I have a few questions.

1. How much amperage does the factory alternator put out at idle?

2. Where can I find a replacement higher output alternator?

Thanks!

The stock alternator puts out 140 amp max but not much at idle. WHY?

I thought the stock put out 120, but there is a 140 available for our cars.

I think 93's and early 94's had the 124 amp alternator, but late 94's on had the 140. If you have to get a new one just get the 140, it's a better part anyway.

yep, 140 is the best way to go IMO. that with an Lt4 starter, and an optima battery..should have no charging/starting issues for a while of course not sure what your issue is

93s had a 110 amp alternator. Mine put out 94 amps when we tested it.

I had a local shop rebuild mine for $150 to put out 170 amps. I think the 94+ cars can be built to put out 200 amps because they use a different stator.

basically the story goes that I decided to underdrive the **** out of my car. No charging problems... until I add an amp. Obviously the alternator will potentially need an upgrade to handle this. Driving I'm positive I will not have an issue.. idle is what i worry about. Last thing I want is to stall at a red light.

I put in a 200 amp alternator about a year ago and it drops low at idle. I've never had a problem with it running both fans, stereo w/ two amps, headlights, etc. all at once, but my stock alternator put out more at idle than this one does. I believe a lot of high amp alternators put out low power at idle. You might want all the specs before you buy a high amp one.

Thats funny, my 93z came with a 124amp alt...... And all the data I have seen, have been 124amp......

Now the V6 version used a 105amp.....

Did you buy your car new?????? Someone might have replaced it with the wrong alt.......

anybody use that 140 amp replacement that delco offers?

with my amp(s) i think i should be fine if I throw a farad of capacitor in front of it.. maybe more.

I'm also going to be upgrading my sound system, and adding an amp aswell as few other electrical components... ...I have an LS1, How much do those alternator's put out stock? Also where can I find a High Amp replacement?
