917 - 16 cylinder version, 6 litres. Fiberglass intake manifold, cooling fan, engine ducting.
In case the 12 cylinder 4.5 litre motor wasn't enough, Porsche put this together, basically a doubled 3 litre 8 cylinder, mechanical injection, power off the middle of the cranks shaft like the 12 cyl. This couldn't have passed muster with the FIA for 5 litre prototypes, they might have stroked it down, producing something breathtakingly over-square. At 6 litres, as shown, it apparently made 800 hp...
What you see here is almost all plastic - fiberglass car body, fiberglass intake trumpets, flanges for sets of 4, cooling fan, TWO 16 cylinder bakelite distributor caps, 16 plastic hoses from the Kugelfisher fuel injection pump to each intake trumpet. The top of the engine is, of course, a fiberglass air duct directing the horizontal fan's output to the cylinders and heads. Plenty of PVC insulated electrical wires and little rubbery booties on the distributor wires...
The only metal visible is the cases of the cockpit instruments, steering wheel spokes and hub, roll-bar, master electrical switch and tank caps, chassis tubes (black) and foil heat barrier, alternator (forward right on the engine), the hub of the fan and the Kugelfisher inhjection pump. And the torque tube linking the two sets of throttles.
