Hints & Cheat Codes
Turbo Muffler Explosion:
Race any course with a car that you can install a turbo (try the Evo). Try to get up to top speed, or as close as possible and then release the gas or hit the brakes, and an EXPLOSION will come out of the muffler.
Unlock Tamiya Kagegawa Circuit:
Finish the Final level (seven races without the mountain passes). There is a Strict Remote Controlled car challenge.
Note: Your car will not be as fast as it would on an ordinary track.
