Less teeth more acceleration, more teeth higher top end.

As people have pointed out for you, a larger pinion (more teeth) will increase top speed; it will also decrease run time and make the motor run hotter. A smaller pinion will do just the opposite on all accounts.

Keep mind, that changing the spur gear size works the opposite as changing the pinion. For example, a smaller spur gear will increase top speed.

On a crawler, increasing the pinion size may or may not increase wheel speed. It will increase top speed, but out on the rock it might hurt more than help. If you want more wheel speed, I suggest switching to a 3S LiPo if you haven't already. Most people who increase voltage and then run low gears (small, small pinion) have the best of both worlds--plenty of torque and all the wheel speed the need when the need it.
