i saw this at Fall Carlisle and i could not resist snapping some pictures. the best the guy could tell me is it came off of some detroit engine that they scrapped. i am sure someone has seen them and worked on them but this is the first time i have seen a factory turbo blowing into a supercharger stock. i know this comes up every now and then if it is possible so i thought i would share. might be a little tall to fit under our hoods though
