Powermaster 8-7228 CS121 Pro Series 100 Amp Kit, 3-Groove, XS

This kit mounts the alternator to the passenger side cylinder head area and drives off the front of the water pump with a 3-groove serpentine pulley system. This setup does not interfere with other belt drive systems already in use. The XS Volt alternator produces 60 amps at low RPMs and 100 amps at racing speed.

Available in Delco CS and Denso style alternators, these units offer a number of features including digital control, response time in milliseconds, compared to seconds for analog regulators, adjustable voltage, adjustable between 13.5 and 18.5 volts and great for 12 volt or 16 volt systems. Also features powerful, reliable internals with short circuit protection and loss of ground protection in a sealed, vibration resistant housing. One wire operation is easy to connect and turns on and off with the engine. The XS Volt gives the user a great deal of control. It also provides many benefits even without adjustment. With its digital regulator, lightning-quick response time, and the stability a digital system provides, many users have found their electronic components function better, even benefiting the daily driver.
