1969 Season (Part IV)
the championship was already in the hands of Porsche, the races at Watkins
Glen and Zeltweg were also very animated. In Watkins
Glen two 908 Spyders were entered, as well as two privateer
entered 908´s, and three out of those four cars finished in the top
three places. In addition, Vic Elford with 908 obtained the Pole
While this happened, in Nürburgring different elements were tried and experimented on the 917 but, although they were vastly improved, then did not get to equal the times obtained by the 908 Spyder .

Zeltweg the 917 finally paid off. It faced his adversaries
and in spite of their congenital brake problem, things had improved enough. The
stability was not optimal, but now it was possible to be driven. All the
improvements were obtained during the official tests, and the position of the
front stabilizers was obtained by modifying the front end of the car. Thus it
was like the 917, until that moment an untamed horse, was transformed
into something more manageable.
addition, the Porsche engineers led themselves to obtain a good ventilation of
the cockpit, and reduced the fuel consumption on the basis of a new design of
exhaust pipes, which proved very complicated but very effective. With hard work
and thanks to thousand experimentations and loss of heart, the 917 was
present in Zeltweg, and in the hands of Siffert-Ahrens as
the winning car. And in third place, another 917: the one of Redman-Atwood.

PREPARATIONS FOR THE 1970 SEASON
Porsche “capos” hoped that the 917, with it’s modified tail,
known as "Hockenheim" was to be the quickest one during the
1970 Season. They had already thought about the organization who would sustain
their participation in the next year and for that reason, towards half-full of
September of 1969, Ferry Porsche and Ferdinand Piech met John
Wyer and John Willment in Zuffenhausen, which were the
main partners of JW Automotive Engineering to constitute a 7-car team.
Since recently the owners of the JWAE had signed an agreement with Grady
Davis (Executive Vice President of Gulf Oil), to introduce Gulf Oil in
motorsport, the new team would be called "Gulf Porsche".
first activity made altogether between Porsche and the John Wyer
Automotive organization, took shape in several test sessions in Zeltweg.
Conventional models and the experimental 917PA (a previous development
for Can-Am) were on that test.

The first joint activity between Porsche and John Wyer Automotive took place in various test sessions at Zeltweg. Conventional models, and the experimental 917PA (an unsuccessful development for the Can Am Series) attended such test.

docility of the ride.
modification, consisted in putting –in a rude manner- an aluminum device in
the rear end of the car, which resulted in an impressive improvement in the car’s
performance, which was ultimately reflected in the lap times, which were three
seconds faster. This would be the first step towards the future construction of
the 917 Langheck (long tail).

tires that had been used. With this change, lap times were improved another two

Preparation in John Wyer´s workshop
In January, 1970, three 917K (short tail) were delivered at the John Wyer Automotive workshop for preparation purposes, which included:
Installation of flexible tubing in the lubrication system to minimize the chance of a hot oil leakage in the event of an accident
Extra protection in light areas of the frame, which was designed to help protect against sand and rubber marbles
Addition of an anti-fire system
Tail section modification to host the increased tire measurement (from 12” to 15”)
