And yes you should get a new belt. The existing one would work but its not recommended. The tensioner usually has an indicator or notch on it that shows when the belt has stretched too much and needs to be replaced... changing the size of the pulley and using the same belt would throw that off... As for what size belt you'd have to figure that out yourself. Mark where the indicator is now, put new pulley on, get a belt a bit shorter and look at it.. if its still not lined up try an even shorter belt, until you find the correct length.
Go to an autoparts store and do it there, they should let you try a few different belts.
How much is that pulley gonna cost ya. I'm currently looking for a smaller pulley myself. Have a 48mm or 1.9" pulley now looking to get like a 44 mm pulley or something. Thanks man. Sorry I have no input for ya as I have/had the same questions
1. It will improve the amperage because the rpm of the alternator will increase. Depending on your alternator you could gain quite a bit of low end output.
2. It depends on how tight your factory belt is. Most vehicles have a lot of room to play, if you don't want to spend the cash up front I would try your current belt and buy a smaller one if it isn't tight enough. The difference is probably about 6mm, and most vehicles will have no problems.
3. If you need a smaller belt just ask the parts store employee for the next size smaller. Napa is great with that normally, where many places can only search by part number.
20 plus shipping is a good price, zack I wish the 44mm you're looking for was more common and less expensive.
the 44mm is about 1.732 inches so i wouldnt think there would be a huge difference between the 1.75 and the 44mm.
Thanks Troy.
I noticed that my voltage goes up to peak voltage by giving my car just the slightest amount of gas. So hopefully the smaller pully will do the trick. If it does it should completely solve my electrical problems
It may. The 44mm is about 9% smaller. Like I said 4mm isn't a huge difference when you look at as a number, but 9% is. You will gain some output at idle, maybe 20 amps or more depending on the alternator.
Yeah idk who you are asking either, but I have a 99 olds alero. I think I have 54mm pully currently so even going to the 46 should make a good difference. I will probably have it this comming week.
I wish so badly that I owned a 2000 suburban and could just get Troys 4 alt bracket lol.
I was saying Zack should go with the 44, but MD with the Mechman. Hope it helps fix both your problems. MD buy a suburban! Really though I'm working on tons of brackets so it may not be too long before one is available for your car.
I have wanted a suburban for the longest time, can afford one ATM
But my dads engineering firm might be selling a 00 suburban 2500 that they used for survey and they usually sell them pretty cheap because they are trashed on the inside, but might make for a nice project. The last one they sold was the same and i think they sold it for 3 or 4 grand and it only had like 88000 miles on it. But it would be a ton of work. the whole inside would need to go or be cleaned up and it doesnt have power windows or locks} ftl, but I could probably install some if I wanted.
Got my new pully. Its slightly smaller than my current pully. Only trouble is now i need to go out and buy an alternator pully removal tool. Unless someone knows how to do it safely and without buying any special tools.
You can either take it to advance or a tire shop and ask them to pop it off with an impact wrench. It probably takes a 7/8 socket. Most places will do the swap for free or like 5 dollars.
If you have an air compressor you can buy a used wrench and socket set for around 50 dollars if you shop around.
Well I went to Murrays/Orielys and they said they would do it, but I would have to take the alternator off and bring it in... Well I cant do that since I only have one car.
The nut on my alternator is 24mm and it is threaded to a bolt with an allen head on it.
What output alternator is that? After seeing the picture I'm going to agree with ms, if you don't have enough output after swapping pulleys upgrade to the ad244.
I would try another shop to see if they'll do it if you remove your serpentine belt.
I got it from Motor City Reman. It is supposed to be 200amp, but I cant be sure since it came in some random alternator box with 200amp litterally written on it. I dont wanna trash talk MCR, but Im not sure if I would go with them again just because I am not positive what they gave me. I went with them because glasswolf recommended them, they were the least expensive 230free shipping, and I wanted to support a local business.
Troy, thats a truck alternator. I dont think it would fit.
My cousin is a mechanic I'll probably have him swap it out for me this weekend.
a CS144 can be put on most vehicles with a CS130 stock, just have to get one with the correct mountings to match the stock one. as long as the clearance in the engine bay is there it is easily done. just need a longer belt. but in your pics it looks like space is limited so maybe on yours it can't be done.
" I wouldn't go with them again just because I am not positive what they gave me. "
So you'd be happy if they stamped 200 amp on the case or something?... you still don't know whats actually inside it... it should look just like the stock alt since it's built in the same case, just beefier internals.
Whats up Snow? havnt talk to you lately whats goin on.

I have money now lol... well had money, I was working 40+ hours a week all summer. Now that school has started I hardly work and the upgrading is slowin down.

Dude, I dont know what your talking about with this. Troy said to upgrade to the ad244. And the CS144 has less output than my alt(maybe not at idle, but Im workin on fixing that).

Well with it just written on the box I feel like they could have accidentally or intentionally put something other than a 200amp in the box. A birthsheet would be nice. But thats probably why the alternator is cheaper.
I got the new pulley on yesterday. Seems to be doing the trick, my voltage stays above 13.8 even on the strongest bass hits. Always at 14.2 or higher at idle with nothing playing(14.4 or higher while driving). My voltage was actually up to 14.9 for a while this morning.
Would a capacitor be useful in my situation to keep voltage more steady? Are there any quality capacitors? Most of them seem to be made by bad companies like boss, Lightning Audio, SPL, Volfenhag, power acoustic, ect. Obviously I wouldnt want to pay that much because I could just buy a better alternator.
I read all of Glasswolfs papers about capacitors and from what I understood it seems like one would work well in my situation because I have the charging system to keep the capacitor charged. I just need a little boost for breif periods of time when the alt is not enough to keep me at 14volts, but the batteries have not begun to help bacause I havnt dropped into the 12volt region.
As of now my voltage bounces rather quickly between about 13.8(it might go lower, but it changes so fast and my voltage meter has a digital display which makes it hard to read the difference between quick number changes so it always looks like 13.8) and 14.4(or higher) and just that slight change causes a little bit of headlight dimming
For the record I am embarrassed to even be asking about capacitors.
" Would a capacitor be useful in my situation to keep voltage more steady? "
Come on, have you not been on this forum long enough to answer your own question?
" Are there any quality capacitors? Most of them seem to be made by bad companies like boss, Lightning Audio, SPL, Volfenhag, power acoustic, ect. "
Hmm, all companies that make junk. I wonder why that is
That slight drop in voltage is a result of the alternator's voltage regulator not being fast enough to match the huge spikes in current draw from the amp, and there's nothing can be done about it. It's simply just the way the regulator works, it will never be fast enough. As long as you don't go below battery float voltage (~12.5v) your electrical system is working well.
hmm time to convert to a nuclear reactor? that is the norm, my old car at idle would dim a little when it went through its cycles if the ac would kick on or w/e it really is just your regulator not able to keep up. now if only we could make quantum regulators...
I havent installed it yet but I would be limited to 15.1 volts i believe resting in my competitions I rest at 13.8 with my ho alt so i was looking for an edge
i got my smaller pulley put on. its making a he1l of a difference not only at idle, but overall its performing much better. my alt has a set point of 14.5 so it doesnt go any higher then that but it stays at 14.5 much longer now. voltage is only dropping .2 volts once the alt gets hot. and drops to 13.9 at stops(when hot) as opposed to 13.1 with the other pulley. it was definately worth it
