Say hello to the Super Demon

The Dodge Challenger SRT Demon is widely known in the racing world as one mean machine. Factory the demon produces enough power to blast a 9 second 1/4 mile time, but why stop there? We didn't! We had the privilege of adding an insane amount of upgrades to put this Demon just shy of 1000 WHP on pump gas.

    My car was a total mess when I brought it in

    Fuel was so rich I was leaving a huge cloud of smoke out of my exhaust. Not only did he tune my car he put up with me having stipped bolts and a dead battery. This will be my first stop after getting a much needed turbo upgrade
