I'm just wondering what the purpose of removing it would be? Does it add 5 hp?

Not at all, *IF* you live where there is no snow, or rain that can freeze, or gravel, or sand, or where a bit of gravel may kick up off a construction truck, or ...  

The cover is there to protect the belt. If a foreign object like a small piece of gravel gets in between the belt and the pulley, it can make the belt skip a tooth (or two or three). When that happens, valves hit cylinders and you are rebuilding an engine.

Now, you may drive it for years before that happens. Or it may be just a day or two.
