Repco had been involved in Australian motor racing many years prior to the association with Brabham. Most famous had been development of the engine of the series of Maybach Specials in the 1950s to various wins including the 1954 [[New Zealand Grand Prix]].

The Brabham-Repco project was initially aimed at the [[Tasman Series]], where [[Coventry-Climax]]'s obsolete FPF four-cylinder engine was dominant in the mid-1960s. The 2.5-litre version of the Repco V8 was never very successful in this series, initially producing no more power than the FPF. It did, however, record one Tasman Series round win with [[Jack Brabham]] driving his Repco powered Brabham BT23A to victory in the 1967 South Pacific Trophy at the [[Longford Circuit]] in [[Tasmania]].

Brabham-Repco's were also prepared and entered in the 1968 and 1969 [[Indianapolis 500]]. In 1969, [[Peter Revson]] finished fifth in such a car. He also won a USAC race in the same year.

1969 saw [[Leo Geoghegan]] drive his [[Lotus 39]] powered by the 2.5L Repco V8 to victory in the inaugural [[Japanese Automobile Federation]] (JAF) [[JAF Grand Prix|Grand Prix]] held at the [[Fuji Speedway]] in [[Japan]].<ref>[https://www.youtube.com/watch?v=elrUxONKCNw&t=322s ALEC MILDREN RACING 1969 JAF Grand Prix]</ref> The race was run to [[Formula Libre]] regulations with 2.5L cars mixed with [[Formula 2]] and 1.6L cars.

Further versions of the V8 engine were produced, including a 4.3-litre variant for sports car racing and a turbo-charged version intended for [[United States Automobile Club]] races. Neither version met with any international success, the turbo in particular being labelled 'Puff the Tragic Wagon' by its development team due to its lack of horsepower (compared with "[[Puff, the Magic Dragon]]").

The sports car engine (increased in size to 5.0 litres) was, however, dominant domestically, powering cars to several wins in the [[Australian Sports Car Championship]] and its predecessor the [[Australian Tourist Trophy]], most notably powering the [[Matich]] sports cars built and raced by [[Frank Matich]], and [[Elfin Sports Cars]] built and raced by [[Garrie Cooper]].
