Vehicle or Project Description

It was the Alfa Twin Turbo car that was the catalyst that sparked interest within the ranks of General Motors (GM) towards Callaway Cars and their engineering abilities. In the early 80’s GM was looking at high performance engine options such as turbo charging and multi-valve technologies. GM was aware of Callaway’s reputation and the cars it had produced. In fact, they had taken a Callaway Alfa Twin Turbo and examined the work closely. After GM’s own twin turbo V6 and V8 projects had run their course, Dave McLellan gave the nod to Callaway, authorizing him to develop a prototype. The resulting prototype was introduced in June 1986 to GM and the media. With 345 hp and 465 lb-ft torque, the twin turbo V8 package was engineered to be the ultimate Corvette package, producing tremendous power while retaining its emissions controls and a complete warranty.

The Callaway Twin Turbo Corvette became known as Chevrolet option RPO B2K and was available through select Chevrolet dealers both in the United States and abroad. It continues to hold the distinction of being the only engine package produced outside of GM to hold an RPO code, something that will probably never happen again. Produced between 1987 and 1991, over 500 of these special Corvettes were made in coupe, convertible, and at the close of production, the Speedster form. By ordering a Corvette through the dealer, and checking the option box for B2K, it triggered a series of events, which ensured the cars received special equipment and handling under SEO Z5G.

Throughout production, changes were made. Optional wheels were available in 1987 cast out of magnesium from Dymag in England and were available in 16-inch diameter and later in the year, a 17-inch size. In 1988, power levels increased. Horsepower was now rated at 382 and torque rose to 565 lb-ft. That year also saw the 17-inch Dymag wheels become standard equipment with other options such as an automatic transmission and full leather interior also was offered. Available for the 1989 B2K was the handsome Aerobody designed by Paul Deutschman and first seen on the Callaway Sledgehammer Corvette. It became available mid year on the production versions and replaced or installed over the lower panels of the car. 1990 brought more power once again. Horsepower rose to 390 and torque output was 562 lb-ft. however; the automatic transmission was no longer available. 1991 was the final year for the B2K option with power up again, this time to 403hp and 575 lb-ft. A subtle change to the hood included the installation of blisters to duct cold air to the intercoolers. The Aerobody, introduced in 1989 continued to be an option and late in the year, the Speedster model was revealed.

Exterior and Body Details

Corvette AeroBody was conceived by founder Reeves Callaway and designed by Paul Deutschman of Deutschman Design. Reeves explained: “We wanted to exploit the opportunity to re-engineer airflow management outside the vehicle for added stability in the 200 to 250 miles per hour window. Next, we wanted to revise internal airflow to provide additional engine cooling. Finally, we hoped to illustrate that aerodynamic panels could be designed to complement the beautifully integrated styling of the late model Corvette.” Callaway's efforts were proven when a prototype AeroBody kit was installed during Callaway “Sledgehammer” preparation. In October 1988, this turbocharged, street-driven C4 Corvette shattered the closed-circuit speed record with a run of 254.76 mph.
