There are 3 types of speed boosts. 1: Speed boosts that were built for the track. 2: Mushrooms from item boxes 3: Drifting speed boost The drifting speed boost is a little tricky. It's very useful when going around sharp turns. First when going aroun the turn, hold R. Then while still holding R, quickly alternate between left and right. You should see blue sparks and then red sparks. When you see red sparks let go of R and you should get a short burst of speed. This does not make the blooper ink go away from your screen should you get inked.

First of all you must have your kart/bike set to Manual mode (Don't worry! It's not manual gears!). Now approach a corner, turn in and hold B. Keep holding B and flames will shoot out the back of your kart/bike. Let go and you will get a burst of speed. The flames differ on kart or bike. If you are in a kart the flames will go blue and then orange (which give you more speed). In a bike however the flames will only be blue (the bike ability is the wheelie).
