bump....i wanna know this aswell.
Why do you need a bigger one for? Decrease gas mileage, have extra money to waste?
First off lets say company A puts an alternator in a car and the car will use up to 100amps. Now do you think the company will put a 100amp alternator in the car, no they will increase it usually by about 30 or 40 amps, so they will use like 140amps.
By the way adding a giant alternator and changing to a bigger pulley size will decrease gas mileage slighty because the engine has to work harder now. Now I know some people wil be will be like BS man, I'm not talking about 3-4 mpg, I'm talking about less than 1 mpg, but it still does decrease it, and overtime it will add up.

You can overload your battery and fry your electrical system doing this crap.

Not true, the battery wont take anymore that what it needs. You wont fry anything, they will just piss away money thats all.

I don't know what's the biggest alternator you can put in, but I am curious...
Why do you need that much power? What are you planning on running?

actually its their money, why do you care?
Whilst agreeing with Rob S
For those of you who really want high output, or are just interested
I have one of these ZENA 150 Amp welders which can be run all day, they have a 100% duty cycle.
I run this from a 10HP snowblower engine and at high output you know the engines working.
Zena also makes High output Alternators for car Audio Systems:-

There is some interesting reading here
If you really wanted to you could use the 200 Amp version or a combination of 2 or 3 200 Amp alternators, if you had the room and have 400 or 600 Amps-to infinity and beyond.
Is it not about 2 horsepower in from the engine for 1hp/ 746 Watts out, from the alternator?
You would just have to have some very large gauge cables to handle the current in both the positive and earth/ground cables.

wow, those are some exspensive alts. But what is the biggest, highest rated DIRECT SWAP alt available?

why do you wanna do this uhh?
what's the point? uhh?
do you drive a jet plane or something?
is your engine so big that you need a generator?
maybe you're living in your car, and then you need a
bigger battery to last longer?
Bigger alternator? why Bigger?
does size matters? is that what it is? lol
I'm just joking hahahaha
ohh, and to answer the question:
I don't know,
look it up on the internet because I don't know and I'm not the only one who doens't know. but you might want to also upgrade your electrical parts if you want to push so much power.
All the alternator does is to keep the battery running while the car is moving.
The battery runs your radio, ignitions, sparks in your spark plugs, headlights, lights, electrical stuff like power windows, power locks, computer, ect... and your battery never dies while the car is moving thanks to the alternator.
now if you leave your lights on, the battery dies because there's no alternator to keep charging it.
Good Luck!
