In any race with a countdown, keep the pointer of the tachometer between 4 and 5 to get a good start and a little turbo boost. If you keep it between 5 and 6, you will get a super start and a great turbo boost. Be careful; if the pointer is in the red (7 and 8), you will get an over rev and be stopped for a few seconds while your opponents drive away.
