Powermaster carries high-output Mopar alternators in chrome, black, and natural finishes.
Does your Mopar's headlights go dim when you're idling at a traffic light? Did you just install a new sound system and there isn't enough power available to handle it? That was precisely the problem we were dealing with when it came to our Project D150 Dodge Truck.
Powermaster Motorsports has the answer with their high-output alternators. Powermaster uses the original Mopar housing, so you can maintain the OEM look, but when it comes to what's inside, there are many differences. In order to obtain a higher amp output, Powermaster beefs up the windings around the stator. By using a thicker gauge wire, they are able to achieve a higher idle-speed output than the stock alternator. By increasing the quantity of windings, they achieve higher highway speed amperage output.
To prove the Powermaster alternator's capabilities, we bench tested our stock Mopar alternator as well as the upgraded Powermaster unit. The original alternator showed an output of 23 amps at idle and 54 amps at highway speed. The Powermaster alternator produced a whopping 55 amps at idle and 88 amps at highway speed.
Powermaster didn't stop there; they also improved the alternator by installing a heavy-duty bearing. For race applications, they also have a black bake-a-lite-finish alternator that helps dissipate heat. All alternators come with a proof of performance card and a dyno output chart to help determine the proper pulley size.

In order to make sure the alternator works properly, it is wise to check all wire connections involved. We checked the cable going from the battery to the starter and the starter to the alternator. We also checked the voltage regulator where we added a star washer between the firewall and regulator to create a better ground.

If Powermaster's high output Mopar alternator doesn't supply enough power for your needs, they also manufacture single-wire, GM-style, high-output versions. These alternators are available with up to 225 amps of output at highway speeds and 125 amps at idle. Powermaster has these available in chrome, black, polished, and natural finishes.
