Yahoo Autos The Route to Singer's Ultimate Reimagined 911
Singer's restored and reimagined Porsche 964 powered by a naturally-aspirated flat-six enhanced by Williams Advanced Engineering is one the most highly anticipated cars debuting at the Goodwood Festival of Speed this weekend. 125 horsepower per liter from an air-cooled six-cylinder, which also happens to make an amazing noise? That's right:
Internally known at Williams as the P67, Singer calls this restoration the DLS, which stands for Dynamic Light-Weighting Study. It took three years to develop, with test driver Marino Franchitti benchmarking it against such souped up contemporary Porsches as a 991 GT3, a Sharkwerks-tuned 997 GT3 and a Cayman GT4. It pairs 500 horsepower with 2200 lbs. of stunning beauty.
And speaking of power, not only does the Williams-built 4.0 Mezger flat-six have four-valve cylinder heads, but it also features dual oil circuits, titanium connecting rods, aluminum throttle bodies, carbon fiber intake trumpets, and a carbon fiber air box. No wonder why it will rev above 9000rpm.
On Williams' side, this F1 tech heavy project was lead by Vehicle Dynamics Engineer Alan Clark, Chief Vehicle Integration Engineer Jonathan Dean, and Engine Program Lead John Magee. Both Porsche engine legend Hans Mezger and racing aerodynamics mastermind Norbert Singer were brought in as consultants. And the moment of truth is near. This weekend, at Goodwood, the Williams flat-six will sing.
