      Powermaster Alternator

      I had this installed along with the power cable upgrade and a new engine (by a certified mechanic) and the alternator overcharged and fried itself. The power cable connection at the alternator was melted like a candle. My advice, don't buy this overpriced alternator. The shop owner says this is the second time now that he has seen a powermaster alternator fry itself.

      Review from Powermaster Alternator - 225 Amp Chrome (99-04 GT)

      Pretty good buy

      Needed a higher amperage alternator for my mustang to supplement my new amp install. Good product, no issues. Will be replacing soon with a higher output specialty alternator.

      Works great

      Bought this from American Muscle, revived it the next day. Top notch customer service and support on this purchase. Installation was a breeze. Looks great under the hood,.

      Review from Powermaster Alternator - 225 Amp Chrome (99-04 GT)

      Great Alternator!

      The stock alternator had problems keeping up with the stereo that I have in the car. After installing this alternator, I haven't had the headlight dim at all. On top of the great performance, it really looks awesome! Really ties all the chrome items under the hood together.

      Keeps Power to Your Engine At It's Peak

      I purchased this mainly to insure that maximum amperage and power was being delivered to my ignition coil on plug packs and fuel pump at idle and under load. I also have an aftermarket stereo head unit and wanted to insure that there is no power loss to the headlamps when in use. When the alternator arrived it was well packed with injection foam packets to make sure that there was no movement during transport. The alternator also came with a proof of performance certificate what showed when the date it was tested, power reading at idle, simulated cruising rpm, and maximum rpm and maximum voltage delivery. It gave me confidence in knowing that the alternator was ready for high demand use. Install was quick and easy with basic hand tools. It took me less than 15 minutes to do the work. I previously purchased a power wire from AM to protect the electrical system and handle the increased supply load. Acceleration is much smoother and the instant of hesitation that I was previously experienced went away. I feel at a minimum that an owner should upgrade their power wire and alternator to insure that you are getting peak electrical power and performance out of your car. This alternator will be ready to handle additional mods as you build your car. You can't go wrong with this investment.

      Review from Powermaster Alternator - 225 Amp Chrome (99-04 GT)

      so far so good

      puts the power out and looks awesome under the hood. The BBK aluminum pulley did not fit however. So I had to use the super heavy pulley that came with it.

      I didn't think that adding a new alternator would make such a GREAT difference in ZIP!!!!!!!, My 1999 mustang GT is supercharged and that added juice really brings it to life a VERY noticeable improvement over the stock alternator!!!

      Easy installation (woman approved)

      Easy installation! Came quick. Better idle. (Not anything extremely noticeable but it didn't do any harm which is always a plus.)

      looks great works well

      Looks great under the hood, and preforms well. Took about a good 2 hours to install with the added and needed power cable, spliced it in with the original wiring harness so it look pretty much stock.

      No more power loss

      This product helped with power loss at idle when running air conditioning and other accessories. Take off is more smooth from a stop.only had it in for a week or two good so far.easy install exact fit no problems.

      Review from Powermaster Alternator - 225 Amp Chrome (99-04 GT)

      Worked well for short period.

      Quality of alternator worked well for about 500 miles.. it's at powermaster now currently being repaired said it was over spun. But I'm running stock pulleys, no forced induction or even cams. I have cams but not been installed yet. Said the internal fans were twisted. So for now stock alternator back on, it was bought mainly to improve my underpowered look plus the extra amperage. American Muscle did their part it just a 3 due to the issue with the defective product.
