Accelerate immediately before the “1” fades during the pre-race countdown to start with a slight boost in speed.
Drive on the wrong side of the road to keep increasing your boost. This can also be done by driving in the center of a double lane. Drive on the wrong side of the road and use the turbo when you get it. After it is gone, your turbo will either be full or half full.
Drive a perfect lap (a lap without any accidents) and your bonus will be automatically filled.
