By 1907, the manufacture of sewing machines had become unprofitable for Demorest, and the company was sold and restructured as the Lycoming Foundry and Machine Company, shifting its focus toward automobile engine manufacture. In 1910, the company supplied its first automobile engine to Velie, and during the early post-World-War-I era, the company was a major supplier to Auburn (which produced the Auburn, Cord, and Duesenberg lines). By 1920, Lycoming was producing 60,000 engines a year, with a 2,000-strong workforce. To handle the capacity, a new foundry complex was built in Williamsport that year. Eventually Lycoming became Auburn's principal supplier, and in 1927 Errett Lobban Cord bought the company, placing it under his Auburn Manufacturing umbrella group. Among the engines Lycoming produced for Cord was an L-head straight-eight engine of 298.5 cu. in. displacement that produced 125 horsepower. This was used in the Cord L-29. Lycoming also produced a double overhead cam straight 8 used in the legendary Duesenberg J series. This powerplant produced 265 horsepower, six times the power of a contemporary Model A Ford. A supercharged version, generating 325 horsepower, was installed in the Duesenberg SJ and SSJ models.
