is it safe to rev a car engine when it is fully warmed up ?
Hello. It is perfectly fine to rev the engine in your car as long as you are not over doing it or holding it at a high rpm for long periods of time. If the engine is functioning normally and is well maintained, then you should have no issues with revving it. When revving the engine you don't want to allow the engine to reach the red area on the tachometer. This can cause damage. You just want to make sure that the engine is well maintained and is in good shape before you do any sort of high revving on the engine.
