Showing approximately 47,830 miles, this Challenger has been comprehensively upgraded with a Whipple Gen 6 3.0L supercharger and a forged internal engine build, transforming the already potent 6.4L HEMI into a serious high-performance machine. Finished in Triple Nickel Clearcoat over a Black and Red Scat Pack Logo Houndstooth interior, this six-speed manual muscle car combines factory styling with an extensive list of performance enhancements for an unforgettable driving experience.
Exterior and Interior
The exterior of this 2021 Dodge Challenger R/T Scat Pack is finished in Triple Nickel Clearcoat, giving the modern muscle car a clean, aggressive appearance. Exterior upgrades include a Redeye carbon fiber rear spoiler, an aftermarket front splitter, an aftermarket rear diffuser, and a billet aluminum fuel filler door, all of which enhance both the styling and performance-inspired character of the car. The result is a purposeful build that stands apart while retaining the unmistakable Challenger silhouette. The interior of this 2021 Dodge Challenger R/T Scat Pack features Black and Red Scat Pack Logo Houndstooth seating that complements the car's muscular personality. A rear seat delete emphasizes the vehicle's performance focus, while a harness bar and 4-point racing harness provide additional driver security for spirited driving or track use. The factory Tremec 6-speed manual transmission is further enhanced with a skip shift delete, allowing for uninterrupted gear changes and a more engaging driving experience.
Engine
Under the hood is a heavily modified 6.4L HEMI V8 fitted with a Whipple Gen 6 3.0L supercharger and upgraded with forged connecting rods, forged pistons, a Melling high-flow oil pump, Injector Dynamics ID1050x fuel injectors, a Fore dual fuel pump system, and a 112mm throttle body. The engine is tuned to run on E85 flex fuel and includes dual engine tunes, delivering exceptional performance while maintaining versatility. Power is sent to the rear wheels through a Tremec 6-speed manual transmission, while rear upper control arms improve suspension geometry and PowerStop Z23 slotted rotors with ceramic brake pads provide confident braking performance to match the car's impressive power output.
Inspection
An 8.3-liter V10, a six-speed manual transmission, and absolutely no shortage of attitude. When Dodge introduced the third-generation Viper in 2003, it took the already outrageous formula of America's most uncompromising sports car and pushed it even further, delivering sharper styling, increased displacement, and an impressive 500 horsepower. For 2004, Dodge introduced the exclusive Mamba Edition, adding distinctive interior appointments and limited-production appeal to the formidable SRT-10 Roadster. This 2004 Dodge Viper SRT-10 Mamba Edition Roadster, showing 40,322 miles, is identified as #135 of just 200 Mamba Editions produced. Finished in Viper Black with a contrasting Black and Red leather interior, this example features the Mamba's distinctive embroidered seats, red stitching, and serialized door sill plaque. Its aggressive styling is complemented by polished staggered wheels, red Brembo brake calipers, and the Viper's signature side-exit exhaust system. With its naturally aspirated V10, traditional six-speed manual gearbox, and exclusive Mamba Edition appointments, this Viper offers a particularly distinctive opportunity to experience one of the rawest American performance cars of the modern era.
