HO alt. versus alt winding

[twes244]

I had been doing searches on here for a few months before i got my system and this is my first post, so forgive me if this comes off as noobish:

I was wondering if there are and disadvantages to getting a stock alternator wound as opposed to buying a high output alternator. For example, would a wound alternator lose it's increased capabilities a lot faster than a h.o. alt? I am only running about 700 watts RMS, which will later be increased; though i don't plan to run more than 1000 in all likelihood. I used to only get dimming, but now it seems that my subs shut off a lot more frequently ( not only at high volumes ). If it helps you at all my car is a 1995 Chevy Lumina.

you can only cram so much into the stock casing, so if your alt isnt very large you cant get it wound to as high of an amp alternator as a larger H.O. replacement might have.

dude! liverpooly ny! ROCK ON!

where do you live?

Thanks Moe. Assuming both could put out enough amps to handle the load which would you recommend?

- off of Soule in Pinegate... nice to see a fellow Liverpudlian (i hate that word though)

I thought re-winding wasn't reccomended because the stock parts such as the bearings and fan could not handle the increased load for long? Cause if that's not the case I need to make a call...

Thanks for your input guys. I think I am just going to wait a little longer and get an H.O. alt. In the meantime I'll just put my subs in 4 ohm mode so they draw less current.

There shouldn't be that much of a problem with a 700W RMS load on the electrical system.

I thought lower ohm load (2 and 1) draw less power than 4?

wronglower resistance=more current

Yeah I wouldn't have thought so either, but when in 2 ohm mode it will shut off before it gets very loud. Its a stock 100 amp alt, but i haven't upgraded the wiring at all yet. I'll just do that when i put the new one in.

have you done the big 3? i'm running 800w off of a 70A alt. and i don't have any problems. after i did the big 3 the dimming all but stopped.

You can re-wind almost any alt. Problem is that you generally can't rewind them up very high (the highest I could go with my GM 105A was 140A), it'll probably cost you as much as a higher-output H.O. alt (the rewinding to 140A was going to cost me $250 //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif ), and when they rewind they generally don't upgrade all the components like a good quality H.O. alt would have.

x2 if you got the money just get a HO. all the bigger i could have mine wound was from 70A to 75A for $150. SCREW THAT!!
