Will it hold if I have to run with the stock pump?

Well it's well known on the corvetteforum.com that the stock walbro pump will easly support 550hp and many guys go as far as 600plus, can check it out in the forced induction/n2o section, many, many posts on this ( and experiance). As far as the f-body, I just go by what the guys have been reporting on this site for some time (that's why I said about, not totally sure).

i was spraying 150rwhp tnt wet kit shot which is the hardest hitting shot of its kind imo.. on the stock fuel system right down to the pump trapping 122.8 with lid cutout and nittos on a otherwise stock car..
i dont know how i would hoook up a progressive thing or where to find them.. only ones i see in jegs look for oldschool motors ect.. can someone fill be in on this.. im upgrading a 255 pumpa nd thats it.. i dont really see why u upgrade injectors for a wet kit???

Anyone have the part # for the stock vette and f body pumps you should be able to cross reference them and see the flow difference, personally I dont care, swap it out and spray away.
I have run the NXL jetted at 220 stock bottom and cam only. No issues other than a clogged filter.

Are you saying you have 185 jet pattern or you have it jetted to 200 (Sig) and it puts out 185 on the rollers? Always thought posting gains instead of jetting was

I try to keep the bottle over 1000-1100. With the 150, I am running 28 degrees of time on 114 race gas. -- the gas prevents detonation not more hp.

Is the 114 in the tank, or do you have a standalone system?

If I was thinking I would have pointed out that it was pointless for people to say they are sparying XXX wet kit on stock fuel system, because the stock fuel system doesn't have to supply the extra fuel.

First question:
Magic chicken quotes part of above question and asks:
I answer with:
That whole line is referring to injectors. I realize that it doesn't mean anything for wet kits, hopefully others do too, but apparently they don't.

*MENTAL NOTE* blkZ28spt and I are referring to Dedicated Wet Kits(stand alone fuel cell), where as the fuel pump is only providing the NA HP. On traditional wet kits, the fuel pump is a major NEED item. The stock fuel pump, although proven to go beyond 450rwhp, is not recommended as when the activation occurs, it draws a large amount of fuel from the STOCK rails (or aftermarket), and the design of the STOCK system causes a lean condition on the drivers side, where the wet kit taps off the STOCK rail. But agree'd most ppl should already have that part down, but most tend to skip the stickies at top, the Colonels Nitrous Tech Files and that invaluable Search button.

Stickies and the search button have SO much information to offer.
Good explanation there.
