Firsts and Lasts in Motorsports

[Stan Reid]

The first and last engines to win the Indianapolis 500 with a mechanically driven supercharger:

First: A Duesenberg straight-8 codriven by Lora Lawrence Curum and Joe Boyer in the 1924 event

Last: A Sparks straight-6 driven by George Robson in the 1946 race

I believe that 1924 was also the first year engines with a mechanically driven supercharger competed in the 500. The last year, not counting the turbines of 67 and 68, were some Offenhausers in 1966 with a Roots type supercharger.
