4:11's, 4000 stall vert and nitrous usually do not mix. especially on a 26" tire.
I ran N/A for years with the 4:11's and a 4000 stall vert but that was on a 28" tire.
Depends on your power level too.

What do you run on motor low 11's @ 124? You could spray 150 on top of that as long as you buzz 6800-7000 I would think thru the traps.

Default same set up, just 30" tire
I have a 4.11 gear, 4000 stall, and 150 shot on a 30" tire and it traps around 6300-6400 if I'm not mistaken.
