Dodge Charger Hellcat makes 1,032 hp with Hennessey help

Sometimes you just want four doors. Earlier this week we brought you Hennessey's riff on the Dodge Challenger Hellcat. Now comes the Charger. Much like its two-door sibling, the Charger gets boosted to as much as 1,032 hp and 987 lb-ft of torque (at the crank) thanks to the addition of a twin-turbocharging setup that works with the factory supercharger. The turbo headers and downpipes are stainless steel, and there is a high-flow air-to-water intercooler and dual-turbo waste gates. Hennessey also beefs up the fuel injectors, fuel pump, and the rest of the fuel system. The engine management system and chassis are recalibrated to accommodate all of this. You also get numbered plaques signed by John Hennessey, the boss of the Texas tuning outfit, and the technician who does your build. Hennessey's additions result in zero-to-60 mph sprints in 2.7 seconds, and the big sedan can run the quarter mile in 9.9 seconds at 142 mph. Like the Challenger, the Charger has the same disclaimer: the lofty horsepower figure comes from an engine dyno, and it will be a 15-to 20-percent lower at the rear wheels.

Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point.
