High Amp Alternators?

Doesn't anyone make a higher-then-stock rated alternators? My system finally killed my alternator, and i've been searching all weekend. Doesn't have to be a direct fit (add additional 4 gauge wire, larger engine groud strap, etc). I just want an alternator rated at least 200+ (want 240).

I got the extra batter, got the caps. Just need the alternator. Google isn't turning up anything, and www.mralternator.com's email is down.

HELP

Also try this place, they are popular with the Mustang crowd.and of course, ebay.http://www.pa-performance.com/
[/div]That's a good link.

I jsut ordered and picked up the Cobra Harness plug (just longer) so I can swap it to a Cobra Alternator. Was just about to go with an AutoStone 130amp Cobra with lifetime warranty ($230).

But this website above has them for $260 for 160amps! I think I'll go with them. My only question is how are they on warranty?

Thanks man!
 
RE: High Amp Alternators?

They have a limited lifetime warranty and their alternators are new. The only problem I would see is dealing with shipping and turn around time as opposed to just swapping it out at Autozone.
Reputation around Corral.net is positive.

I paid 299 for a 200amp alt. I got it from alterstart off of Ebay. Had to run a 4gauge wire. Just sent it back today I shorted out the diode in it. So I sent it back for warranty work other that that no problems.
 
RE: High Amp Alternators?

caps are worthless sell them and buy an ultima

why do you need a cobra harness i put a caobra alt in mine all i had to do was clip a zip tie and reroute the wire a little 10 min job

I've been looking, and I did find this...

Pricey, but a good brand with a 125 amp output at idle and a peak output of 200 amps. I think the idle capacity is what's really important for most of our cars.

I'm kind of on the fence between PowerMaster and this one

from PA Performance. It has 80 amps at idle with 160 amps peak.
 
RE: High Amp Alternators?

By the way, why are you guys going with higher amp alternators? Are you running high powered stereos or electronics.....or just the old rule, more is better?
 
RE: High Amp Alternators?

Myself, it's performance oriented. My alternator does not provide enough juice at idle to run the cooling fan when I manually overide it to turn on at the track. I want to add even more load by installing an electric water pump and possibly an underdrive crank pulley. By my best calculations, I will require 55 amps at idle, and I am currently only producing 20-25 amps at idle. The cooling fan itself draws 20 amps, so at idle I am discharging the battery big time. Normal driving is not an issue.

Doesn't the HIDs use less wattage than halogens? BTW Ryan, get that alternator back yet?

Stereo, electric water pump.

I ended up with the local 130amp Cobra replacement. Figured with me turning this car into my daily driver, I couldn't risk it being down for a week or two while I get a "replacement" from the "internet". Would rather go and exchange it same day and throw it on.

And btw, the wires "could" be severly stretched to reach. But I didn't want to do that. I just extended the three 14awg wires for the connector (about 3"). Problem was the main B+ 4awg cable. Couldn't really extend that. It stretches, but it's tight.

Only two of the three 14awg wires for the connector are used. I think it's the middle one that terminates in the harness. You should also run a separate additional fused 4awg from the B+ post of the alternator to the battery when using a high output alternator.

[/div]Yep (another 4awg). But I just installed a Cobra OEM unit (130). No need to.
 
RE: High Amp Alternators?

Well, after much personal wrangling, I ordered one from Pa-Performance. All new 160 amp life-time warrantied unit(80 amps at idle) along with premium 4 AWG wire and fuse. That should put to rest any charging issues I may have. Soon, I hope to get the Odyssey drycell battery. Then onto the electric water pump. :9
 
RE: High Amp Alternators?

anyone know how reliable having your alternator rewound is? my plans are to pick up a used alternator (for $30!) from a yard and have it rewound to about 160 or 180 amps and just swapping it in place of the one thats on the car.

It is as reliable as the rebuilder and the quality of parts he uses. Besides the windings, you have the diodes, regulator, brushes and bearings. I used to rebuild older industrial/automotive AC-Delcos all the time. Most of the time the windings lasted forever.

I was told the OEM Gen1(Mitsubishi) alternators could NOT be rebuilt, something about the way the diodes were integral to the unit somehow?? I'll be replacing mine, so I thought the same - that is have someone rebuild the unit I have now to 160 amp specs.

I don't know about these starters in particular, but usually if it needs rewound, a re-man unit is a better deal.
