Probably not a lot. Now that we have all these major advances in electronics (lights, sound systems, etc), alternators don't have much work to do as before. If you dumped the water pump off that belt and converted it to electric, you would gain quite a bit, but I doubt if you would notice the difference...

Stereo's are no more efficient than they were 10 years ago.... and if you go back 25 years ago people were putting in smaller systems, and thus a smaller load. The past 25 years has seen more and more electronics go into cars just to keep them turned on.... There is a ton of overhead spent electrically on computers.... Compare a domestic car from the 70's to a modern car.... Check the amperage draw while they are turned off... the 70's car will show about a milliamp due to a clock needing power... the modern car will be 5-20times that. That's when its turned off. Furthermore... alternators in modern cars aren't built with as much headroom as they were 20+ years ago. Things are getting harder. |
