The famous RM Sotheby’s auction house is going to sell a 1:4 scale replica of Porsche 917’s engine during tomorrow’s “Driven by Disruption” exhibition.
The engine replica was crafted by one of Canada’s most respected engineers, Herb Jordan, over a four-year period, between 1980 and 1984. A very important fact to be mentioned is that the engine is fully operational.
Jordan has also been well known for building, in his house workshop, his own rotary-valve motorcycle and a Formula III racing car. After building another functional scale model of the Porsche Type 904 engine, he drew up the plans for the much-desired 917 mill.
He used a 10-inch lathe, a drilling machine and other small tools to create parts from aluminum alloy, brass and steel for this incredible replica. The flat-12 displaces 54 cubic centimeters and spins at a maximum of 24,000 rpm.
To get a better impression of how small this engine is, you should know that the crankshaft is made out of a single billet and the mechanical fuel injection pump is the size of half a pencil.
It also features a direct-port mechanical fuel injection, the tiny oil lines are wired-braided, and it also has hand-made crafted cylinders and cam covers. The engine has great performance on methanol with the help of two very small turbochargers, according to RM Sotheby’s.
This collector’s item measures 15 inches long by 8 inches wide by 7 inches tall and weighs about 15 pounds. The only thing that probably will give you spine tingles is the price. The famous auctioning house expects to get between $20,000 and $30,000 for this incredible fully functional 1:4 scale 917 engine.
RM Sotheby’s strongly advises the buyer to thoroughly service the engine before use because, although it has been fired up a lot of times when Jordan built it, the engine hasn't been started in years.
Porsche first introduced the mighty Le Mans winning 5.4-liter engine in the 1960’s and the twin-turbocharged 917 model dominated the Can-Am series with its ability to produce as much as 1,500 horsepower.
