Powermaster also offers several low mounting bracket assemblies for small- and big-block Chevrolet engines as well as for 9in and Quick Change rear ends.
♦ Lightweight 100mm Denso-style housing weighs less than 6.5lb

XS Volt 100mm Denso for 12-16 Volt Systems
For racers running 16-volt batteries, Powermaster also offers an XS Volt version of the new 100mm alternator. The XS Volt 100mm model features a unique voltage control system that allows the voltage output to be adjusted from 13.5-18.5. This feature enables racers to run their electronics at full operating voltage, which is important for ignition systems and fuel pumps. Adjustments are made through an easily accessible potentiometer.

I have been using Denso for over 15 years. They are lighter. I use one for a small fork lift truck. It generates small amperage, so it doesn’t load the circuit, and it puts out just enough to keep the MSD working. I buy them for $110.00. When they stop working, I either replace the board, fix them if I can, or throw them away.
