OK, I have had a 100 shot NX/NOS custom nitrous setup on my daily driver for about a month. I think I am ready for some more juice

What I need to know is the following:

1) Can I run a 125 or 150 shot with no repercussions on California 92 octane pump gas, or would I be forced to hunt down race fuel for the rest of my life?

2) To run a 150 shot, would I have to go with dual nozzles? As in one on each side of the bellow, or is the single nozzle setup that I have on one side of the boot sufficient AND efficient enough.

3) Is it exponentially harder or more dangerous to the motor to run a 150 over a 100 shot?

and last but not least....

4) I am running a stock "accordion" bellow right now. Is it better or worse to run a smooth bellow vs. the stock ribbed piece?

Thanks in advance...
