 In 1973, Reeves Callaway, not in a financial position to be able to start his dream of embarking on a racing career, did what many aspiring  drivers do—Callaway went to work as a driving instructor for Bob Bondurant's racing school.While using the newly launched BMW 320i as a school car, he became familiar with its intricacies and deficiencies, he later took hold of one of its cars to his garage in Old Lyme with the intention of tuning for more power.As a result, Callaway constructed and installed his first prototype turbocharger system and offered Car and Driver journalist Don Sherman the opportunity to drive the car resulting in a one-page article, giving the modified car great acclaim.
