[QUOTE="SCGallo2, post: 16933306, member: 160791"] Ford OEM 2007-2014 GT500 replacement alternators are all rebuilt units at this point, and their quality and reliability are very suspect. A "new" Ford OEM replacement alternator could have cost me an engine. At idle and cruise, voltage was fine. At WOT, the alternator quit charging (think fuel pump voltage). I could see voltage drop and AFR lean out. IMO, you really need to monitor voltage and/or datalog. Read this thread: [URL="https://www.svtperformance.com/threads/how-well-is-your-alternator-performing.1159061/"]How well is your alternator performing?[/URL] I suggest looking to the high performance aftermarket: PA Performance, Mechman, Nations.
