Hint: Subtract time from total amount:
When running low on time press A to do a popper wheelie and hit another car and do a "Super Flip", which will earn one bonus second. You can also do this while turning (your car will just tilt to one side, sideswipe another car, and you will do a barrel roll and get two bonus points). If you do these while hitting a ramp you will also do the tricks. The game will subtract the amount you earned from the total time you have been racing after the race.
