Hey guys, :welcome:
I just bought a Barry Grant Nitrous Works 2 stage system, 100-425hp it has a 1/2" thick gold plate, it has 32 holes per bar, so 32Nitrous+32Fuel=64 holes.

I bought this system used and the guy gave me a jetting chart that says
Nitrous Jetting Chart

HP Setting Stage 1 N/F Stage 2 N/F
100/200 46/43 49/40
100/250 46/43 67/46
125/325 57/52 85/55
150/375 62/55 93/70
175/425 81/62 120/82

do these seem right?

I have wired the system up so that once I leave the line at wot the micro switch will activate the 1st stage and whenever I hit the push button the 2nd comes on and the 1st drops out, I did this because I only want to run a 100 off the line and 150 tops
so as of right now I have in the 1st stage: 46/43
and in the 2nd stage: 62/55
what do you guys think a good starting point?
or is this chart way out to lunch?
and what fuel pressure with these numbers?:confused:

thanks in advance!! :thumbup:
