Congratulations to D.d. Mahoney and his team for their Elite 8 win in No Clock Street on Friday. They put tons of work in during the offseason to rebuild a car after a crash late last season and the work has paid off. After some testing and just two races they’re back in the winner’s circle!

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.
