I had one of the 120 amp ones, lasted one drag week. Put on for 2015 dragweek did great, came home pulled the trans and motor didn't get it back in until right before drag week 2016, and it went out on the second day. So probably about 1300 miles on it.
And the biggest problem with it was all that
sitting.. I had a Jeep in the driveway and
it ran fine.. I got a new Jeep so it just sat for
a month or so.. I fired it up and the alt was
locked up.. I hit it with WD40 and in moments
it freed up.. just sitting kills them
