It was only a week ago that John Hennessey ran a blistering quarter-mile in his 2018 Dodge Demon. In stock form, Dodge says the Demon is capable of running the 1,320' in 9.65 seconds. If you consider this slow, Hennessey will donate your stock 2.7-liter supercharger to charity, and install their monster 4.5-liter blower. It allowed their HPE1000 Demon to reach the top end in only 9.38 seconds at 146 mph. If this makes you sad because you are barely into the 11-second range, I feel your pain. The team at Hennessey Performance is never satisfied, so yesterday they uploaded new footage from their test & tune sessions. [soliloquy id="131474"] The quest for an 8-second time slip is a worthwhile effort, although it is more expensive than many bad habits. Chipping their way through the 9's, this blistering pass will show you just how capable the HPE1000 truly is. A quick look at the 60-foot time shows tire shake at launch. You have to remember that this car has independent rear suspension, so traction is the issue. Even so, this is incredibly impressive, so congratulations gentlemen, you've earned it.
