While tilting the Wii Wheel (assuming that's what you're using- if not, substitute the other controller method), pressing the B button will make either your Kart or Bike leap up into the air. When it come back down, if you keep on moving in a turning motion, the vehicle’s tires will start to slide across the track, perpendicular to the treads. In this way, the kart keeps up its Acceleration, even if it’s curving around a corner.
This apparently causes the kart to gain momentum and heat. smoke starts puffing around the wheels. After traveling in a short arc for a while, blue sparks will shoot out from underneath the vehicle’s engine; a Mini-Turbo is charged up, and releasing the B button will give you a Speed Boost.
Another, even more plentiful bonus of using Manual drift is a Super Mini-Turbo, essentially the same but. well, you know, it’s super! Orange sparks flaring from the bottom of the vehicle designate when this extra-long boost is ready; of course, it will take more work to gain a Super Mini-Turbo. You have to drift around a larger circumference of a corner, about equal to a hairpin turn, to receive a one.
