Depending on the gear, it can move the useable hp to better rpm range for the track.
It typically give you better off the line kick, but too much gear can make the car "use" up all of the power before it gets to the end of the track.
I have always been taught that you want to shift right into forth(or the 1:1 gear) before the end of the track. This is a guide and not an absolute and it all depends on where your hp's powerband falls rpm wise.
