The picture of my friends car started with breaking the rear gear on launch, shocked the driveline, the rest was a huge learning experience. Chuck Lofgren was at the track that day and came by to inspect.... and gave us a valuable lesson on what happened.

Years later the same thing happened to my cousins car at MaTS... drum didn’t explode, but broke the gear on launch and hit the trans so hard it broke the case and split the ring holding the rollers.
