So I currently have a M90 Roush supercharger on my 2006 Mustang Gt. I was wondering if anyone would be interested in buying the complete kit or trading it for there stock manifold so I can go back to stock plus cash on your end. The M90 Is for automatic s197 and I believe its them old generation m90. This kit is not for someone who wants to make crazy power just someone who wants decent power. I had my car tuned with it and i made 363hp with stock pulley.
