i am going to buy the procharger H.O system for my 2009 hemi R/T challenger. the car only has 3,100 miles. this project is going to cost me around $7,000. do any of you guys have and advice, like the pros & cons of doing this project. the guys at procharger tell me the H.O system is for a un-modified engine. do you guys think this is the blower to go with? thanks!
