How long of a belt would I need for a P600B kit. This is a 12 rib setup. I might have this unit sold. I thought I would be nice and get this guy a belt. Also if anyone has an installation guide or now where I can get one hook me up. I don't know what happened to the one I had.
This is for a P600B kit for an LT1

 

The belt length would depend on the pulley sizes. It could be 40", 41", 42" or 43" in length. Last time I checked with Procharger concerning a manual (I was in the same situation as you...sold the kit, but couldn't find the instructions), they told me to have the new owner call and provide them with the serial number and new owner's information so they could update their records and that they would probably send him one at no charge.

 

depends on the size of the pullys, my 8 rib 9 lb pullys take a 080415 belt, my 12 rib 15 lb pully set up takes a 120400, if you can use the 400 lenght you can get them from napa, other than that its a procharger item.
