I Have a major cheat!
Go to the sidewinder canyon race, go until you hit the big jump onto the bridge (the one without the gap turn the next corner at the end of the bridge there should be gates; SMASH 'EM! you are on another bridge or something then go straight until you see another bridge to the right. Turn onto the bridge and go straight forward until a message says "you have unlocked the pit" or whatever end the race on the race page you will have torture pit it is FUN! (small though).
