At the end of the game or just before. When you verse Kenji, Angie and Wolf in the canyon you get $50,000 for winning. So after you get the fify thousand all you have to do is choose continue (you will keep the money), then lose the next race and choose continue. That will take you back into the canyon, and if you win that you will get another $50,000, along with the $50,000 you won before. So from two races you end up with a total of $100,000. Good Luck!
