IT'S MOTORHEAD SUNDAY

Racing season in Wisconsin is pretty much over for the year so, on Motorhead Sundays, I'll be reaching back into the archives for some pix to share.

I've been reworking some TransAm photos from this past July and I thought you might like a quick review of some open wheel action in the Formula Atlantic class which is affiliated with the TransAm series this year.

FA was developed in the 1970s and was part of IMSA championships until 2009.  Currently, it is part of the SCCA (Sports Car Club of America) amateur racing series.

Typically the FA cars run 1600cc engines and have to compete in certain weight classes including driver's weight.  "Formula Atlantic as a class evolved in the United Kingdom in 1971 from the US Formula B rules, with 1600cc production-based twin-cam engines (initially Cosworth Mk.XIII based on Lotus-Ford Twin Cam and then Cosworth BDD, however other engines like Alfa Romeo were also eligible). Conceived by John Webb of Brands Hatch (who would later also develop the Sports 2000 class) as a category for national competitors with the performance near a Formula Two car but running costs at or below that of a contemporary Formula Three car. A single Yellow Pages championship ran in 1971-2, with a rival BPbacked series appearing in 1973. 1974 saw the BP series changing sponsor to John Player, and the Yellow Pages series becoming backed by John Webb's MCD organisation and Southern Organs; in practice most top drivers competed in both series and there were no date clashes. Only one series ran in 1975-6, in the final year taking the title Indylantic and adopting Indianapolis-style single-car qualifying. But the formula was under threat from Formula Three and no series ran in 1977-78. A BRSCC-organized club racing series returned in 1979 with initial backing from Hitachi and continued to 1983, with diminishing grids and few new cars appearing."   (WIKI)
