Show me a 904 front drum that has exploded from an over-rev situation behind a 6000 rpm engine. I've never seen one. For that matter, I've never seen a 904 drum exploded. Someone did destructive testing, maybe TCS, the RPM it took to blow a 904 factory drum was above 20K rpm, maybe 23000. Do the math, that's an input shaft rpm of around 9K +...
