Dodge Unveils Challenger SRT Super Stock

Jul 31, 2020

Dodge SRT is doubling down on its commitment to drag racing with the introduction of the new 2020 Dodge Challenger SRT Super Stock.

“I swore that we’d never build another Demon and we won’t,” said Tim Kuniskis, Global Head of Alfa Romeo and Head of Passenger Cars – Dodge, SRT, Chrysler and FIAT, FCA – North America. “But I also said that every Challenger Hellcat and Redeye comes with an unspoken commitment to uphold the brand and the new Challenger SRT Super Stock is engineered to do just that.”

The drag-racing spirit of the limited-production 2018 Dodge Challenger SRT Demon lives on through the 2020 Challenger SRT Super Stock, which is powered by the same supercharged 6.2-liter HEMI high-output V-8 engine that also currently powers the Challenger SRT Hellcat Redeye, paired with the TorqueFlite 8HP90 eight-speed automatic transmission.

Featuring a revised powertrain calibration that increases the shift point from 6,300 rpm to 6,400 rpm, the Challenger SRT Super Stock delivers a power output of 807 horsepower on pump gas, a 10-horsepower boost over the standard SRT Hellcat Redeye, and 707 lb.-ft. of torque.

In addition to the new powertrain calibration, the Challenger SRT Super Stock is built on a standard Widebody and features a new suspension, standard Brembo brakes, and a wheel and drag radial combination designed to give customers better hook off the line, Dodge says.

Standard SRT Super Stock features include:

  • Lightweight 18-inch-by-11-inch wheels in Low Gloss Granite finish, riding on sticky 315/40R18 Nitto NT05R drag radials at all four corners
  • Lightweight all-aluminum Brembo four-piston brake calipers and 14.2-inch vented rotors
  • Performance-tuned asymmetrical limited-slip differential with a 3.09 final drive ratio

The SRT Super Stock clocked 0-60 mph acceleration time of 3.25 seconds and quarter-mile elapsed time of 10.5 seconds at 131 mph. It’s tire-limited top speed is 168 mph.

The SRT Super Stock comes equipped with 18-inch-by-11-inch wheels with a Low Gloss Granite finish, riding on 315/40R18 Nitto NT05R drag radials at all four corners.

The Dodge Challenger SRT Super Stock offers drivers the ability to set up for maximum drag strip performance with a variety of drive mode settings.
The Challenger SRT Super Stock is outfitted with a tuned Bilstein high-performance Adaptive Damping Suspension (ADS), which helps to shift as much weight as possible to the rear tires at launch for maximum traction.

The drive mode settings on the Challenger SRT Super Stock include Auto (Street) mode, which sets the Bilstein ADS for comfortable ride with compliant handling, Sport mode, Track mode and Custom mode, which lets the driver select between Auto, Sport and Track mode configurations for the transmission, paddle shifters, traction, suspension and steering.

When Track mode is activated on the Challenger SRT Super Stock, the front Bilstein shocks are set for firm compression and soft rebound damping, while the rear Bilstein shocks are set for firm compression and firm rebound damping. That configuration is maintained as long as the car runs at wide open throttle. When the driver backs off the gas pedal, the system switches to soft compression and firm rebound, front and rear, for improved handling.

During Track mode, the traction control system is disabled to enable the rear wheels to spin for a burnout, but the electronic stability control system remains engaged to help the driver with straight-line performance.

Track mode options:

  • TorqueFlite eight-speed transmission runs a calibration optimized for acceleration
  • Electronic stability control is optimized for straight-line acceleration
  • Suspension calibration changes to full firm in rear and firm compression and soft rebound in front
  • Paddle shifters are turned on
  • Steering is set to Drag mode for high-speed stability
  • Cabin cooling diverted to SRT Power Chiller
  • Torque converter lockup point is raised in Drag mode

Auto (Street) mode options:

  • Engine output level is set based on which key (red or black) is in the Challenger
  • If red key is present, the power level can be set per customer preference
  • Transmission, suspension and steering default to Auto (Street) mode
  • Customers can set suspension and steering preference
  • Electronic stability control defaults to full on
  • Paddle shifters can be turned on or off per customer preference
  • Eco mode is available only in Auto mode

The Challenger SRT Super Stock features standard drag-specific components and technologies, including:

Launch Assist — Helps resolve wheel hop. Wheel speed sensors watch for signs that the tires are slipping/sticking. If hop is detected, the engine control module momentarily reduces torque to maximize traction without the driver having to lift the throttle. According to Dodge, Launch Assist reduces loads in the driveline from wheel hop by up to 20 percent

Launch Control — Holds the engine at optimal launch rpm and waits for the driver to release the brake. Launch Control then uses engine torque management to optimize wheel slip for maximum acceleration

Line Lock — Engages the front brakes to hold the Challenger stationary, but leaves the rear wheels free for a burnout to heat up and clean the rear tires. The system will also let the driver perform a controlled rolling burnout and can engage for up to 200 rear wheel revolutions

Torque Reserve — Becomes active once the engine speed passes 950 rpm. The system closes the bypass valve, “prefilling” the intake with boost, manages fuel flow to cylinders and manages spark timing to balance engine rpm and torque

Race Cooldown — Minimizes any heat soak effects, allowing the engine to stay in optimum operating temperature. When the engine shuts down, the Race Cooldown feature 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

SRT Performance Pages — Includes a real-time dyno graph, g-force heat map and more

• SRT Power Chiller — This feature diverts the air-conditioning refrigerant from the interior cabin to a chiller unit mounted by the low-temperature circuit coolant pump. Charged 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 Challenger SRT Super Stock is not limited in production.
