    Awaiting fitment at the factory in 1987 is this 959 engine complete with lifting attachment. It gives us the chance to see a unit that is normally pretty buried in the engine compartment and to appreciate some of its details.

    Having a spare engine with you is always a useful backup when racing as is just having access to one, although if Porsche had not been able to supply a unit to John Woolfe at Le Mans after a practice misdemeanour damaged the original motor he would not have started and so not had his fatal accident. If you were running a 956 in the World Sports Car Championship it looks as though the same option was available, in fact it was said that one of the advantages of running a 956 or 962 when the Rothmans cars were racing was the fact that a wide range of spares were always available from their support trucks – at a price, of course.

      Another view of the above unit.

    There have been quite a few Porsche-engined Coopers, or ‘Poopers’ as they are sometimes called. This is probably one of the most obscure though, being built in the late 1960’s in Switzerland for hill-climbing using a six-cylinder unit. It is seen in Italy (at Modena) having its replacement rear bodywork constructed, although the nose section in the background appears to be standard.

    This four-cam engine appears to be being run up on a dynamometer, although for some raason with no exhaust extraction, in fact no exhausts at all! The heat, noise and fumes must all have been immense.

    An interesting view of a works 935 taken in May 1977 (probably at the Mugello circuit) and showing how the twin turbos were located in relation to the engine and indeed how the whole ensemble only just fitted into the car. While this unit was based on the 930 there were many differences (such as the traditional horizontal racing fan) that allowed it to produce just under 600bhp from 2856cc.

    Stopping the car was entrusted to 917-type brakes and the 935 quickly became one of the most successful Porsche competition models and also enjoyed a long career.

    There is no doubt as to the tuner responsible for this massive 930 intercooler.

    Although starting out with a 1.7L four cylinder unit, by the time that this picture was taken at the Nurburgring 1000Km in 1962 the 718WRS coupe (#046) had received the planned upgrade to the 2.0L eight cylinder unit seen here. The car, in the hands of the Porsche GP team pairing of Gurney/Bonnier, failed to finish on this occasion, retiring on the penultimate lap with a gearbox problem after practicing 3rd. That day Ferrari took the honours.

    In this picture of the engine bay of a 924 Carrera GT the intercooler for the turbo can be seen. This assisted in producing 210bhp, just a few horses more than a 911SC of the same period.

    Le Mans 1967 and a view of the engine of one of the two 910’s (#016 and #017) entered by the factory, showing those rather quaint little sets of inlet pipe protectors that they used. The former (Stommelen/Neerpasch) finished 6th from a grid 29th while the latter (Schütz/Buzzetta) qualified one place better but retired due to an oil pressure problem.

    Three 911 engines to compare, beginning with that of the original 930. In this shot taken on one of the first road tests of the car the extra pipework can clearly be seen, as can its effect on access to some of the other components.

    Next, one of the power units from the cars used in the US IROC (International Race Of Champions) series, where some of the biggest names in US and international motorsport battled it out in what was ostensibly the new Carrera RS in a variety of colours, although the identical cars were modified from standard specification in a number of respects. Single model racing really took off in the 1970’s and this series was one of the ultimate instances of this.

    Finally, a rare shot of the business end of a Brumos-supplied 934 and a very different engine from the units seen above. Racing in Group 4 and a development of the 911 Turbo rather than a purpose-built racing machine, it still produced 480bhp when introduced and this was later raised to 550bhp. It was very successful in competition, even finishing 4th overall at Le Mans in 1979. Perhaps these days its position in Porsche history is rather overshadowed by the 935 and it is easy to overlook just how many good results this model achieved.
