This 2015 Dodge Viper GTC has just 3,400 miles. It was equipped at the factory with the Time Attack 2.0 Package – which added carbon-fiber aerodynamic elements, a fixed rear wing, and revised suspension and brake components – and its 8.4-liter V10 was retrofitted with a CMS1300 twin-turbocharging build by Calvo Motorsports of Austin, Texas, after it was acquired by its current owner on BaT in April 2023. The ~$80k project included 67mm ball bearing turbochargers, a dual-core intercooler, a Chill Out radiator, an Nth Moto clutch assembly, and a custom-fabricated exhaust system. The car is finished in Viper White Clear Coat with blue stripes over black Nappa leather upholstery, and it has a six-speed manual transmission, a limited-slip differential, electronic launch control, a rearview camera, an 18-speaker Harman Kardon sound system, and Uconnect infotainment with navigation. Registered in Texas and Georgia since new, this Viper is offered with a window sticker copy, manufacturer’s literature, two keys, 2023 service records, a clean Carfax report, and a clean Georgia title in the owner’s name.
Paint protection film is noted on the body, and exterior details include carbon-fiber front corner splitters and dive planes, a fixed rear wing, a gloss-black rear applique, HID headlights, LED taillights, side-exit exhaust outlets, and a carbon-fiber clamshell hood, double-bubble roof, and rear hatch.
Black-finished 18″ and 19″ Sidewinder II wheels were mounted under current ownership with 295/30 front and 345/30 rear Toyo Proxes R888R tires that show 2021 and 2022 production date codes. The Time Attack suspension has a revised two-mode Bilstein DampTronic system, and black-finished Brembo calipers with orange Viper lettering are fitted over StopTech 2-piece performance brake rotors at all four corners. The brake fluid was flushed in December 2022.
The bolstered Sabelt bucket seats are trimmed in black Nappa leather with white stitching, which extends to the dashboard, center console, and door panels. Additional appointments include red seat belts, satin silver trim, a power-adjustable driver’s seat, an Alcantara headliner, automatic climate control, a ParkView back-up camera, an 18-speaker Harman Kardon audio system, and Uconnect infotainment with navigation and an 8.4″ touchscreen.
The flat-bottom SRT steering wheel frames a central 7″ configurable tachometer display. The digital odometer indicates 3,400 miles, approximately 500 of which were added under current ownership.
A carbon-fiber structural X-brace spans the hand-assembled 8.4-liter V10, which drives the rear wheels through a Tremec six-speed manual transmission. The engine was retrofitted in 2023 with 67mm ball bearing turbochargers, Turbosmart billet wastegates and blow-off valves, triple high-flow Walbro fuel pumps, billet fuel rails, ID1700-XDS fuel injectors, an intercooler with two Garrett cores, and a custom-fabricated exhaust system with ceramic-coated manifolds.
Billet motor mounts, a pinned crankshaft and bearings, and an Nth Moto triple-carbon clutch assembly are also itemized in the service records for the work, which are shown further at the end of the gallery below.
