Its true, i was on jimmys message board and he mentioned it cost it around 17k for the kit. At first i didn't belive him, until i visited the DINAN webpage. It says ~12k for the supercharger with a * beside it. the * means to have the supercharger installed you are required to but other upgrades as well such as software chips, cold air intake ets.. and i have always noticed you always take the opposite side of people that flame the new 7 series and Chris Bangie. Well i guess everone else is wrong except you??. The new 7 is a DODGE and will never have the sport looks of a e38.
