Porsche M96 3.6 specs: 219.4 ci 6-cylinder, 96 x 82.8 mm (3.7795 x 3.2598 in) bore and stroke. Rod ratio and piston speed worked out.
The Porsche M96 3.6 is oversquare — the 3.7795" bore exceeds the 3.2598" stroke by 15.9% — a layout that favors airflow and RPM over leverage at the crank. The 3.2598" stroke does not reach 4,000 ft/min of mean piston speed until about 7,350 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 36.6 ci (599 cc).
It is one of 11 engines in the M96 family, the largest at 219.4 ci.
