Volkswagen DH specs: 1.9L (117 ci) 4-cylinder, 94 x 69 mm (3.7008 x 2.7165 in) bore and stroke. Rated 82 hp, 1983–1985.
The Volkswagen 117ci (DH) is oversquare — the 3.7008" bore exceeds the 2.7165" stroke by 36.2% — a layout that favors airflow and RPM over leverage at the crank. The 2.7165" stroke does not reach 4,000 ft/min of mean piston speed until about 8,850 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 29.3 ci (479 cc).
3 factory variants share these dimensions, rated at 82 hp across 1983–1985.
