13 t front sprocket

Hey i heard you guys talk about putting a 13 t sprocket. I went to glamis this weekend and smoked everuthing up olds i was really impressed. I have a cherry bomb thats it. not one honda not yama 450 beat me. except 1 highly modified raptor and 2 banshees. suspension is great that were i took all the advantage. will a 13t make me faster? I weight about 180 w/ gear thanks.

I was thinking 1 t out in the rear
