For most people, the only alternator rating they are 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 is 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.
