I have found a lot of threads on how much the bottom end can handle with nitrous, but how about the stock fuel system? From the search I've done, I noticed a 125 dry shot is fine with everything else otherwise stock, but figured it wouldn't hurt to ask. Also can you squeeze out more if you did it in 2 stage's, or is 125 hp more as much as the stock pump and/or injectors can take?

 

Dry your pushing it as it relies on the injectors flowing enough fuel, which they unfortunately dont. 98, 01-02 have 28lbs, 99-00 have 26lbs.
Wet, yes you can get away with 175 nearly stock setup as you mention, maybe more.
Replace the fuel pump and go bigger shots for wet, or pump and inj. and do it dry.

 

So with a dry setup what injectors would be good if you were going to spray under a 150 shot. Probably 125 max, more like a 100 for me. I have FMS 30#ers right now, and a walbro pump. Would that be fine for my 125 dry? I am looking to get into nitrous real soon. Just setting my car up for it. Trying to locate a 12 bolt and some tires.

EDIT: Also, I should mention my car is a H/C car. 231/237 0.595/0.595 cam.

 

I'm staying with 100 shot (til I get drivetrain and fuel pump installed)

but I drive an LS2 GTO
