The power-to-weight ratio of the SRT Demon is 418 hp (312 kW; 424 PS) per ton on 91 octane gasoline and 435 hp (324 kW; 441 PS) per ton on 100 octane or higher.
It reaches 0–30 mph (0–48 km/h) in 1.0 second, 0–60 mph (0–97 km/h) in 2.3 seconds (2.0s with a rollout), 0–100 mph (0–161 km/h) in 5.1 seconds, and the quarter mile (400 m) in only 9.65 seconds at 140.09 mph (225.45 km/h). This makes the Demon the fastest non-electric production car to reach 0-60 mph (0–100 km/h) and to complete a straight-line quarter mile at its time of announcement. The SRT Demon is also capable of accelerating at 1.8 G's of force at launch, making this the hardest launching production car ever. The Demon can also push the boost to 14.5 psi and redline up to 6500 rpm. With this extreme power, and hard accelerating, the SRT Demon is the first production car to ever perform a wheelie.
Because of the time the car made in the quarter mile and the lack of an NHRA certified roll cage, the NHRA banned the vehicle from competition.
