Do stunts to earn money and build up your turbo bar, when the turbo bar is full your car will gain a turbo boost. There are 10 levels of turbo boost.
The longer you can hold each stunt, the more turbo and money you will receive. Doing more than one type of stunt while in mid-air will gain you combos. Combos will give you much more turbo and money than single stunts.

BACK WHEELIE: Drive your car on its back wheel for more than one second, hold A or LEFT ARROW key while accelerating or reversing.
FRONT WHEELIE: Drive your car on its front wheel for more than one second, hold D or RIGHT ARROW key while accelerating or reversing.

PERFECT LANDING: As your car lands, make both the wheels touch the floor at the same time.
