Ok so ive heard of a few people who swap out their A/C compressor to add in another alternator. I'd like another alternator, however I don't wanna lose my A/C (its a necessity.) So I was wondering if there was an alternator that would fit in where the smog pump fits? Is it a special order type item or is it off of another vehicle?

Thanks in advance guys.

 

Why do you want dual alternators?
I'm using a larger output alternator to get more juice, 140A out of a CS144. It slips in nicely in a V-belt car.
Do a search on the electronics board to see the thread I posted in. Lots of good pictures and info if you're interested.

 

i get a substantial parts discount to stock replacement parts. bigger alternator is not stock and i then have to buy an AIR delete pulley.

 

Stock replacement parts? The CS144 I mentioned is the stock alternator for a 1994 Chev lumina van. Or Caprice, or Pontiac Transport van, etc etc. I got mine for $50 at an auto wreckers, but if you get a discount at a parts store you could get it new for.... $150?

Oh, I thought you had V-belts, in that case you don't need a "delete" pulley.

 

chevy lumina is a FWD car right? what van did you pull it out of?

 

the Lumina is also a van, its real name is the "Lumina APV" but for all intents and purposes it was a van on a Lumina chassis (twas an ugly beast too.)
So will the Lumina van alternator fit a serp belt setup? (For clairfication, the engine i'm puttin in is from an '88 L98.)

 

Yea, there's a Lumina car and Van, don't ask me why, neither one was particularly special.

They use a serp belt stock. I swapped the pulley to a V-belt one and it fit into a V-belt setup with only minor tweaking on the brackets.

I think it's an equally common swap on serp cars, but the bracket modification is slightly more involved. Actually, most information online for this swap is directed at swapping it onto a serp belt car.

It also requires one 35ohm or thereabouts resistor to be soldered inline.

Do a google search on F-body CS-144. There's a thread on here, and a tech article on another 3rd gen camaro website with a lot of good info. I'm at work now, but if no one can find it I can dig it up later.

Also, there's a few versions of the CS-144, I think a 105A, a 120A, and the 144A version. I forget now how to tell which is which (big surprise, it's a subtle difference...) But the way to ID them is listed somewhere online...

 

or you could go to o'riely's auto parts or autozone and get a rebuilt 100A for 60 bucks. They go higher too. Why do you need such a powerful alternator? subs or something?

 

yeah i got a couple of 12s and i use em all the time (always have it cranked up) so the alternator get quite a workout. I figure 2 alternators running 90 A would last more than twice as long as one, and how cool would it be to have the only camaro on the block with dual alts?

 

Two 12s on any sort of normal Amp won't tax your charging system much. If anything, upgrade your big 3 and call it good.

 

more alternators = more drag = less power and economy. Just get one 100A and it will be fine.

 

Good point, I guess ill see if my local alternator shop has anything.

Thanks for the input guys.
