INTRODUCTION
This is a supplement to your Dodge Challenger Owner’s Manual. Please review the
Owner’s Manual in addition to this user’s supplement.
The 2023 Dodge SRT Demon 170 is the industry’s fastest purpose-built and street-
legal production drag car. This vehicle has been developed to be the dominating force
at the drag strip and to rewrite the boundaries of performance on the street. To
achieve this goal, all aspects of the vehicle have been re-tuned and re-engineered.
Your Dodge SRT Demon 170 is the most powerful Dodge ever, with industry-first drag
performance features that put this car in a league of its own.
Key Performance Features:
•Flex Fuel Capability: The engine is designed to run on premium gasoline and - for
maximum power output - ethanol-blended fuel. The detected ethanol percentage is
displayed in the instrument cluster and engine power is adjusted automatically.
•TransBrake™ 2.0: A second generation of TransBrake™ that allows the driver to
configure and select from multiple launch torque profiles to match the engine’s
power delivery to the specific track condition.
•SRT Power Chiller: Diverts the A/C refrigerant to the supercharger for cooler air
intake temperatures to achieve maximum power output.
This supplement offers insight into unique characteristics of the vehicle, including its
special features and how they operate.
This vehicle has been designed to maximize performance at the drag strip. Especially
in standard single-seat configuration, the extensive lightweighting measures result in
increased interior noise, and drag strip use may further increase noise levels. The drag
radial tires produce more vibration than standard street tires and have limited wet-
weather capability. The default normal drive mode is designed to maximize engine
response and personality, for street and sport driving conditions. Eco mode offers
increased fuel efficiency and quieter exhaust character, as well as a more relaxed
throttle pedal recommended for wet weather conditions.
For customers who want all-weather capability on the street, Direct Connection offers a
street wheel and tire package.

ENGINE BREAK-IN RECOMMENDATIONS — 6.2L
New Vehicle Break-In
Before driving your vehicle, remove the yellow front splitter protectors if the dealer has
not already done so. These are designed only for protection during shipping; failure to
remove could cause unexpected damage to other motorists if they come loose unex-
pectedly. The protectors will trap dirt and debris which could scratch the splitter.
It is imperative that the following break-in schedule be followed to prevent engine and
driveline damage and ensure component longevity:
0 to 100 miles (0 to 161 km):
•Do not allow the engine to operate at idle for an extended period of time.
•Press the accelerator pedal slowly and not more than a third of its travel to avoid
rapid acceleration.
•Avoid aggressive braking.
•Drive with the engine speed less than 3,500 RPM.
•Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.
100 to 300 miles (161 to 483 km):
•Press the accelerator pedal slowly and not more than halfway to avoid rapid
acceleration.
•Avoid aggressive braking.
•Vary the load, but do not exceed 4500 RPM.
•Drive with the engine speed less than 5,000 RPM.
•Maintain vehicle speed below 70 mph (112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
•Exercise the full engine RPM range by shifting manually (with shift paddles or by
moving shifter to M-gate position) at higher RPM when possible.
•Avoid aggressive launches and sustained wide-open throttle acceleration.
•Maintain vehicle speed below 85 mph (136 km/h) and observe local speed limits.
For the first 1,500 miles (2,414 km):
•Do not participate in track events, sport driving schools, or similar activities during
the first 1,500 miles (2,414 km).
NOTE:
•Check engine oil with every refueling and add if necessary.
•Oil and fuel consumption may be higher through the first oil change interval.
•Running the engine with an oil level below the add mark can cause severe engine
damage.
Even after break-in, avoid running repeatedly into the engine speed limiter at
6500 RPM in order to prevent damage.
WARNINGS AND CAUTIONS
While reading this user supplement, you will find a series of WARNINGS that must be
carefully followed to prevent incorrect use of the components of the vehicle, which
could cause accidents or injuries.
There are also CAUTIONS to prevent procedures that could damage your vehicle.

WARNING!
•If the passenger and/or rear seats have been removed do not ride in those areas.
In a collision, people riding in those areas are more likely to be seriously injured or
killed.
•Warning labels are included in the car to reinforce this point.
•If this vehicle was not factory equipped with a passenger seat, NEVER attempt to
install a passenger seat because the safety systems, including the air bags and
seatbelt, may not properly protect the occupant.
•Read and follow all instructions and warnings in the Seats and Occupant
Restraints sections of the owner’s manual for additional information.
CAUTION!
Because of the extreme conditions encountered during track use, any damage or
wear associated with track use MAY NOT be covered by warranty.
VEHICLE ALTERATIONS
WARNING!
Any modifications or alterations to this vehicle could seriously affect its road worthi-
ness and safety and may lead to a collision resulting in serious injury or death.
CAUTION!

