Using a bigger sprocket in the front is like having a smaller sprocket in the back. the smaller the rear sprocket the faster the top speed. I am not sure about racing I know in a bunch of the classes they wont let you change the front sprocket size from an 11t

Harry's right. Most people leave the front sprocket alone and just change the driven sprocket to change the ratio between the top end and hole-shot. A larger driven sprocket give you fast from the starting line but low top-end speed. A smaller driven sprocket gives you a slower start from the line but gives you a faster top-end...to a point.
Some of our customers state that when they can't quite dial their sled in by just changing the driven sprocket that by going up one or two teeth on the drive sprocket it gives them more adjustment. Theoritically it shouldn't make a difference when you calculate the gear ratio to be the same, but some swear it makes a difference. For me the jury is still out.
