ATI Procharger P600b Supercharger System for 5.0 Mustang. System is complete just as it came from Procharger. Has the head unit, 14lb pulley, all duct work, Procharger BOV, Huge upgraded 3core intercooler, bracket for 5liter etc... Was purchased new to go from Frederick Co. Md. to OC Md. and back for Rod Run and was removed! There are LESS than 500 miles on the entire system! Performed FLAWLESSLY and got over 20MPG on the highway! Currently pullied for 14lbs but is capable of 26lbs and over 800HP! Got LOTS of attention every stop light! This is NOT your avg used junk supercharger with thousands of miles that needs rebuilt or lots of work! There are ZERO mechanical issues and it is READY TO ROCK!
