in your tests if you are using a belt tightened up to equal the tension in the car, you will find out if any power is lost due to the belt.
a belt when it's off the car usually falls to a natural position. when its in the car its tight around the pullys. perhaps that takes up some energy when it turns?
the folks here don't seem too concerned with that, I assume it isn't much.
in your tests you'll find out how much that is. let us know.
