He uses the smaller pulley to mimic a high output at idle and cruise. Also the comments of other buyers show it's within stock ratings when they had it tested.
If it's not the eBay one , the smaller pulley may only help at idle as well but the maker of the alternator can give you the specific output at specific rpm ranges.
I bought it from the db website. Got it all hooked up with the oem pulley. Is it same rating with the oem pulley or did i lose alot of the amps? Its 220 amp one
