“Now THAT’S a Doozy.”
The Duesenberg Model SJ featured a supercharged version of the Model J’s straight-eight engine. In addition to many race-bred features such as double overhead camshafts operating four valves per cylinder, SJ models were equipped with centrifugal superchargers that further increased the engine’s performance. The car was so powerful that promotional materials of the day stated that a Duesenberg owner could be passed by another car only when they wished to be passed. To match prestige with power, the body of every Duesenberg was coachbuilt, including this convertible coupe by Walter M. Murphy Co. of Pasadena.
