Porsche 911 S

Het voertuig in detail

For 1972, Porsche increased the 911’s engine size to 2.4 litres, by increasing the stroke from 66mm to 70.4 mm. Forged crankshafts were also used, the con rods were shortened by 2.2 mm and the big ends increased in width. The design of the lightened rods had been proven in the 917’s flat-12 racing engine.

A dry sump oil tank was relocated from a position behind the right rear wheel to a spot ahead of it. An external filler door was added so that oil could be added into the tank from outside the car. This move was made to improve the handling balance of the car.  Koni shock absorbers were also standard equipment for the top-of-the-range S model, along with new 15mm front and rear anti-roll bars, and a steel front spoiler. The new 905 5-speed gearbox had a greater torque capacity and was easier to use. First gear was in line with second gear for a change!