FEATURES OVERVIEW
For more information on these unique features scan
the following QR code.
Use this QR code to access your digital
experience.
USING ETHANOL FUEL
When ethanol is detected in the fuel, a gas pump icon
will appear in the instrument cluster to indicate the
detected ethanol percentage. In the infotainment
screen's Drive Mode options page, both an icon and
"Ethanol Detected" text will appear.
NOTE:
The displayed engine power automatically changes as a
function of the detected ethanol content and repre-
sents the maximum achievable power under nominal
conditions.

NOTE:
•The threshold for ethanol detection is 5%.
•Ethanol percentages are distinguished by color.
○White — Ethanol Detected: Ethanol content is
between 5% and 64%. The power display will
indicate between 900 HP and 1024 HP accord-
ing to the detected ethanol content.
○Blue — High Ethanol Detected: Ethanol content is
65% or higher. Full power is available up to
1025 HP under nominal conditions.
•The target air to fuel ratio is a function of detected
ethanol content and driving conditions.
•Commercially available E85 fuels are typically not
exactly 85% ethanol. Ethanol content is adjusted
seasonally to ensure proper engine performance.
The engine may be difficult to start if the fuel's etha-
nol content is too high for ambient temperature.
•To maintain the necessary air to fuel ratio, addi-
tional fuel flow is required as ethanol content
increases. "Race" fuels with ethanol content above
85% will not increase engine power and are not rec-
ommended, as the necessary fuel flow may be more
than the injectors can provide. If this condition is
detected, engine performance will be reduced.
•If the vehicle will not be driven for more than a
month, it is recommended to run the engine with
premium gasoline before storage page 27.
MICKEY THOMPSON TIRES
Recommended Tire Pressure:
Street: 32 psi (220.6 kPa) cold for all tires
Drag Strip:
•ET Street R Rear Tires – depending on the outside
temperature and track conditions, the operating
pressure recommendation is 18-24 psi (124–
165kPa)hot.
•ET Street Front Runner Tires – Increase front tire
pressure to reduce rolling resistance. Do not exceed
maximum tire inflation rating.
•Tires may exceed the speed rating of 149 mph
(240 km/h) only in drag race applications and never
in highway use.
NOTE:
•Due to the design construction of the ET Street R
rear tires, some tire imbalance is to be expected
and is considered normal.
•Always return the tire pressure to street recom-
mended pressure levels before driving vehicle on
public roads.
•To help mitigate tire-to-rim slip on prepped surfaces,
Dodge recommends the use of high-tack gasket
sealant on the rim bead.
•Contact Mickey Thompson Tires at: 330-928-9092
for additional tire information.
WARNING!
Serious injury or death may result from tire failure
due to under-inflation and/or overloading. Always
adjust your tires to the proper inflation pressure (See
tire information placard). Always inspect your tires for
any signs of damage before proceeding onto public
roads or race tracks.
WARNING!
Mickey Thompson Rear Drag Radials and Front Run-
ners meet U.S. D.O.T. requirements, but they are not
intended for extended street and highway use as the
expected miles of wear from the racing compound is
greatly reduced compared to a conventional road tire.
CAUTION!
Mickey Thompson Rear Drag Radials and Front Run-
ner tires are not recommended for driving in wet
weather conditions. Drive cautiously and reduce
speeds in these conditions.

•STREET: Tuned for daily driving, shocks adapt to
road and driver input to maximize ride and handling
balance. Accelerometers on the body are utilized to
increase damping only when needed to alleviate
float. Aggressive driving is sensed using steering
wheel angle velocity, lateral and longitudinal thresh-
olds to transition the shocks into high damping. This
maximizes response and control for evasive
maneuvers.

