746 watts is 1 hp, right? 500 watts may not seem like much, but if you don't have to generate it over a 400 mile trip, then the savings should start stacking up.

justme, if auto parts stores do sell the clutches separately, that'd be good to know. I've always been told I couldn't get one separately. Although, I may not have as much use now since I installed the underdrive pulley.

I thought I remember hearing that normal cruising typically consumed only 7-8 HP. (Obviously, steady-state conditions, and probably referencing a sedan.)

So saving 1/2 HP could be a large percentage.

A smaller engine car that spins its P/S up to 3k to 4k could be sending well over 1hp to the P/S pump.
Those small cars that spin 3-4k tend to only needs 10 to 15 horsepower to over come drag and rolling resistance and maintain speed. Removing a 1hp load off the engine could be pretty big, to a smaller car.

What are your gains with the underdrive pulleys, are they the Lightweight?

What happens if you're cruising down the highway and have to swerve?

Why? I've had my power steering pump disabled for quite some time and the only time I really notice the lack of assist is when the car is stationary. How about you? Have you tried it?
