Rev the Nuts Off

To race an engine, usually out of gear, to speeds at or past the rev limiter, making the engine emit a dramatic cacophony of high RPMs, exhaust noise and parts rattling from the vibration of the engine being put to it's limits. To run the engine at such high speeds that the vibration risks the engine coming apart catastrophically. To race an engine to the point where the vibration loosens the nuts and bolts holding the engine together. To push something to it's breaking point, or past it's safe working limits.
