UNDERDRIVE PULLEYS 924S / 944 ALL / 968Lindsey Racing's Billet Aluminum Underdrive Pulley's make additional HP and save you wear and tear on your accessories.
Since you can easily turn your steering wheel at idle RPM, there is nothing saying you need any more power steering pump speed at higher driving speeds. So why spin your power steering pump any faster then necessary. Since the power steering pump takes power to spin it, by reducing the drive ratio, we turn the pump at a slower speed thus using less horsepower.
Same goes for the alternator. And if you're still running the A/C, then same goes with it as you will be spinning the A/C compressor slower as well due to the smaller crankshaft drive pulley.
