Break the sound barrierSent in by Tips, Codes, Hints, Cheats, and Secrets HunterPick a course you know well so you can go without hitting too many walls. It is good too if you have a long strait away. So, pick your vehicle. One with a good top speed and acceleration is good. Start your race and go as fast as you possible can, use your nitros if you want. If you max out the speedometer it will flash red and white. You will hear your sonic boom then it will go quiet till you slow down. Congratulations you have just broken the sound barrier.
