This 2018 Dodge Challenger SRT Demon is one of five Demons fully re-bodied in carbon fiber by SpeedKore Performance Group. This car was used by SpeedKore as a development vehicle to create carbon fiber components for the 2018+ Dodge Challenger Wide Body and was further built to showcase the possibilities of SpeedKore’s prepreg carbon fiber process.
First, SpeedKore produces a 3D digital model from a blue light scan of an entire Dodge Challenger Wide Body. Then, a five-axis CNC machine cuts the molds to create plugs and panels pulled using aerospace-grade prepreg carbon fiber. Prepreg is the industry term for fabric reinforcement pre-impregnated with resin, typically an epoxy. This resin is applied to the carbon fiber fabric with calibrated machinery, ensuring an exact resin-to-reinforcement ratio. The molded carbon fiber body panels are then cured using SpeedKore’s massive in-house autoclave, which applies vacuum and elevated pressures resulting in excellent fiber consolidation and composite structural performance. The result is a unique hypercar-quality carbon fiber body with perfect carbon fiber weave alignment, and in the case of this demon, a 200lbs weight reduction over the stock vehicle.
Aside from the significant modifications to the car’s body, this 2018 Dodge Challenger SRT Demon is otherwise stock. It’s 6.2 liter supercharged Hemi V8 produces 840 horsepower and 770 pound-feet of torque, but it’s far more than a Hellcat Hemi with more boost. Dodge massaged the blown 6.2 liter powerplant with 25 major component upgrades, chief among them a larger supercharger with displacement increased from 2.4 liters vs. 2.7 liters. Boost pressure is moreover increased from the Hellcat’s 11.6psi to 14.5psi, and redline increased from the Hellcat’s 6,200rpm to 6,500rpm. Further, Dodge added new, stronger pistons and rods, along with an upgraded valve train and fuel injection system.
The result is a world’s fastest production car 0-60 time of 2.1 seconds (with a 5ft rollout, or 2.3 seconds from a standing start). That number is partially afforded by the Demon’s quick-shifting ZF 8-speed automatic, fitted with the drag-race-bred TransBrake that locks the transmission output shaft to hold the car in place before a standing start. This allows for an engine speed of up to 2,350rpm without overpowering the brakes, resulting in quicker power delivery and increased torque on launch.
The Dodge Challenger SRT Demon is a limited-production street-legal drag car made even more special by its full carbon-fiber body from SpeedKore.
This car has spent most of its life visiting local car shows and is looking for a new home to make room for new projects. It has very low mileage (181 miles) and is a perfect weekend cruiser or drag strip monster.
