Upgrading alternator

[GoodmanOX]

I want to upgrade my alternator. What brand and model/specs for a 99 Tahoe 4x4?

 

[970Tahoe]

Best bet that is cheap is to get an alternator from an '03 that is 130amp. bolts right up and has the same plug too.

Just need a new belt IIRC

 

[yukonjon]

Do you know what belt you will need or just measure and pick?

Stock replace for a 99 obs is 105 amp or 140 amp.

Search around SummitRacing.com, they have quite the selection of alternators from all different price ranges. I'm considering a Powermaster to replace mine.

Not sure of what your electrical needs are, but I've been very happy with my 220a ** alternator from Iraggi. It's a large case alt that fits in the same location as factory. Give Dominick a shout:

What about this one? http://www.summitracing.com/parts/PWM-58206/ anyone use powermaster?

 

[HuskerHoe]

not to be a dick, but why in the world would you spend $280 on a 150 amp alternator when a 140 amp reman one is less then half that?

If you're looking at spending big money go with a ** Iraggi or something equalivent

You're not being a dick. I know nothing about this and am looking for any kind of info leading to the best replacement alternator. I want to upgrade to a quality one, not a reman. My experience with remans are more nothing to write home about but, thats another story.

What are the benefits of upgrading to a 220a vs a 150?
I do plan on upgrading my stereo but nothing too drastic, replacement speakers and a sub with new headunit and one amp.
Performance wise, what will upgrading do for me?
I am also planning on upgrading my ignition to, sooner than later.

Sorry for all the questions
Thanks

Hey Tiger, its Tigwldr. Hows it going?

 

[HuskerHoe]

Basically the benefits of 220 v 150 are the added electricity to the system. If you are running multiple amps pushing 1000 watts or more then a 220+ is necessary or you will see your lights dim because the amps are using up all the power.

I'm running 2 12's at 800 watts with a stock 140amp alternator and it works just fine. No dropping of voltage or dimming of lights.

If you are just planning your average stereo, a stock 140 amp is more then fine. An Optima battery is a huge plus tho.

I know you said you dont like reman alternators, but remember, most auto parts offer lifetime warranty on even remans. For a fraction of the price of a brand new one. How can you beat that? Take your savings and spend more on your stereo or battery!

Thanks for the info, I appreciate it.

My experience with reman parts have been pretty bad over the last few months.
3 starters
4 tensioner assemblies
2 alternators, going on 3
2 idler pullies
2 waterpumps
I've just about had it with reman parts, to me it would be worth it to spend the extra coin on a quality product install it and forget about it. I'm having issues with an electrical problem now that I'm trying to sort out. My battery dies every couple of months without any signs. I started a thread about it.
Thanks again

I was just curious, don't really know too much about them. I am planning on doing the "big 3" upgrade here soon and figured I'd toss an new alternator on while i'm at it. The stock is 105amp right? I'm looking at throwing some lights on the roof rack i'm builiding and some lightforce's on the ranchhand that i will eventually procure. ha. Sounds like iraggi is the new hottness, eh?

 

[fyremanpat]

what about an overdrive pulley?

Wow, just out of curiousity where are you getting your parts? And what kind of warranty did they have on them? I would be frustrated too, they should not be failing like that. Is there some other problem causing them to fail? Link to said thread?

Stock is either 105 or 140

Well if you have the money to throw at it, a High Output Alternator is never a bad thing. But for some guys(like myself) its just not worth the extra money.

If you want the ultimate electrical system; Big 3, ** Alternator, Optima battery. You will be able to run a big stereo and lights no problem.

I purchased them at Advanvced Auto. They all have lifetime warranties, thankfully. I had replaced everything because of one squeak, couldnt find it, shouldve left it alone but decided it would be preventative maintanence, that turned into a nightmare. No other issues after buying my parts online and at AutoZone. Oh I forgot to mention 1 steering gear box, that was fun.

Here's that link.

I would like the ultimate electrical system.
What is the "ultimate 3"?
Thanks

there are severl posts on here about the big 3. basically you replace the wiring with bigger stuff from the battery, alternator, and ground. some claim it adds HP and stuff, but i'll believe it when i see it. I just want to do it to know that i can support the lights i'm going to put on. I do have the optima red top already.

 

[blueflamed03]

Powermaster and XS Power make great alts.

 

[HuskerHoe]

No no no no no. You are missing the whole point of the Big 3. It is an ADDITION to the factory wiring. Two Grounds, and one power, going to your alternator. Using 0 or 4 AWG, it reduces resistance and allows current to flow better. Kinda like upgrading the exhaust.

You can do it either way. Theres only so much current that can run through it. To be honest its better to do away with factory wiring seeing how most of ours is 10+ years old.

 

[GoodmanOX]

why wouldn't you replace the old factory crap?
