Well im no nitrous expert but im a nitrous user, but i know that i was told to never use under 92 octane. But i know alot of people live in Cali are on here. They may help you with locating places with 92 octane.

I, my self, would not put in 91 octane. I mix it up with racing fuel when i use the nitrous just to be extra safe, and cause i love the smell of the leaded fuel burning!:)

I'm no expret on NOS but If you just go and
buy a octane booster for each tank you
should be ok. There are a few good cheap
brands out there that add like 6 pts.
of octane. Just my 2 cents. :vpleased:

i noticed everybody says 92+ octane should be used, but can 1 point lower (91) cause detonation?
i been using 91 octane so far. nothings been going wrong but as long as u dont use lower then 91 then it should be fine.

you shouldn't hve any prob's with 91 octane. that's also the highest we have here in tucson. just retard your timing 2 degrees and you'll be fine. i run 91 on the street with 100shot and 12 degrees timing and stock timing with 107 octane (UNLEADED) at the track. good luck
