Callaway Cars, a well-known name in the world of automotive performance, was founded by Reeves Callaway in 1977. He established his reputation by modifying existing vehicles, enhancing their performance, and creating unique, high-performance automobiles.
One of Callaway's most celebrated projects was the Callaway Twin Turbo Corvette (RPO option B2K), introduced in 1987. This fourth project for the company marked a significant milestone. It involved the installation of a twin-turbocharger system onto the Chevrolet Corvette’s “L89” V8 engine, initially boosting horsepower from the stock 245 to a remarkable 382, while also increasing torque and overall performance. By 1991 the ZR-1 Corvette had arrived, and Callaway would raise the output of the B2K option to 403 horsepower with 575 lb-ft of torque.
The Callaway Twin Turbo Corvette quickly gained recognition for its impressive power, sleek body modifications, and improved handling. The Twin Turbo Corvette was a statement of excellence and innovation in the world of sports cars, solidifying Callaway's reputation as a premier custom builder, setting the stage for further groundbreaking ventures, and cementing Callaway Cars as a respected name in the realm of high-performance automobiles.
This car is part of the George Foreman Collection, which comprises over 50 cars from the 1930s through today, with a focus on American classics and late-model sports cars. View the full collection here.

Please note that the vehicles in The George Foreman Collection have been in long-term static storage and will benefit from additional mechanical attention prior to being driven. Bidders are encouraged to review the Additional Documents section of each lot for any recent mechanical service rendered to help return certain vehicles to running condition. Additionally, bidders should carefully review the photos of each lot in the collection, which may highlight the oxidation of metal components certain vehicles sustained as the result of a garage fire caused by a golf cart battery in March 2019. Although none of the vehicles sustained fire damage from the fire itself, the negative cosmetic effects of the corrosive soot vary greatly from vehicle to vehicle and can be observed in the photo galleries of each lot. All lots are sold as is, where is, and bidders are responsible for any desired diligence before placing a bid.

The clean CARFAX Vehicle History Report for this 1991 Callaway Twin Turbo Corvette Convertible indicates that it is a single-owner example, entering The George Foreman Collection in February 1992. The delay in delivery was likely due to Callaway’s performance modifications made in Old Lyme, Connecticut, and the 131 testing and validation miles put on the car before delivery to the selling dealer, Ground Effects of Houston, Texas. Today, this rare Corvette variant (one of just 71 produced in 1991) features a mere 6,832 miles on the odometer, an incredible relic of RADwood era tuning and design.
