The success of Callaway Turbo Systems led to a formal arrangement with Alfa Romeo to turbocharge their 2.5 liter sports coupe, the GTV-6.

The Callaway Twin Turbo GTV-6 was a low-production, high-performance flagship, giving the Alfa platform a new round of exposure. It also allowed Callaway to demonstrate its proficiency at meeting the testing, documentation and production standards required by Original Equipment manufacturers. The Callaway Twin Turbo GTV-6 performance caught the attention of Dave McLellan, Corvette Chief Engineer. The project was instrumental in triggering the Callaway-Corvette association.
