Many customers have asked for pulleys that don't
underdrive their alternators. Some audio competitions require that
voltage remain at factory levels. With our new 12 volt Charger Series,
the alternator s left to spin with a slight overdrive. The remaining
accessories are still underdriven (excludes accessories driven off the
same belt as the alternator) for additional power gains.
