Another Loyale! I like what you've done with the A/C. I pulled my Power Steering pump (and drained the lines & plugged them), but kept the A/C intact. The steering feels much better at speed, and is manageable with one hand in the parking lot.

I don't think you will gain much from using an electric motor to run the power steering, unless you have some variable speed logic so you're not running it all the time.

The alternator is only ~60% efficient at turning crank energy into electricity. So using an electric motor to run the alternator to power the electric motor... doesn't work. You have to take crank energy to run the alternator.

Over the winter I only ran the front belt, to the crank & water pump & alternator, and it worked fine. I think you can ditch your rear belt & save more drag.

Let me know if you have any questions about your Loyale! If your idle is too high you can put a "restrictor plate" in the idle air control valve, this really helps.
