14t and 15t front will give you more top speed than the stock 13. It works out to be about 5mph per tooth.

On the raptor though, if you have more high-rpm power you will have more top speed because it doesnt rev out all the way to begin with. Stock rev limit is 9000rpm at about 91-92mph and stock it wil only turn out about 75mph at 72-7300rpm.
