Porsche’s initial work with turbocharging their racing cars during the late 1960’s led to development of a turbocharged street version of the 911. While initially required to comply with homologation regulations, development continued when the rules changed. The new car was re-positioned as a fully equipped model to lead the 911 series and compete directly with the costlier and more exotic vehicles from Ferrari and Lamborghini.

Ernst Fuhrmann led development, adapting the technology developed for the 917/30 Can-Am car to the 3.- liter flat six from the Carrera RS 3.0. Suspension refinements, larger brakes and a strengthened four speed gear box rounded out the package. A functional “whale-tail” rear spoiler increased cooling airflow and provided rear downforce. Wider rear wheels and upgraded tires resided within flared wheel wells, increasing grip and stability at speed.

Simply known as the “Turbo”, the new vehicle was released in the spring of 1975, with export to the U.S commencing in 1976. In 1978, power output reached 300 h.p. with a displacement increase to 3.3 liters and the addition of an air to air intercooler. Porsche’s continuous development included slight revisions to the rear spoiler to accommodate the intercooler. Braking was significantly upgraded, with units similar to those of the 917 race car. Porsche’s careful development also ensured that the 930 was a sound base for racing vehicles and led to the successful 934 and 935 racing cars.
