Scott Spock Racing and Nelson Racing Engines are building a custom 1968 Dodge Charger called Maximus. The bodywork alone has 1,500 hours. In the trunk sits a custom fuel cell that holds two different fuels, pump gas and race fuel. The driver will be able to select which fuel via a switch. The twin-turbo 9.4 L Hemi V8 will produce 600 to 2,000 horsepower depending on the boost. The should be capable of an eight-second quarter-mile and top out at 200 mph. Extra aerodynamics are being developed to allow this car to reach a top speed of 260 mph if they can find anyone crazy enough to try. One look at the speedometer says it all.
They start discussing the engine at 13:43 in the video below.
