Singer has unveiled the most extreme version of its highly modified and restored 911s to date at the 2018 Goodwood Festival of Speed. The Californian firm, which has gained notoriety backdating, updating and thoroughly customising aircooled Porsche 911s, has been working with UK-based firm, Williams Advanced Engineering to develop new upgrades for the new car’s engine, chassis and body. The project is known as the Dynamics and Lightweighting Study (DLS) and will form the basis of many future Singer restorations.
At first Singer teased us with renderings of its highly modified Porsche engine that showed a new induction system with an intake through openings in the side rear windows and a compact, yet complex, titanium exhaust system. What wasn’t visible from the images was the engine’s capacity increase to four litres, its four-valve per cylinder heads and its 9000rpm rev limit. The later we were given a taste of in a video of the engine in a test car. Hans Mezger, who designed engines for Porsche from the late fifties until the nineties, was also consulted during the development phase of the modifications.
Singer claims that its thorough engine overhaul increases the power output to 500bhp, an impressive 125bhp per litre. Performance is further improved with the significant weight loss program for the entire; the use of magnesium, titanium and carbonfibre has been used to reduce its kerb weight to 990kg.
