Has anyone added a second alternator to their 3x00?

Nope. I'd like to think it'd be easier to retrofit a 130-145 Amp alternator from a 3400 equipped minivan!Brian

I'm already running one from a Venture - 125A. Stock in my Impala was a 105A
What Van has the 145Amp?
Still doesn't solve my problem though. I'm needing 97 Available Amps (1400W/14.5) for just the Audio equipment.
I have a 200A HO Alternator, but I have to Rev about 4,000RPM before I see them. At idle it also only puts out about 12.5V - Seems to be rather shitty. But I have not found any other alternatives other than stock replacements.
I'm just trying to think of a placement... I'll do damn near what ever it takes... I want my Audio.
Edit: Short of having a custom alternator wound....Last edited by Khipset; 08-23-2010, 07:18 PM.Comment

but then you put more load on the alternator when it has to charge them back up.Originally posted by bszopi View Post
If you can find the space for a 2nd alternator just make some brackets and mount it up, people do it all the time. There should be a way to trick it into "1 wire mode".. sometimes the newer ones need to have a small load across 2 of the control terminals, i've seen people use light bulbs and resistors for that.
for your HO alternator, does it have the stock sized pulley? I think it was MRZ that makes a smaller one that would help it spin up a little faster.Comment
