Quick question, I am currently looking at two high output alternators for my vehicle, a 200amp and a 250amp. I have been told the 200amp will do more at idle (about 800-900rpm). is this true? I figured under the same theoretical load at the same rpms, the 250amp would do a little more power. Please enlighten me! Thanks!

some alts don't actually start charging intil your doing like 2000rpm or higher.

What brand alts ? In a normal situation. The bigger alt would put out more at idle than the smaller amped one.

that's what I always thought. it will be a completely rebuilt one from a local shop that has done work for me before.
