The Dodge Challenger holds the title as the world’s fastest and most powerful production muscle car. The Dodge//SRT brand shook up the muscle car world when it launched its quarter-mile 840 horsepower monster – the 2018 Dodge Challenger SRT Demon. The one-year, limited-production SRT Demon was built as the ultimate street-legal drag racer. Although the SRT Demon might be gone, Dodge//SRT now offers two models for the 2021 model year built specifically aimed at its drag racing base.
Returning for its third year of production, the 2021 Dodge Challenger R/T Scat Pack 1320 is named for the quarter-mile distance of 1,320 feet. The Scat Pack 1320 adds exclusive drag-strip technology from the SRT Demon, but in an affordable package focused on the grassroots drag racer community.
Powered by the 6.4-liter (392 cubic-inch) HEMI V8 engine making 485 horsepower and 475 lb.-ft. of torque and mated to an 8-speed automatic transmission with class-exclusive TransBrake, the Scat Pack 1320 is capable of a quarter-mile elapsed time (ET) of 11.70 seconds @ 115 mph right off the factory floor. This makes the Scat Pack 1320 the fastest naturally aspirated, street-legal muscle car that is currently available.
The Scat Pack 1320 comes with a ton of drag-specific components and technologies. Those features include the following equipment…
- TorqueFlite 8HP70 8-speed automatic transmission
- Transbrake (locks the output shaft of the 8HP70 transmission to hold the car stationary before a standard start)
- Torque Reserve (works in conjunction with the Transbrake and Launch Control, by managing fuel flow to the cylinders and controlling spark advance or retard to balance engine RPM and torque to maximize power delivery and launch performance)
- Nexen SUR4G Drag Spec 275/40R20 street-legal drag radials
- 20-inch x 9.5-inch Low Gloss Black aluminum-forged wheels
- SRT-tuned three-mode Adaptive Damping Suspension (ADS) (tuned specifically for the Scat Pack 1320 featuring “Drag Mode” like the SRT Demon)
- Driver seat only helps reduce weight by 114 lbs.
- Passenger seat and rear seat available individually for $1 each
- Performance-tuned asymmetrical limited-slip differential with 3.09 final drive
- Extreme-duty 41-spline rear axle half shafts adopted from the Challenger SRT Demon
- Line Lock (engages the front brakes to hold the vehicle stationary, but leaves the rear wheels free for a burnout to heat up and clean the rear tires)
- Launch Assist (uses wheel speed sensors to watch for driveline-damaging wheel hop at launch and, in milliseconds, modifies the engine torque to regain full grip)
- Launch Control (controls tire slip during straight-line acceleration
- Brembo High-performance Brake Package with four-piston calipers
Don’t believe that the R/T Scat Pack 1320 is a great package? We bought one back in 2019 and took it frequently to our local track. While the naturally-aspirated 6.4-liter HEMI V8 had no problem shuffling us down the quarter-mile, there are some diehard racers who will want more. Enter the much more powerful and much more expensive 2021 Dodge Challenger SRT Super Stock.
For those looking for the ultimate thrill down the quarter-mile in 2021, the 2021 Dodge Challenger SRT Super Stock is the closest thing you can get into to experience an SRT Demon. Powered by the same supercharged 6.2-liter high-output HEMI V8 as the SRT Demon, it features a revised powertrain calibration that rates horsepower at 807 horsepower on 91 octane unleaded fuel (808 horsepower on SRT Demon). Unlike the SRT Demon, the SRT Super Stock does not feature a high-octane mode to achieve 840 horsepower.
With 10 additional horsepower over the standard SRT Hellcat Redeye Widebody, in combination with the SRT Demon’s larger, sticker, NITTO drag radials, allow the Challenger SRT Super Stock to run 0 to 60 mph in 3.25 seconds and the quarter-mile with an ET of 10.5 seconds, making it the world’s quickest and most powerful muscle car currently on the market.
To make this the world’s newest ultimate drag-racing muscle car, the Challenger SRT Super Stock features:
- TorqueFlite 8HP90 8-speed automatic transmission
- Widebody Package
- SRT-tuned three-mode Bilstein Adaptive Damping Suspension (ADS) (tuned specifically for the SRT Super Stock and does not feature a “Drag Mode” but “Track Mode”)
- No Transbrake (unlike the SRT Demon, there is no Transbrake on this model)
- Brembo High-performance Brake Package with four-piston calipers
- Performance-tuned asymmetrical limited-slip differential with 3.09 final drive
- Extreme-duty 41-spline rear axle half shafts adopted from the Challenger SRT Demon
- Line Lock
- Launch Assist
- Launch Control
- SRT Power Chiller™ (liquid-to-air intercooler chiller system is activated and redirects air conditioning refrigerant to chill the intercooler coolant)
- 18-inch x 11-inch Low Gloss Granite aluminum-forged wheels
- NITTO NT05R 315/40R18 street-legal drag radials
So if you are the grassroots drag racer and are looking for the best package to start building a street-legal quarter-mile car with, Dodge//SRT has two great packages for you. The R/T Scat Pack 1320 is for those who are budget-minded or are looking to have fun on a weekend at their local drag strip, while the SRT Super Stock is focused more on the serious and experienced drivers who are looking to hone in on their skills.
The 2021 Dodge Challenger R/T Scat Pack 1320 is priced under $50,000 in the U.S. marketplace. Making it one of the most affordable drag racing packages available from the factory. The 2021 Dodge Challenger SRT Super Stock, on the other hand, borders right about the $80,000 mark.
The SRT Super Stock was available as a very limited run for the 2020 model year, those who are looking into both cars and are willing to jump into a 2020 model already on dealer lots can take advantage of Dodge’s Power Dollar campaign saving $10 per horsepower on both models. That is $4,850 off on a Challenger R/T Scat Pack 1320 and $8,070 on Challenger SRT Super Stock models.
