Let's debunk an internet myth here and now. The '05-'08 GT Motorcraft alternator is NOT a single phase unit. It's a three phase unit just like every other automotive alternator on the planet.
It sounds like you need to upgrade yours to a higher output unit. Therefore I suggest you go to the Department of Boost website and look at the upgraded Denso units they have on offer.
