high output alternators

[cardude007617]

i know about the general companies that make HO alts for our cars like mr alt. but what about these 2:
1. http://cgi.ebay.com/ebaymotors/GRAND...spagenameZWDVW

and

2. http://www.motorcityreman.com/grandam-cs130d-2.html


i mean the prices are all pretty much the same +/- 15 bucks or so

mr alt-$225 for a 160amp (http://www.mralternator.com/alternators/grandam.html)
ebay-$220 for a 200 amp
motorcityreman-~210 for a 160 amp

comments please

Everyone has had good experiences with mr alt, I would go with him, id personally stay away from ebay if there are other options.. I orderd from motorcityreman and one of the guide holes that the bolt went through was a TINY bit off, took 5 minutes to fix and overall was very happy with it.

Do a search on irragi, a man named dominck irragi makes custom HO alts. I will get his email address for you if you like, he quoted me 350 bucks for a 200 amp, which i feel is a pretty good price for it being custom made, ive heard good things all around about him.

I am getting ready to replace my Mr. Alternator one with a new factory replacement. First the pulley I got with it was incorrect, so I put the factory pulley on it. It has never put out enough juice at idle to even run just my lights without them dimming, and this is with the power wire to my amp completely disconnected. It's fine at higher rpm, but ad idle it just blows. If I had an overdrive pulley or something that would probably work, but I can't find one.

I believe they put out the same as stock at idle (HO alts). Not until a little higher do they put out the full 160-200 amp w/e yours may be. Ive only heard good things about Mr. Alt. Zzp sells an overdrive pulley..

hmmm that doesnt sound very good.....^ i dont know, im kinda leaning towards MCR cuz its a little less money and jake had a good experience with em.
any idea where i can look to have mine rewound? and what it would cost me?

Motorcityreman were good people to deal with they always responded fast to my emails when I emailed them, one of the holes was just a TINY bit off, like I said we fixed it in 5 minutes its nothing major, if you were to buy one nd by chance have the same problem I could help you through it easily. No clue about having it rewound.

[cardude007617]

so ok, looks like im gonna go thru mcr i think. now, as i posted either here or on a car audio forum (i dont remember which) a while back, would adding a 2nd battery for playtime when the car off be "fine" with a high output alternator? like it really wouldnt put any extra stress on it?

[SSRacer]

I'll have to check Zzp for that overdrive pulley. I guess the alternator is fine except at idle. Did a search on here and found that it is a problem with a lot of even HO alts.

[SSRacer]

Just checked Zzp's site and only saw an underdrive pulley.

Maybe they stopped selling it, they recently also stopped selling the lowering springs i got off them, like the day after minea rrived they stopped selling them

[SSRacer]

Well that blows. I really don't want to go buy a new alt because there's not really anything wrong with this one, just needs more juice at idle. Zzp did have some inline alternator booster that is supposed to boost the output like .6 amps...not really sure how that works.

i got a an excessive amperage (EA) 200a alt for like $350 or something shipped... its been working good for me so far. Im pretty sure that pretty much all 200a alts put around the stock alt power at idle but they put out like 200a at like 2000rmps... or something like that.

[cardude007617]

sean, they still sell the overdrive pulleys, just look in the drop down menu under engien stuff i believe

[Ajaxus]

i actually looked into buying online but after reading about the possible problems you can run into..going to a shop and having them rewind the alt for a higher output seems to be more ideal. if you have issues you can probably have a warranty to fall back on and not worry about shipping time. i haven't priced it out yet since i can't afford it (will do so on the spring time) but i imagine it would be another good option than buying a whole new one online.

DOH! You are correct, I fail at life. I didn't notice the dropdown on the pulley page.

[cardude007617]

so ok, how many shops or like where would i go to have someone rewind one for higher amperage?

[Caleb]

We do custom alts at my work; Van's Electrical.

I'll see what you'd be looking at cost wise when I go in tomorrow, if you'd like.

[Caleb]

Well, the stock alt can be rewound to a max of 140A it looks like, but it would be flaky.

A pulley swap can net you higher amperage at idle, but the most the stock can reliably produce looks like 70 amps, and it won't be too happy doing it.

Your best bet is custom mounting a larger unit, but of course that possibly involves mounting another pulley, and ideally you'd line them up using a laser.

Major PITA, but if you want it done right...


I'm wondering about the claims from some of these sites. I'm doubting the units are cranking out as much as they're saying in actual use.

[Ajaxus]

If they lie you can get them on false advertising..no business really wants to be caught on that one because you can exploit it in so many ways.

For example I know someone that bought a car at about $3000 off the regular price because of a simple typo in the classifieds. (screw you bob before you reply)

It's a shame you guys can only get 140A out..I'm wanting about 150A minimum. Guess custom is the way to go then..
