Paging through South African motorsport archives, their names crop up on many occasions. More often than not because, under the banner 'Alconi' (a shortened combination of Adler and Conchie) and as part of the Ecurie Aquila team, they managed to make everyday cars into circuit-racing giant killers – in 1966 an Alconi R8 won the South African Group 2 title for saloon cars.
So impressive were the results and reliability that Alconi and Renault South Africa teamed up to offer clients road-going Alconi R8s and R10s fully backed by Renault head office and sold through its dealer network.
It wasn’t only Renault though and race results showed that in ’63 Conchie teamed up with Adler in the freshly released Fiat 1500. Although the race season wasn’t exactly a top showing, the road tests on their Alconi-modified OTS road cars raised a few eyebrows. In standard guise, the 83hp 1500 scampered to 60mph in 14.5 sec, 80mph in 34.3 and had a top speed of 91.8mph. The 96hp Conchie/Adler OTS however dropped the sprint numbers to 11.7 and 24.4 seconds respectively and bumped the top speed up to just shy of 100mph thanks to a modified camshaft with more lift and duration, a reworked distributor, Weber 36DCD7 and better matching of the manifolds to the head.
