when you drop the clutch off the line (standing start) or during a shift at high rpm (and hp). Lots of little springy bits inside there that will want to twist out of position. That said, with a non-DMF, i.e. a 7A or 3B flywheel, there will be issues with the springs in the clutch disc being able to absorb the shock. They too will have limits and will break or come out of position, potentially jamming the clutch, at some point with higher hp and torque and violent gear changes and/or starts.

The intent of the springs in the DMF or in the non-DMF clutch disc is to absorb some of the shock so you don't damage the transmission, drive shaft joints or the rear diff. Apply enough hp and/or torque and eventually you will break some or all of the above. Weakest link theory.
