Noss 

Automotive slang for the use of nitrous oxide as an automotive engine performance enhancer and is usually described in terms of specific power increase to the engine (i.e. 50 additional horsepower from a noss set up would be called a 50-shot of noss). Actual slang is spelled either "noss" or nos and was first popularized by it's use in the film "The Fast and The Furious", where lead character Paul Walker says "I need nos!!" in reference to his car's need for a nitrous oxide performance enhancement.

The term was originally a play off of the name of the company "Nitrous Oxide Systems", whose logo is basically the capital letters N-O-S.

It's use is mainly limited to the import or sport compact side of the automotive performance scene, though in many cirlces the use of this slang is actually looked down upon (where the prefered term is nitrous ).

Dude, my Civic has a 50-shot of noss.
