In Episode 7, Scenes 1, 2, and 3, you can go ahead of younger Black Jack, but not too far. You can beat him to where he needs to go (listen to Luke for when you need to turn).
Extra power-ups
Collect a power-up, then leave that location and return. The power-up will reappear and may be collected again. Note: The maximum number of nitros that may be collected is five.
Fairgrounds shortcut
There is a shortcut in the fairgrounds on any two player mode. The shortcut is located towards the end of the lap. As soon as you start seeing the audience, there is a small road on the right with a road block. You can zigzag through the road block and use the ramps to jump over more of the road blocks along the shortcut. It leads to the start/finish line. The shortcut can also be used while racing the other cars.
Fastest car
The fastest car is the "Ace of Spades". It can be unlocked by completing the game under any difficulty setting.
Hidden fairgrounds nitro
A hidden nitro may be found at the fairgrounds on any mode. Get to the point with two jumps and an orange fence. A nitro power-up can be seen on the other side of the fence. Drive through the orange fence to collect it.
Keep Luke hanging out of the window
When Luke is hanging out of the window, you will need to go drive slower, or he will go back inside the car. Likewise, if you hit anything hewill go back inside.
Losing the police
When chased by the police, you can cut them off by hitting them on the back when they try to cut you off.
