I do disagree with you on that point. The advantage to the alternator is a better service interval of the unit and proper charging of the battery. The alternators do not charge well at especially low engine rpms. Especially when the pulley sizes are geared to slow them down too.

You have to watch what you are driving the alternators with. You want as much speed out of them as possible to get them to work correctly. I don't think there is anything that can be done to them to produce power at lower rpms. That is just the nature of them. I have seen speed curves on the 10si. I will have to find it again and post it.

I have an alternator on a M and a Super A. Neither of them charge well at low engine speeds. I have taken them both in and had them checked. They put out well within the range of what they are suppose to. You can watch the needle move when they are testing mine vs. new ones. They perform the same.
