I agree with Mike that until maybe a year ago, Nitrous Oxide Systems was the only system anyone here would use. Then again, they were based out of Cypress until Holley bought them, so I guess they were pretty local.
I have always called it either nitrous or juice. My best friend Dave was the first person I ever heard call it NOS (NAAS), but I soon realized that a lot of people around here do. I thought it was funny, because when I lived in L.A., a mere 45 miles away, I NEVER heard anyone call in NOS (NAAS). I just figured it must be a Ventura County thing. LOL. Below is a pic of Dave with my new bottle in '94. FWIW, he's now married with child, and shaved most of his hair off. I guess one of us had to grow up. LOL.
Take care,

P.S. Mike, recognize the banner behind him?
