- How to Install a PA Performance Alternator on Your 2005-2008 GT Mustang
Hey, Stephanie here breaking down the PA-Performance High Output Alternator for 2005-2008 Mustang GTs. PA-Performance is widely know for their high performance charging and starting systems. They have specialized in high output alternators for the Mustang for nearly a decade. And all of their units are 100% brand new and fully tested during production, unlike some other alternator options that are out there.Now this is a 200 amp 6G series alternator that comes complete with an internal voltage regulator and a pulley that allows you to reuse your factory belt. Although, I would recommend replacing your belt while you're in the area, since you're going to be replacing your alternator anyway. This is a direct replacement that increases the charging capacity at all rpm ranges without any modification necessary. Providing 100 amps of idle and 200 amps at max.Now I will say because this unit provides higher than stock output, you will need to upgrade your main power wire. This is because the stock OE power wire was not designed to handle the increase load that this high amp alternator provides. Luckily PA-Performance offers this upgrade and it's available in the drop-down menu on the product page. If you're not already there just click the link below and see what I'm talking about.For installation you can expect to spend about two hours tackling the job with the use of basic hand tools. Now because this is a direct replacement you do not have to modify the mounting bracket. But like I mentioned before, I would recommend installing a new belt while you're installing your new alternator.And if you have any questions about the install or the alternator, you can always reach out to a Mustang expert by phone or email at anytime. So if your alternator has failed or is on its way out, then be sure to check out this high output 100% brand new replacement from PA-Performance offered here at AmericanMuscle.com.

Alternator is pretty easy to replace on a 05-09 GT... This fit perfectly and works perfectly. No complaints. (however, look for my review on the upgraded power cable, that's a bit more complicated)Helpful (0)

Bad voltage regulator brand new
We swapped alternator and cable, and voltage regulator was bad. I was really looking forward to this, but after the money and wait, had to swap again with one from autozone after losing 120 bucks at shopdetermining voltage regulator in brand new alternator bad and was spiking the electronics. So out another 120, plus another later actor, and now shipping back for.a refund, but still put an extra 120. It should work brand new out of box. UnacceptableHelpful (0)

I recently upgraded my stereo/sound system in my mustang and I felt that the system would drain my battery and that the OEM alternator wouldn't give me the power I required/wanted. I ordered this alternator and the required wire (thicker gauged) and the install was a breeze. I can't say I notice a difference but I know I have a top end high quality alternator and battery to supply my energy needs.....Helpful (1)

Car systems failure due to failing alternator after adding new 350Watt speakers in my 2005 Mustang GT 4.6 3V as well as new high output coil packs. To much for the old alternator to keep up with so bought a high output 200 amp alternator and solved all my issues! Thanks AMHelpful (0)

Check Charging System problem
Happy to say after 3 starts and 40 miles no more "Check Charging System" so far. Easy install (Removed throttle body and cleaned which made it much easier). Only complaint is with the wire upgrade. Battery side of cable is 3 to 4 inches too short. To mount as normal the inline fuse box interfered with stock negative battery connection. Had to run to the left and in front of battery. Will rectify with longer 4 ga. soon to mount as it should be mounted. Not a big problem but shouldn't have happened with a $50.00 custom part. Overall happy that Baby is running smooth again. It is still early but I am totally satisfied so far. Coming back for more goodies soon.Helpful (0)

Great alternator upgrade
After problems with OEM alternators the PA 200 Amp and cable really upgraded performance. Easy install and fixed my cold start problems. General runnability is much better too. My Bullitt has FFRP intake, hot rod cams, cam phase limiters, Steeda UDP's, stage 3 clutch, light racing flywheel, Kooks long tubes and WeaponX COPs.Helpful (1)

What type of pulley does this alternator have - clutch or clutchless?
ThePA Performance High Output Alternator will have a clutchless pulley.
What diameter is the pulley on this alternator?
I have a Paxton Novi 2200 SL supercharger and I am having problems with my alternator as it is not powerful enough to run all the extra electronics that come with the supercharger. Would upgrading to this alternator be a good choice to help give the car more power?
What is the difference between 130 amp and 200 amp? How would i choose for my 05 mustang GT?
The difference is the amperage. You will need to select the one you need for the power that you need.
Been having problems last month or so coming to stop with the motor bogging down while running the air (07 GT). Now battery not charging and Alternator showing pegged AMP gage to the Max. Time for a new alternator. Will the 200AMP help with the bogging problem? Running with power pully's too.
It is not recommended to run the PA Performance High Output Alternator with underdrive pulleys as this will void PA Performance's warranty.
You would be able to use a 175 amp battery disconnect with the PA Performance High Output Alternator - 200 Amp.
The PA Performance Alternator is a direct replacement with no mounting bracket modifications required or additional wiring.
Hey Fancy, Unfortunately this alternator will not fit your 09 GT/CS. For 2009-2010 mustangs Ford had produced a different alternator for with separate mounting as well as functionality
