With the introduction of turbocharged engines towards the end of the 1970s, Cosworth's naturally aspirated DFV began to lose its predominance. In an attempt to recover some of the performance deficit Cosworth designer [[Mario Illien]] reconfigured the cylinder aspect ratio to allow the engine to rev more freely, and combined this with a narrow-angle valve set-up and [[Nikasil]] Aluminium liners. The changes upped power output to ~520&nbsp;bhp,<ref name="motorsport02" /> and between 11000-12000&nbsp;RPM but this was not sufficient to keep pace with the turbo cars at most tracks, and it was only through a modicum of luck that [[Michele Alboreto]] was able to take what would prove to be the DFV-family's final F1 victory, at the [[1983 Detroit Grand Prix]]. The DFY lived on with back-marker teams until the end of the {{F1|1985}} season, when Cosworth switched their efforts to supporting the new turbocharged Ford GBA V6.
