Starting Boost
When the countdown starts wait until the 2 has almost disappeared and then press and hold the 2 button. This will give you a quick boost at the start of the race.
Boost after falling
When you fall into something, such as a pit, if you hit 2 the moment you're placed back on the ground, you get a temporary boost.
