Hey what size is the stock pulley on the P-1SC, I always called it a 9lb. pulley. I would like to get a 12lb pulley and put on there which is the next smaller size from the 9lb. Hey "Blue" how are you enjoying your ol Procharger, glad to see another GA. boy on the same boat as me, who you getting to do your tuning.

 

So far so good. It runs strong now. Tuning was done by Nelson. Sorry, I don't know what the pulley size is stock on the p1 compressor, give procharger a call and they should be able to tell ya.
