Safe amount of nitrous. And help ?

[84gt347]

i know you can run a 100 shot and probably a 250 shot with proper timing and fuel. Here in lubbock, that would be good for mid 12's. I have heard people say 11's, but i havent seen it yet. There were a couple of guys that played with a 250 shot and netted mid 11's. There motor did not have the mod list you have though. I am trying to figure out a safe way to run a 200 shot with full timing using higher octane fuel instead of reducing timing. if you hear of anything let me know
