Porsche 917 construction report part 3 internals

After fitting the engine to the tube frame, I first manufactured the underbody – if you can say underbody to that part. In that years, the aerodynamical progress wasn’t very far. Primaly seven years later, Team Lotus discovered and introduced the ground effect in Fomula 1. Till then, airflow under the car wasn’t very important, the teams even try to prevent air stream under the car. Nowadays you want to get as much air under the car as possible for your venturi tunnel.

After fitting the bottom plate to the car, I began to assemble the inertials. Gearbox, parts of the rear suspension, pedal assembly, seats and so on.

The glass-fibre bodywork parts were glued to the tube frame.

The pedal arrangement.

Here you can see, the mounted pedals and brake fluid reservoirs. A little bit unusual, the clutch was operated by a bowden cable, not like in F1 with hydraulics. The big reservoir beside the brake fluid ones is the cleaning agent for the windscreen.

The 917 had an aircooled engine. Only an oilradiator was needed at the front end.

In nightraces, such as 24 hours, there were two batteries in the car for the current supply. The second one was beside the fuel tank.

The electrical main board.

The cockpit, filled with fire extinguisher, seats, electrics and pedal assembly.

The engine control.

The first parts of the rear suspension, the Bilstein dampers.

That's the car after four months of building.

My name is Paul Bischof. I’m a student in mechanical engineering at the Technical University of Graz in Austria, expected finishing in February 2016. Since I was eight years old, I am building model planes out of paperboard. Since 2004 I scratch (that means building without an assembling set) Formula 1 and sportscars in 1:10th scale. The average time I need for such a car is around 400 to 700 hours within 4 to 8 months. One car has around 3500 up to 5000 single components. On this blog, you can take a look on my work and later, after my studies, hopefully you can see me in Formula 1.
