[QUOTE="maylar, post: 949101, member: 541144"] Typically 50-60%. Not bad, really. Specialty units can be over 70%: [URL="http://www.wranglernw.com/ecotech/specs.asp"]http://www.wranglernw.com/ecotech/specs.asp[/URL] Yes, the power comes from the engine. A high output alt might have a bit more drag because of larger rotating mass but the alternator alone would probably not be noticed. The real power drain comes when you put load on it. Like someone said, 1 hp = 746 watts. Since an old VW Beetle was only 35 hp or so to begin with, adding a couple hp load with a big system is prolly a bad idea. [/QUOTE]
