I have seen the curb weight of a 2005+ mustang GT (manual) listed as 3450. However I have seen considerably higher weight figures. (see R&T standing mile, 3850, with 200 lb driver) So my question is what is the right figure 3450 of 3650. By the way the vortech supercharger with aftercooler is approximately 60 pounds. Does anybosy have any accurate info on this?
