here was my sons thinking last year. Ran mini sprints with motor cycle engine. Keep having issue at the beginning of the year, parts failures rough races etc. One day was talking to his grandpa about his harley and learned about the grimlen bell. Next race Dave had one on his car. Came back to finish 6th in points and won rookie of the year. Now he races a pro challenge truck with a motor cycle engine and the bell is on it.
2 things though the bell needs to be present, can't buy your own. Also it mounts to the lowest point on the car where the grimlens jump on at.
