Sports Car Digest – “The 917/30 of 1973 was, for all intents and purposes, an all-new car when compared to its predecessor. At the heart of the car was an enlarged 5.4-liter flat 12-cylinder engine – turbocharged, of course. Along with the larger capacity engine, the 917/30 featured dramatic, low-drag bodywork. To address issues discovered during the 1972 season, Porsche enlisted Charles Deutsch’s SERA of Paris to advise on a suitable body shape and to hone the design in the Eiffel wind tunnel. To cope with the increased performance, Porsche extended the wheelbase, upped the fuel capacity, provided strengthened lower wishbones and designed special extractor turbines to aid in brake cooling.
The result of this extensive development was a sports racing car that weighed just 1,765 lbs. at the curb and produced over 1,000 hp – a monumental figure for a sports racing car. With the boost turned up, over 1,500 bhp was achievable” - The full story via the link above for this awesome machine.
Hemmings Daily report – Possibly the first space frame Porsche 550/1500 RS Spyder to cross the block. This August, a Porsche 550 Spyder, possibly the first constructed with a space frame instead of the original ladder frame, will cross the block as part of Mecum’s Monterey sale.
“Mecum states that the was imported into the United States in 1973, and it was acquired by its current owners, Peter and Cheryl Dunkel, in 1989. A full restoration was undertaken, including a rebuild of the Type 547 engine by noted authority Bill Doyle. Though most of the car remains period correct, the finish is reportedly a more contemporary Metallic Silver, with a red and yellow Porsche livery sprayed across the hood for better on-track visibility. As an homage to the car’s original owner, the cockpit tonneau cover caries the names of the races campaigned by Christian Goethals.
Research on 550-0077 revealed that a total of three engines were installed in the car, with the current engine, serial number 90089, fitted during Goethals’ ownership. That makes it among the most original examples remaining, and its history and condition earned it an award at the Porsche Rennsport Reunion as well as a Design Achievement Award at the 2011 Dana Point Concours d’Elegance”
