I was working the starting line at Jackson County Sports Park at a NHRA points race. My buddy Warren was standing next to me. A Chevy Camaro modified car was doing a burnout and Warren fell over and the camaro went silent. The idiot had drilled holes in a stock dampner for a crank trigger. It exploded part of it was embedded in the concrete starting line and part of it took a chunk out of Warren's prosthetic leg. We were lucky that day.

I used to run the BHJ aluminum hub dampner on my stocker engines still have one in the shop. Never a problem.
