So if your a performance guy
you can change your gears on top or bottom to change your gear Ratio to be quicker on the line or faster top end.  Do your math on your gear ratio by: Dividing the small number of teeth into the larger number of teeth and that number is your gear ratio.
With that said,

Definition: Gear Ratio,
The ratio of the speed of rotation of the powered gear of a gear train to that of the final or driven gear.
Gear Ratio’s can be difficult to understand, but with a fairly brief explanation I will attempt to make this often misunderstood equation VERY easy to grasp. Simply stated, a gear ratio is a numerical value that describes the relationship between two gears (a spur and pinion gear for our discussion). A gear ratio can also describe the relationship between the FIRST gear and the LAST gear in a gear train (or a transmission). You take the number of teeth on the DRIVEN (Spur) gear and divide it by the number of teeth on the DRIVE (Pinion) gear………the numbers are expressed as such: A 72 Tooth Spur divided by a 20 Tooth Pinion = 3.60 to 1 or 3.60:1
