Bearings 1st time. Started whining and then fan started hitting case. Then rectifier or something next time, then not sure what it was the last time.
I lucked out and found a used 270A DC locally for $200, was in near new shape, and grabbed it, swapped it on, then sold the repaired mechman for $350.

I'm really happy with my Powermaster XS Volt unit. I don't have a Corvette anymore but I believe the one I have would work on most LS vehicles as it fits in the stock lower drivers side bracket/mount. I also went with a 14V XS Power battery when I discovered my fuel pressure issues were due to my battery voltage dropping into the 10's. I have 3 525's, dual electric fans, etc. The 14V upgrade was absolutely amazing too. Very happy I went that route, and honestly kind of wish I had gone 16V. Still an option in the future with just a battery swap though.

Just to update; At ~10k mi. my 170A Mechman started dropping voltage. Would slowly drift to 12.Xv (battery voltage] occasionally - often returning on it's own. If not a restart brings it back up. Ordered me a 270A DCPower...the Mechman will be sent back under warranty. And then up for sale.

As much $$$ as these 'premium' aftermarket alternators cost (ie: Mechman, DC Power, etc) ... I think that if the alternator on my C6 ever **** the bed, I would just get a lower priced alternator from Autozone or someplace like that.
They still have a warranty. If the thing don't work right, just go back to the store and get another one on there dime ... not every Autozone or Advance Auto alternator can be bad out of the box.

Oh, and the reason I would look to Autozone or Advance Auto for a replacement alternator is because they are local .... If the alternator don't work right out of the box, I can just bring it back to my local store and exchange it. No need to send it in the mail back to someone like RockAuto and wait a week or more for a replacement.
Just my opinion.

I had an alternator catch and fire on the dyno, maybe that’s what your thinking of? Unreal might have as well though. Mine was this bullshit company called “power bastards” and they were definitely some bastards. 2nd alternator they sent also seized and damn near caught on fire. Ended up just eating the $500+ for that garbage.
I know have a DCpower 185A 👌🏻

i got a 250a (or something) from dc power and its been fine, had to shave a little off the alt bracket to get it to fit, but run fine for 1k miles so far....
i will say that i had to bother the **** out of them to get it to ship... and it took like 4 months....
quality seems fine though... doesn't heat soak in traffic or anything... 13.8 constant....
my mechman was great in my z06 as well... 170a... put i think 3 or 4k miles on it without issue....

How long ago was that? They said 3-4 days and out the door when I talked with them a few days ago.
And stock replacement sizing...
skydaman above - mentioned using an OEM truck alternator that bolts right up... but I need >170A

They make truck units up to 250A for roughly $125, but I also changed my bracket to an ICT Billet unit.

Nation's makes a nice unit and has the best installation instructions I have ever seen. The mechman had the highest Amps at idle I have ever seen but did not hold up in long run. I think they fixed the regulator issues though.
