Also posted on VCA and Viper Alley forums:

My alternator on my 1996 RT/10 has packed in.

Is there any advantage in getting an uprated one (I have a Paxton system running 6-7lbs boost) or should I just go for stock?

Thanks in advance.

I'd stick to stock.  A larger alternator would have a bigger loss to the power and add more tension to your assy drive belt.  Unless you've got one of those massive stereo systems that require twice what the stock alternator puts out, I wouldn't bother doing anything except replacement.  I've never felt a need for more electricity.  I have a Roe blown GTS and a TT GTS.

Both have HID headlights which reduces the power consumption (lowering consumption is the same as increasing alt capacity).

Loss would be minimal, and more is better (ampacity wise). In traffic, lights on, rad fan on high, a/c going, stereo on, fuel pump(s), etc. I say go for it. Upgrading is always best and why not build in some extra capacity for upgrades down the road? When you build a house, you don't use a 60amp service anymore, 200 is about the minimum nowadays, the analogy is apt. Stock is just the absolute minimum that they could get away with when the car was built, no extra capacity built into the system. A new battery while you're at it couldn't hurt.

Yes if alternator is taxed to the max all the time its not good for any thing , ignition will suffer , fuel delivery ,etc.
Jim had that problem on his , car running poorly at mid to high speed , turns out alternator weak voltage down around 12.4 under load for any distance .
 Probably little difference cost wise if thats a concern .
No more h p loss than stock unless you can use the added output , it will only draw what you need at any given time .
Great idea if you are upgrading computer or fuel pumps etc in the future .
