Formula South Africa 1979-1986
With the cost of Formula Atlantic rising steeply, the South Africa AA announced new rules to come into force in 1979, banning the Ford BDA (Cosworth BDD) and mandating the use of engines that were classed as manufactured locally. Options included a 3-litre V6 push rod Ford engine, a 2-litre 4-cylinder single-ohc BMW, a 2-litre twin cam Fiat, a 2-litre 4-cylinder single ohc Ford and a rotary Mazda. The Mazda was available via the Sigma Motor Corporation, a motor vehicle assembler and distributor based in Pretoria, who used the 1146cc Mazda 12A engine in the Mazda RX-7. For racing equivalance, its capacity was regarded as double, so it is shown here as 2292cc. This engine quickly came to dominate Formula SA, and became the sole option when Sigma stepped in to sponsor the series from the start of 1981. Minimum weight had been increased from the 450 kg of the Formula Atlantic era to 480 kg for engines up to 2000cc, and 510 kg for bigger engines. This encouraged Ken Howes to buy a heavier Formula 2 March 792 for Ian Scheckter to drive, and ex-F2 chassis became the norm from 1980 onwards.
The new category was officially called the the SA National Championship Formula, but Leicester 'Sy' Symons, the influential Motoring Editor of the Rand Daily Mail, decided this was too confusing and coined the term Formula SA.
