Hi all I have a question. I bought my 2001 Lightning used, and looking at the blower pully and based on the fact that it pegs the 10psi factory gauge and is rated for 8psi stock, I think my pully was changed. I haven't measured the lower one yet, but my upper pully is about 3-1/8 " in diameter. Does anyone know what pound pully that is? I am working on getting a pod gauge to see just what I am pushing, but I remember seeing a thread talking about pully diameters, just can't find it. Any help would be appreciated.
