To add to u r gas when u race and how much with how much gas? Thanks last time i used that NOS off road stuff it worked goood on a quater tank of gas

go buy a gallon or two of c16 and it will be cheaper and better and last longer than any stupid octane booster out there except xylene. add it to a 1/4 tank and your good to go.

errum, I really doubt you felt a diff. Prolly just the ol placebo "I put this in and it ade me faster". In reality, it only bumped you up about .5 of an octane point.

Theres a recipe for racegas on here...search.
