Sales Description
This C7 Chevrolet Corvette Grand Sport is far more than a striking black-on-black sports car. It is a professionally built, forged-engine, supercharged performance machine that combines serious power with the refinement, comfort and reliability expected from a modern Corvette.
The build was completed by Vengeance Racing with the goal of creating a Corvette capable of performing flawlessly whenever called upon while retaining the street manners and dependability of the factory platform. Rather than simply adding boost to a stock engine, this Grand Sport received a carefully selected combination of proven components designed to support substantial power.
At the center of the build is an East Coast Supercharging NOVI 1500 centrifugal supercharger system. The LT1 was strengthened with a Vengeance Racing drop-in forged piston and connecting rod package and upgraded with a Vengeance Racing Stage III camshaft kit. Additional engine-bay upgrades include Vengeance Racing raised-letter valve covers, a Mighty Mouse Solutions "Wild" catch-can system, a large electronic throttle body and custom supercharger plumbing.
The engine compartment also features a custom-painted intake manifold cover with detailed skeletal-style artwork, giving the build a distinctive presentation that matches its performance. An upgraded aluminum radiator and high-performance electric fan and shroud assembly help manage temperatures during street use and hard driving.
The fuel system was upgraded to support the supercharged combination with a GM LT4 high-pressure fuel pump, LT4 injectors and a DSX Tuning auxiliary fuel pump. A Vengeance Racing Flex Fuel kit allows the car to take advantage of ethanol-blended fuel when properly tuned, further enhancing the versatility of the package.
Exhaust flow is handled by Kooks 2-inch long-tube headers feeding a 3-inch X-pipe. The system exits through four black Corsa Performance exhaust tips, producing the aggressive tone expected from a cammed and supercharged LT1.
Power is delivered through the Corvette's 8-speed automatic transmission, which received a Pure Transmission build or upgrade in August 2023. A Circle D Specialties triple-disc torque converter complements the camshaft and supercharger combination, helping the drivetrain put the engine's power to effective use.
No horsepower figure is being represented without supporting dyno documentation, but the caliber of the components makes it clear that this is not a typical bolt-on Corvette. It is a purpose-built street and performance package assembled with premium hardware from some of the most respected names in the Corvette aftermarket.
Visually, the car is equally impressive. Its gloss-black Grand Sport widebody is enhanced by an extended front splitter, front canards, aggressive side skirts, rear-quarter aerodynamic extensions and a large rear spoiler. Black Forgestar multi-spoke wheels continue the monochromatic theme, while red brake calipers and slotted rotors add a sharp contrast.
Paint protection film has been installed on the front bumper, front fenders, hood and removable targa top to help protect the most vulnerable surfaces from rock chips and road debris. The Corvette was also fully paint corrected and ceramic coated by Glasslife Atlanta, giving the black finish exceptional depth and gloss while making it easier to maintain.
Inside, the Grand Sport retains the comfort and convenience expected from a modern Corvette. The cabin includes a custom carbon-fiber and perforated-leather steering wheel with a red center stripe, carbon-fiber trim, red seat belts, supportive sport seats, factory infotainment and dual-zone climate control. The factory air-conditioning remains installed and operational.
The underside presents well and highlights the Corvette's aluminum chassis construction, independent suspension, rear-mounted transaxle and upgraded exhaust system. The overall build is cohesive, professionally executed and designed to deliver an exhilarating driving experience without sacrificing the usability that makes the C7 platform so desirable.
For the enthusiast seeking a Corvette Grand Sport with forged internals, serious forced induction, a built drivetrain and standout presentation, this professionally modified example offers an exceptional combination of power, beauty and street-friendly performance.
