It all is a bit confusing isn't it? Think of trying to drive the car with the impact wrench, the rpms just aren't there. Power is a measure of work over time. An impact has much less power than an engine. Tho an impact can instantaneously do as much work as an engine they are not equal. I could be wrong here, just an opinion.
