What year car? I've read that they are as follows for f-bodies:

1998: 28.6 lb/hr
1999-2000: 26.4 lb/hr
2001-2002: 28.8 lb/hr

Whatever it is, you will be fine with a healthy working stock fuel system as long and you're not way over 400 rwhp.

I'm no expert on this stuff, but my understanding is that once you're approaching 450 rwhp a fuel system upgrade is wise; a single Racetronix pump upgrade and some larger injectors. 42 lb/hr? Maybe give a call to one of the many vendors for some solid advice.

Sorry to bring the post up from the dead .. Can someone link the Stock part numbers for the injectors??

98,01 up 0280158931
99, 2000 0280155890
to clarify the size, since most aftermarket injectors are rated at 43.5psi the sizes are as follows
98,01-up are 24lb injectors
99 and 2000 are 22.

they flow 28.8 in the 98, 2001-up because of the fuel pressure of 58psi.
they flow 26 in the 99-2000, "

Ok so If came across a set of 25 lb injector they will flow at 29 or so because of fuel pressure being 58 psi??

Reason I ask I'm doing a 100 wet shot.

Want to make sure I get enough fuel.

With a wet kit the fuel injector does not come into to play as the needed fuel for n20 is metered separately

You'd have to find out what delivery pressure the injectors were tested at when they measured 25 lb/hr.
