Racing Beat's founding duo, Jim Mederer and Takayuki Oku, began modifying and building rotary engines for racing applications back in 1972. It was a classic case of the American automotive engineer meeting the Japanese racer that brought these two unlikely partners together. Together, many early successes came while building engines for dirt track midget cars, IMSA R/S class RX-2's , Car and Driver Magazine's Bonneville RX-4, and Racing Beat's RX-3 NHRA drag car.
