Powermaster Street Series alternators feature all of the quality construction and dependability the company is famous for. The "electrical generators" are available in a variety of amperages and styles, allowing you to choose the best model for your specific ride and the accessories you run. So whether you need an alternator for your truck, hot rod, muscle car, sport compact, or audio competition vehicle, Powermaster gives you the power needed to get it started and keep it going. These race-inspired alternators offer great output to weight ratio. Here are more product details: For most people, the only alternator rating they're familiar with is the amperage rating. Alternators are spoken of as a 65 amp or 100 amp alternator. When replacing the alternator on the family car, this is probably the only information that's necessary. After all, all one needs is an alternator that matches the original. When building a custom car from the ground up, however, a deeper understanding of the power curve of an alternator is required. Usually a custom pulley or so-called "power pulley" set is used with a performance alternator. A mismatched pulley ratio and alternator will spell trouble, especially at idle speeds where alternator performance is critical. To avoid this, it's important to understand the alternator's capability at slow speeds. An alternator's output is dependent on speed, but this can be deceiving because this output is not linear. Instead, it follows a curve. Each alternator has a unique curve, and at idle small changes in the alternator's speed can make a big difference in its output capacity. Because of the preceding, pulley ratios are very important, especially when using high amperage alternators. The pulley that are supplied with the alternator are matched to the winding and power curve. It's important that any dress-up pulley sets do not deviate from this ratio. Typically, a street driven car should have a pulley ratio of at least 3:1. If the vehicle has an automatic transmission with a low idle and the vehicle spends a lot of time cruising, then a higher pulley ratio—perhaps 3.5:1—should be used. Alternators can take high speeds up to 20,000 rpm for short periods, so overdriving the unit is not a problem. The output of high amp alternators can drop off substantially under 2,400 rotor RPMs. Therefore, Powermaster does not recommend power pulleys with high amp alternators. Powermaster uses a state-of-the-art computer alternator dyno to measure the performance of each alternator they manufacture. Output curves, engine idle speeds, and alternator pulley ratios are carefully considered to assure good drivability at idle and slow cruising speeds.
