Vortech v-2 sc supercharger. First let me say I KNOW NOTHING ABOUT THESE. i dont no what it came off of how old or anyother question you can ask lol i found it on the plate thats how im selling it if you dont want the plate and pullys etc i can take it off it will probably save ya on shipping but we will cross that bridge when it sell. I am selling this as is you judge condition for yourself. The supercharger itself looks to be in good shape. The one pulley on the back has some small bends in it i dont how easily replaced it is im just disclosing that its there.  If u need me to measure something i have no problem doing that or sending more pics but

Other then that i wont be much help, HAPPY BIDDING!!
