stroked.....etc

thanks for the help

 

With some of the storys I've read over the years I would just upgrade the pump. Besides your using up quite a bit of the stockers capacity already.
Mine was loud from the factory from day one, had it replaced. 28k later on the dyno (NA) after H/C swap it was going out and couldn't keep up. I have no faith in factory pumps, but maybe it's just me.

 

I also would not run an OEM pump...with what you are spending whats another $250 (Racetronix) for the safety of knowing you have enough fuel supply.
