Sorry. I didn't make myself clear. I meant two different belts. One for alternator, water and steering pumps and another one just for the compressor. Why not use just one belt? This is the right question.
Well,at the time I had my supercharger installed,I had "V" belts (2) one for the alternator,& the other was for the power steering pump & water pump.
Then, one serpentine belt for the supercharger.
One belt would work w/the supercharger I had when using a serpentine belt,,,,,but if you are going to use one of the newer gear driven high boost superchargers, you would need to use a dedicated (one) belt drive for the supercharger.
