Hayashi Racing was founded by Masakazu Hayashi (Higashi Osaka City Japan). Masakazu was the driver of the Carman Apache, which gave way to what we now know as “Hayashi Wheels”. The lust for faster and lighter cars was on the forefront. During the time, the only construct for wheels was steel. Masakazu changed that with the introduction of aluminum made wheels. The first application and production of a Hayashi based vehicle was the Carman Apache. After Masakazu’s success with aluminum wheels, they become a must within the racing field. With time, the transition from race cars to road cars was in act (Hayashi Streets).
The Carman Apache made its debut in the 1969 Japan Grand Pix in Fuji Speedway on October 10th. It was entered in as a Class II, and was powered by Honda’s 1300 series engine. It was a SOHC air-cooled engine that incorporated Soichiro Honda’s DDAC (Duo Dyna Air Cooling system). Said system was created in 1968. It was comprised of a dual wall structure, where the outer wall of the cylinder block was connected to the structure in a two casting mold. The passage for cooling air was within the space of coolant flow ( in correlation to water-cooled engines). One fan forced cool air through the passages, while the other removed hot air from the engine. Factory figures for the 1300 based engine was 100ps, but with Honda and the RSC (Racing Service Club / Honda’s competition department) tuning the engine, it produced 135 hp at 7,000 rpm.
