Porsche 911 S

Slight technical modifications on the valves and the exhaust lead to a new codification of the engine which becomes of type 901/06 as of November 1966, without otherwise the power does not increase being fixed at 130 hp.

On the other hand, as planned from the start, a new, more powerful engine is fitted in the 911, which is then called 911 S. This engine, still with a displacement of 1991 cm3, sees the power rise to 160 cv Din at 6600 rpm for a torque of 179 Nm at 5200 rpm. Its codification is of type 901/02.

To reach its new power, the connecting rods are nitrided, the pistons are forged and no longer cast with an increase in the compression ratio which goes from 9.0: 1 to 9.8: 1, the valves have a larger diameter and the exhausts are modified also. The Weber carburettors are of type 40 IDS and the initial weight of the engine of 184 kg does not change that it is in 130 or 160 cv. Small detail to notice if a coveted 911 is well equipped with its engine S, the deflector behind the turbine must be of red color.

Thus, the 2.0S will develop 160 hp, the 2.0 T, 110 hp to position itself as entry-level and the 2.0 L will develop 130 hp.

Until August 1968, the 911 will remain with the famous short chassis (SWB). Porsche will then try to bring a solution to the very characteristic handling of the Porsche 911. The technicians of the factory modify their flagship model and increases the wheelbase of the 911 of 5.8 cm to go from 2,210 m to 2,268 m. If 5.8 cm seem little on paper, they are enough to significantly improve the handling of the Porsche 911, without distorting its character that is all its charm …
