can I get a smaller alternator?
I searched and it seem there is a TON of info for upgrading to a bigger alt. But I want one that is smaller and lighter.
I see alot of guys upgrade from the older CS130 to the CS144 140amp. But my question is can I downsize to a smaller 85 or 100 amp cs130? I have my current stocker relocated down low so any other alternator would have to have teh smae mounting points. Anyone ever go smaller? What did you use? |
Re: can I get a smaller alternator?
Late model cars need large alternators because of the large amount of electronics they carry. The older TPI cars use a smaller case alternator that is available in an 120 amp version. I wouldn't install a lower output alternator on a street driven car. If it's a track only car you could get away with 60 amps or so, but I wouldn't try it on a street car.
Why do you want a smaller alternator anyway? |
Re: can I get a smaller alternator?
well my current stocker has quit... actually it went out a while ago but I am just getting around to it now.
It is a race car, no street use at all. I figured if I have to replace it I might as well save some weight and get something smaller and lighter. A great deal of the electronics in the car are no longer there. No radio, heater, ac, defroster, ect... But all the engine related electronics are still there. I am just looking for a replacement that will cut a few pounds off the front end. And by the looks of it I might be able to get an older 100 amp unit from a TPI car in chrome for a reasonable price... and they only weigh 12 lbs;). I just dont know if it will bolt up... I guess I really need to see one up close and personal to know for sure. |
Re: can I get a smaller alternator?
do you have any pics of your relocated alt? I am going to put mine down where my air pump used to be and was wondering how i was going to do that. Did you buy a kit, or was it a homemade type thing?

Re: can I get a smaller alternator?
The TPI unit will bolt up with minimal modifications. I believe the distance between the two mount bolts is a little shorter.

Re: can I get a smaller alternator?
Sorry no I dont have any pics. But if you search under SJM I am sure you can find a link to the site. I bought the relocation bracket from SJM. It relocates it to where the a/c should be. Since its a race car I dont have anything else, just an alternator. You could make one yourself but I just figured it was easier to just buy one already made;).
I think if the mount bolts are closer it wont work, even if they are still clocked 180* apart. I still need to have the mount points the same or I will need to make a custom bracket. |
Re: can I get a smaller alternator?
i guess you could put it anyway you want as long as the pulley and belt line up, right? I plan on putting mine where the air pump was. I guess I will make a custom bracket out of some thick aluminum

that is nice

Re: can I get a smaller alternator?
Yeah that is a nice alt but its just waaaay out of my price range...
I did some more reasearch and the cs130 is avalible with the same mounts at the cs144. I can also get it in the 85 amp version and cut a few lbs off the front end and it will bolt right up. I'm going to order one and see how it works out. I'll post back with the results. BTW, I also found this on the net. http://www.alangrovecomponents.com/LT1.htm $60 for a low mount alt on an LT1 isnt bad... |

Do you or anyone know of a bracket that allows the alternator to relocated to where the old air pump was located? It allows you to keep the AC supposedly. |
Re: can I get a smaller alternator?
Brettinator, your box is full...
The bracket I used was from speed specialty and deletes the A/c. They have another one that goes on the other side of the engine that doesn't. Here's a link: http://www.speedspecialty.com/store/...t1altbracketV2 |
Re: can I get a smaller alternator?
I am running an alternator from a 94 Caprice with the smaller alternator. It is a 105 amp unit and bolted in fine. I had to use my pulley though.
ost parts stores stock this one. Be careful because there are different styles availible for the same year. maybe this link to NAPA s website will help the part number is BSHAL8663X http://www.napaonline.com/MasterPage...rnator+-+Remfd |