out to achieve desired tire launch temperature. It is
recommended that the tire surface temperature after
the bunout be within 20°F (7°C) of the current track
temperature.
•If track temperature is 65°F (18°C) or lower, a lon-
ger burnout may be necessary.
•If track temperature is 120°F (49°C) or above, a
shorter burnout will suffice.
TRANSBRAKE™ 2.0 FEATURE —
TRACK USE ONLY
TransBrake™ 2.0 was designed specifically for Demon
170 to maximize drag strip performance. Like the origi-
nal TransBrake™, it engages an additional transmission
clutch to enable higher staging torque than can be held
by the vehicle brakes. TransBrake™ 2.0 debuts a new
interface and additional traction management features
to provide the most consistent launches and ease-of-
use across the range of dragstrip surface conditions.
With a new infotainment interface, TransBrake™
2.0 allows the driver to pre-program the engine's torque
delivery as a function of time-from-launch and during
1st-2nd and 2nd-3rd gear upshifts, to design a rate of
torque increase matched to the provided track condi-
tions. Torque Reserve is automatically enabled and
responsible for the unique sound of TransBrake™
2.0 operation; it reduces intake filling time and allows
more torque to be delivered more quickly than would
otherwise be possible.
The system is easier to use than ever: pre-program the
launch RPM and torque behavior, then use the steering
wheel paddles to time the perfect launch. TransBrake™
2.0 automatically delivers the desired launch torque
curve while the driver maintains full throttle.
This sophisticated set of features is intended for track
use only, where consistent quarter mile times are
desired. The system is not intended to compensate for
lack of driver experience or familiarity with the track.
Use of this feature in low traction (cold, wet, gravel, etc.)
conditions may result in excess wheel slip at launch.
TransBrake™ 2.0 Home Screen
The TransBrake 2.0 home screen can be accessed by
one of the following methods:
•Pushing the TransBrake™ button on the instrument
panel.
Instrument Panel TransBrake™ Button

TransBrake™ 2.0 Feature Overview
For the best performance, Launch Torque should be
configured to deliver maximum torque as quickly as is
possible for the track conditions. Three memory con-
figurations are provided to store a customizable set of
launch torque, shift torque, and launch RPM settings.
Select between the A, B, and C configurations by press-
ing the corresponding buttons on the home screen.
•Setting A is pre-configured for ideal, high-grip track
conditions
•Setting B, for medium grip
•Setting C, for low or no-prep
Any TransBrake 2.0 settings that are adjusted by the
driver will be automatically saved to the memory con-
figuration from which they were modified. To revert to
factory default settings, press the Reset button and
confirm when prompted by the pop-up screen.
The launch RPM can be adjusted directly on the home
screen by either dragging the speed selection bubble or
pressing the up and down arrows. Adjusting the launch
RPM will automatically save it to the currently selected
memory configuration.
The center graph on the home screen displays either
the launch or shift torque profiles, depending on the
selected tab.
Launch Torque
The Launch Torque display shows the “Pre-Stage”,
“Driver Desired”, and “Available” curves associated with
the currently selected memory configuration.
•Pre-Stage: The amount of torque required to main-
tain the selected launch RPM while the vehicle is
fully staged, just before launch.
NOTE:
Selecting an initial launch torque below this value
will cause an engine RPM reduction at the moment
of launch.
•Driver Desired: When launched, the engine will
deliver torque according to this driver-customizable
profile, as a function of time from launch.
•Available: This curve represents the maximum
torque achievable during a perfect launch with the
selected Launch RPM, detected ethanol percentage,
intake air temperature, and barometric pressure.
The initial value (at time = 0 seconds) is the fully-
staged torque, plus Torque Reserve. Setting the first
“Driver Desired” bubble at or above the “Available”
line will instantly deliver all of the available torque
reserve at launch.
NOTE:
•If all of the available torque reserve is not scheduled
to be used immediately at the moment of launch, it
remains available for a short time before being
depleted. This enables a soft initial launch followed
by aggressive torque increase strategy, useful for
limited traction situations.
•Available Torque Reserve generally increases as
Launch RPM is raised, except when limited by
engine capability. The torque delta between the
“Pre-Stage” dot and “Available” line (at 0 seconds)
reflects the available Torque Reserve.
•Engine torque naturally decays at engine speeds
higher than the peak torque RPM, in accordance
with the engine’s torque curve. This decay is not
shown in the “Available” curve, so selections below
“Available”, but above the engine’s maximum, may
not be achievable.
•The "Pre-stage" dot and "Available" curve move as
the Launch RPM is modified. The higher the launch
RPM, the more torque is available while staged
(unless Torque Reserve is limited by engine capabil-
ity), and the more quickly it grows after launch.
•Do not exceed 5 mph (9 km/h) while in “Pre-Stage”
to prevent cancellation.
Shift Torque
The Shift Torque display shows the torque reduction to
be delivered during the 1-2 and 2-3 upshifts. By
default, the upshifts are calibrated to minimize torque
loss to the wheels, which necessarily causes some
‘push’, or momentarily increased wheel speed accelera-
tion. If track conditions are suboptimal, wheelspin may
occur during the upshifts. TransBrake 2.0 Shift Torque
management exists to enable torque reduction to be
added in these conditions, to soften the shifts and pre-
vent wheelspin.
