I havent installed it yet because my car isnt together yet but I did receive my new alternator today from powermax, that I ordered 3 days ago, It was $100 shipped free and setup as 3 wire. Rated at 85 amps at idle and 140 amps at 1200 rpm. All I can say is quality looks outstanding and I've seen worse from major auto parts stores. Just thought I would put this out there because I know most of us need higher amp alt due to upgrades...
