I have an 94 Z28 with 113k miles on it. Major mods are LE1 heads and cam. I think i'm pushing somewhere around 370. My question is, if i were to run nitrous, how big of a shot could i run without running into fueling limitations? I've heard 125-150 thrown around for stock motors, but i dont know about myself. Thanks

 

Each car is going to be a little different. But here is a rough guideline.
Stock fuel pump (4-450rwhp)
Walbro 255 (5-550rwhp)
Walbro 255 w/hot wire (6-650)

The Racetronix kit $249 includes the Walbro and hot wire kit. I would reccomend upgradeing the pump before spraying.
