Locally a guy was using a stock pulley and it broke and he drover over it at about 100 mph , went for a bad ride .. car was destroyed , he got some severe bruises from crotch belt
About 3 years ago, my stock crank pulley exploded on the top end and My slick just caught it on the outer edge. Boy was I lucky nothing bad happened. I do run tubes and luckily it sliced the slick but not all the way through. That could have been real ugly.
