      Great product so far

      So far so good on the alternator. I had a bad alternator and switched it out for this one and so far so good. The power is noticeable and gives the car a good 13.5 to 14.5 volts when the car is on. The only thing I would have to say is the pulley is bigger so you will definitely have to buy a bigger belt. I went with a 77.6 because it was the only one I could find in town. I might be switching to a tighter belt. I also installed the power wiring as well. So far so good with everything.

      170amp PA alternator

      Case is identical to the stock Ford 6g alternator. Internals looks beefier, but still the same cheap and problematic voltage regulator hiding inside. Larger pulley installed from PA, so expect to buy a new belt with this. I went 77.5 and my tensioner is 1-2 mm on the smaller bar from middle.

      No Problems

      Second time purchasing on my second Cobra, check you're pulley size especially if you are running a smaller super charger pulley.

      Solved my problem with with my electrical issues. Rpms on gauge cluster goes crazy if you floor the car at times. Problem solved with this new higher amp alternator.

      Works amazing

      Installed this alternator wasn't sure if it would be a worthwhile upgrade but it definitely works great no more battery light and voltage stays up no more light flicker

      It's worked

      Easy to install if you have the car off the ground. Just not very impressed with power. Still struggling to have 14v while driving. Even with a XS power battery. Only running 5 channel audison amp with 2 10in subs.

      We will see.

      So I bought this after my factory one started screwing off at 27k miles. I love the bigger pulley buuuuuuuuuuuuut it says on the site that you can use factory belt and this is not true. I had to special order a belt that was 77.2" long. That keeps the tensioner tight but not all the way to the top. It seems to be running well two days having it in. There does seem to be some flickering with the bass on my mach 1000 amp set which is strange since it didn't happen with the stock alternator. American Muscle needs to get on top of showing that it needs a different belt and that stock will not work. Otherwise happy.

      More juice means more power

      The 170 amp alternator is a great unit. What should be mentioned is that, even though the site says it isn't required, PA Performance requires the 4ga power wire upgrade for them to honor any future warranty claims. I also recommend that option as well since it raised voltage at the battery from 14.2 to 14.8 at idle. Also, the alternator came with a 3.2" pulley already installed. Saved me a few bucks!
