Challenger SRT Hellcat Redeye gets possessed by the ‘Demon’


  • Challenger SRT Hellcat Redeye gets possessed by the ‘Demon’

July 9, 2018 - Designed and engineered with more power to appeal to an even broader muscle car enthusiast audience, the heart of the new 2019 Dodge Challenger SRT Hellcat Redeye comes from its limited-production big brother – the Dodge Challenger SRT Demon. The supercharged 6.2-liter HEMI high-output V-8 engine is rated at 797 horsepower and 707 lb.-ft. of torque and is mated to a TorqueFlite 8HP90 eight-speed automatic transmission.

Like its Demon brethren, it has 25 major component upgrades, including a larger supercharger, strengthened connecting rods and pistons, high-speed valve train, fuel injection system and improved lubrication system.

Compared with the standard SRT Hellcat engine, the Redeye’s supercharged high-output engine features:

  • Largest factory supercharger of any production car – 2.7 liters versus 2.4 liters
  • Increased boost pressure: 14.5 psi versus 11.6 psi
  • Higher rpm limit: 6,500 rpm versus 6,200 rpm
  • Fuel: Two dual-stage fuel pumps versus one
    • At full throttle, the Dodge Challenger SRT Hellcat Redeye’s high-output engine consumes 1.43 gal/min (5.4 liters/min) of fuel—enough to drain the fuel tank in just under 11 minutes, yet is still rated at 22 miles per gallon (mpg) when driven in normal highway conditions
  • Larger induction air box with three sources of intake air:
    • New dual-snorkel hood
    • Driver-side Air Catcher headlamp
    • Inlet near the wheel liner

Additional features from the SRT Demon that help the Challenger SRT Hellcat Redeye achieve its status as the most powerful, quickest and fastest muscle car:

  • Torque Reserve delivers up to 3.9 psi of boost at launch and up to 55 percent more engine torque
  • Only factory production car with both SRT Power Chiller and After-Run Chiller
  • High-strength steel prop shafts provide a 15 percent increase in torque capacity
  • 41-spline half shafts provide a 20 percent increase in torque capacity

New for 2019, SRT Hellcat Redeye offers two final drive ratios, a standard 2.62:1 or available 3.09:1 for enhanced launch capability.

The 2019 Challenger SRT Hellcat lineup delivers improved performance numbers, including a new top speed of 203 miles per hours (mph), making the Challenger SRT Hellcat Redeye the most powerful, quickest and fastest muscle car.

Beating the heat
Heat is the enemy of any high-performance powertrain, so Dodge SRT engineers looked for more ways to keep the intake air as close to the optimum temperature as possible.

One key to the engine’s imposing power output is air—and plenty of it. The new, low-restriction, dual snorkel hood is fully functional and sealed to the air box.

When combined with the Air Catcher headlamp and an inlet near the wheel liner, these three sources give the SRT Hellcat Redeye’s high-output engine an 18 percent greater air-flow rate than last year’s SRT Hellcat engine (1,134 cubic feet per minute). At full power, this is the equivalent flow rate to 89 adults simultaneously emptying their lungs in 1 second.

The revised air inlet path on the new dual snorkel hood results in an intake air temperature reduction of 4 degrees Fahrenheit.

The innovative, award-winning SRT Power Chiller, standard on the Challenger SRT Hellcat Redeye only, diverts the air-conditioning refrigerant from the interior cabin to a chiller unit mounted by the low-temperature circuit coolant pump. Charge air coolant, after being cooled by ambient air passing through a low-temperature radiator at the front of the vehicle, flows through the chiller unit, where it is further cooled. The chilled coolant then flows to the heat exchangers in the supercharger.

The SRT Power Chiller lowers the intake air temperature further on the Challenger SRT Hellcat Redeye, resulting in improved performance.

The After-Run Chiller, also an industry first, minimizes any heat soak effects, allowing the engine to stay in optimum operating temperature. When the engine shuts down, the After-Run Chiller, now standard across the Challenger SRT Hellcat model lineup in 2019, keeps the engine’s cooling fan and low-temperature circuit coolant pump running to lower the supercharger/charge air cooler temperature. The driver can track the supercharger coolant temperature on the SRT Performance Pages in the 8.4-inch Uconnect touchscreen and know in real time when the supercharger is at the optimum temperature for another run.
