It is coming up on 3 years since I have had my 220A Alt installed on my 2005 xB and I just wanted to say a few things that I have encountered and experienced in this time. First off if you have a gen 1 xB and are going to install a large case conversion alt you will have to get a longer belt. What I have discovered is that by using the stock upper bracket that the belt over time stretches and eventually can not get enough tension on the belt as you max out the adjustability that the bracket will allow. All the rest of the hardware you will need comes with the alt so there are no worries there. The AVBM is awesome and it is a must to fine tune in your voltage output. I have had to slightly tweak the output for the different seasons because in the colder months the resistance was too low at startup and I was regularly charging at 15.1 or sometimes as much as 15.3V. My MS-8 processor does not like 15V+ and would make a crazy bad hissing sound at those levels. So the adjustability is awesome to have so that can be turned down a tad when needed. My output is always strong as long as I keep the engine RPM's up a little after it is fully hot in the hot summer heat of the south where I have lived since I have had this alt. I do notice that sometimes when slowing down and downshifting the RPM's will drop down 1.5-1.8V momentarily but it goes back to 14.4-14.6 where it usually is set at once I stop and maybe give the throttle a rev or two. All in all this alt is awesome and has met all of my expectations. I am working on getting a new upper bracket made so I can get a but more tension as to eliminate the cold start engine belt squeal. I hate hearing that in the early morning hours when I have to leave for work. Here is a comparison pic to the stock alt for reference:
