The general rule of thumb is 2 degrees per 50 shot. Do you have a stock motor? I ran nitrous for 2 years and ran 12 degrees on 91 with my NX 100 shot and gained a consistent 11 mph with it. You're better off starting with a little less and work up. I'd start at 10 and go from there.

this will work most of the time, i have seen 12 base with a a9l and a 100 shot of NX on a 10:1 306 with stock e7's, all with 91 pump
and have also seen a similar combo with less compression detonate on 10 base with a a9l, same nx 100 shot
i guess what im saying is start at 8*, and work your way up one degree at a time until it detonates, then take 2 degree's out to keep it safe
what heads do you have, what the combo, that will make a small diference

just my .02 cents i was squeezing a 175 shot on my stock block with the timing at at 6 and i was running really good. i ran a 12.8 at the track i could have done better but it was like 100 degrees.

what was ur 60 time with that 12.8? you should be at least mid 12's or lower with those 4.10's.
