Permanent Load Harmful?

Evening, I have read through some forums and have often read that permanent full load is harmful for every car. Durable full load is harmfully clear when you hang at the limiter with the speed and the accelerator touches the ground. But how does this work when I give full throttle, but the speed as with me lies at 4100 rpm? Is this also harmful or not? With my car is at 220 close and there is the speed just at 4100. Bad or can I do it quietly until the tan k is empty? Thanks euuuch
