Alright well i'm interested in adding a few more ponies to my mustang and looking at superchargers not interested in prochargers i like the idea of top mounts and the looks much better. Something along the lines of this 2005 Mustang V6 X-Charger Supercharger Kit - HI-PO Plus the reason i am posting this is because i have most of these parts already, Fuel pump, intake, exhaust, fuel inject. ect. My main question here is what head unit is needed (where do i get the one from the picture) and how much work is it really to do. I do have lifetime tunes from American Muscle so im not worried about tuning but im not about to spend 4800 on a Supercharger system when all i need is a head unit. Any ideas on what head unit is used along with the spacer plate belt pully ect. (i do work for a sheetmetal company so can make spacer plate if i can get the dimensions) SUMMER TIME MEANS TIME FOR UPGRADES!
