Stock 1970 Dodge Chargers are bad to the bone, especially when equipped with the 425 HP 426 Hemi V8.   But a custom 1600+ HP 9 liter twin-turbo version sporting custom Carbon Fiber pieces and trick suspension is a whole different ball game!    The crew at SpeedKore brought TANTRUM to life, and we were afforded the opportunity to chat with designer Sean Smith about this amazing modernized Muscle Car at the 2015 SEMA show in the JET Performance display.
