Mine puts out all and more than I need. I rod check it and the alternator turns on. I have a cassette player with two speakers. No amp, no sub. An electric pusher fan, and HID headlights with ballasts. Thats pretty much it. I dunno about SBM, but my BB looks like it belongs there. Mine looks like that CS130D you posted, but its just a 10si. Summit Special, generic replacement. I also do not know about the double V belt
