I have a 2002 saleen s281 s/c. Its my first mustang it had 9000 miles on it when i purchased it. It now has 35,000 and is all stock. It has a series II supercharger and intercooler, cold air intake and 3.27:1 gears. Can anyone offer some mod advice. Would like to get 400 rwhp is this possible with the series II blower?
