Dual alt bracket for 99 s10 blazer??

Do you think with some crafty skills it'd be possible to add one while keeping the AC?

yeah

but then there is where metal fabricating comes into play

pm me if u want some help building one

Depends on how much space under the hood you have

you can do it without losing the a/c, there really isnt much fab, well if you are ok with just buying some flat steel for $5 and you might have to weld one, it really isnt hard at all

Awesome! Thanks for the link. That's almost exactly what I was thinking of doing. There's a lot of room up top, so if I modify the stock alternator mount a tad, then there'd be plenty of room for a second.

Just curious, how thick of steel do I need to make this out of? Would I be able to use aluminum?

Couldent put the alt between the stock alt and the ac compressor cause I have a egr valve. But I got it in anyways!

ever think of just putting in one huge alternator? not a regular body one but a real big one? I used a leece neville they are the best 300+amps with almost full output at idle. I would do that before I bothered to make 2 fit. http://www.prestolite.com/pgs_products/alt_search.php

How does it do at idel with a big alt like that? I heard the run like crap and is the only reason I wouldent do it as my blazer is a daily driver.

look at the charts they have on that site they do real well at idle. almost full output, I ran 1 of those with only 3 battereis powering 6 arc audio 2500s and it rocked. I had to mount it where the AC went then repiped a smaller AC compressor to the old alternator spot. leece Neville is awesome stuff lots of old school ham radio guys with 25kw transmitters would use them. If you are willing to make it fit and not have to screw around with 2 alts that have tiny pulleys that slip and slide it's for you.

check the output charts they have and note that is rotor speed not engine rpms and they do have nice full size pulleys but yet still crank out current at low speed. I see no better option.

check this one out and look at the size of it and the output curve almost full output at idle speeds http://www.prestolite.com/pgs_products/specs.php?item_detail_id=932&item=VLF2276-001

The only reason I was/am considering doing dual alternators is I may be able to get a second stock alternator for CHEAP, so it'd be cheaper to fab a bracket than to buy a bigger alt. Is ~210A too much for a single battery?

Got both alts in and running. Who else got theirs done?

sparkplug (and anyone else) -

i have a 1996 4 door, 4WD, 4.3L Blazer. I am desperately trying to figure out a dual alternator setup using two stock (preferably ad244) alternators. I am willing to give up A/C if necessary. Could you give details/pictures of your setup? It would be greatly appreciated.

Its not hard at all. you will need some steal and a grinder and a drill with some bits. I put mine next to each other and just used two ad244 alts and piggy backed the plug to have two. Pic...

Talk to some of the big name alt companies like Mechman, Ohio Gen, Excessive amperage, or Powermaster. They have some duel alt brackets and if they dont have the right one for you may be able to make a custom one.

they dont make one for the 4.3 had to get mine made a fabrication shop 100 bux.
