Sounds like a simple and cost effective mod, as long as the results are effective anyways.

On my car, for some reason, the voltage runs ~14.1 while I'm moving at a decent speed. At idle/lower RPMs, the voltage drops to ~13.5, with or without the amplifiers, etc on.

I'm hoping this overdrive pulley will allow for a higher/more consistent voltage output at idle/lower RPM.
