Street Rod One wire GM alternator vs. Billet-Tech / MechMan dyno showdown comparison!!

We give a sneak peak of our new alternator trade show display. It does a direct head-to-head comparison in alternator charging voltage and amperage with real-world electrical loads like Air conditioning, cooling fans, stereo, etc... We have a popular brand high output 150 amp Delco CS130 based alternator on the left, and our 6 phase Billet-Tech 170 amp unit on the right side. This display simulates a small block Chevrolet V8 with a 5.5“ crankshaft pulley running at 725 rpm engine idle speed!
