fuel system question
what is the factory fuel system good to power wise? I have a few boltons, intake, exhaust, tune, and that's pretty much it, i plan on putting a nitrous kit on the car in the near future and i was wondering what my limitations would be with the stock fuel system shot and hp wise.. I'm going with a direct port kit.

The guys who know first hand will chime in, but just to get you started:

My LS2 was 89% duty cycle at ~400 rwhp. Stock LS2 injectors will go static around 450-475 rwhp if I remember correctly. The stock fuel pump is good to 500, maybe a bit more.
Currently I have 485 rwhp with LS7 injectors at 74% duty cycle and a Walbro 255 lph fuel pump, N/A at 12.5 AFR
