|
|
Many years ago some people installed American car or other non-VW alternators on their Baja Bugs for running many lights.
This may date back to the days before VW switched to an alternator to replace the out dated generator.
So, I'm thinking a modern, high amp alternator may be a cost effective alternative to an expensive, high amp aftermarket alternator.
Of course, it wouldn't mount where a stock VW alternator mounts. Custom brackets would need to be fabricated and a longer belt or second belt would be needed.
I'm wondering if anyone here has done this. How do you like it?
Here is a picture of an old kit I recently saw at a VW Show. I didn't buy it. Probably should have.

Saw that. Not really the information I'm looking for.
Maybe someone who is using a non VW alternator could post pictures showing how they mounted it and wired it.

I wouldn’t do it. Go the other way, vw alternator, and modern LED lights. _________________ He said to them, “But now if you have a purse, take it, and also a bag; and if you don’t have a sword, sell your cloak and buy one. Luke 22:36

Looks like I might need to search through some old publications from the '60s and '70s for the information I'm looking for. _________________ 1957 Vintage Baja Bug.

This version looks like what those brackets you found do, but I like this better. IT doesn't rely on that crazy long belt all the way across the engine..

Here are a few.. google image search of chevy alternator on thesamba.com
just type your search terms into google, space, then site:thesamba.com
https://www.google.com/search?q=chevy+alternator+s...mp;bih=621
This trick works for any website.
The mount kit you showed only supports the front of the alternator.. seems like you would need to brace the back too to keep it aligned with the belt. |

The more you reduce the belt wrap angle on the fan pulley, the sooner it will slip. _________________ 1800 Type 4 Berrien 295

Why not just use a air condition pulley, then you would not have to stretch a belt all the way around all three, it might turn it a bit slow but it wouldn't be as much off a drag at idle and up until you get into the mid-range. _________________ 74 CLASS 11 LOOK-A-LIKE

I saw your alt blew out the other day yea? Switch over to a 38 amp generator. I've had less problems with my 38 than the 6 alternators I've burned. _________________ Wash your hands

That would burn a motor up in short order. Think of it this way, I've seen built motors make an extra 15-20hp at the tires by disconnecting the fan belt on an ACVW. So if that fan takes at least 15hp to turn, how is that little bit of belt wrap going to do the job? _________________ "In any racing engine, the nearer you are to it disintegrating, the better it's performance will be"

You want to stay away from anything newer than 2006...I saw a video on YouTube where the guy was saying that for fuel economy, modern alternators don't put out 14.1V anymore, they put out like 13.2+,somewhere in that neighborhood. ..just a FYI _________________ Never be a follower...Do your own thing, make it your own! |

That’s probably true, made possible by the fact that automakers have embraced LED lights, and modern electronics. High charge voltages aren’t needed on new cars anymore. _________________ He said to them, “But now if you have a purse, take it, and also a bag; and if you don’t have a sword, sell your cloak and buy one.

How about a serpentine setup with a longer belt for the 2nd alternator?

That would be the better option, because you can snake the belt around to wherever you mount the second alternator. You just need to make sure you have adequate belt wrap on the stock generator pulley to keep the fan spinning. _________________ "In any racing engine, the nearer you are to it disintegrating, the better it's performance will be"

How about placing the alternator like a power steering pump on an offroad racer? _________________ Richard

AC pulley with secondary belt is likely your best bet. |
