Singer Teams Up With Williams To Create 500-horsepower Porsche Engines
Based on the air-cooled Mezger designby Ciprian Florea, on
Created in 2009, Singer Vehicle Design has made quite a name for itself by modifying classic Porsche 911s. Combining state-of-the-art restoration techniques with tasteful implementation of modern features, Singer rolled out some of the most exciting 911 restomods on the market. Not just about visuals, Singer also handles the drivetrain department by rebuilding Porsche’s 3.8- and 4.0-liter flat-six engines with Cosworth and California’s Ed Pink Racing Engines. Now, Singer announced that it’s teaming up with yet another iconic company to build a new version of the flat-six. The firm in question is Williams, which has been racing in Formula One since 1977, winning nine constructors’ championships and seven drivers’ titles.
Singer and Williams will be working on engines commissioned by three clients for their air-cooled Porsche 911s. The first result of this collaboration will motivate a 1990 Porsche 911 currently being restored for a long-term Singer client. According to the company, the Mezger-designed, 3.6-liter unit from 1990 will be redesigned into a 4.0-liter with four-valves per cylinder and four cam-shafts. The engine will remain naturally aspirated and will crank out a whopping 500 horsepower, or as much as the current 911 GT3 RS.

Lightweight materials, including titanium, magnesium and carbon-fiber will be used extensively to reduce component mass and vehicle weight.
The new 4.0-liter engine is more than just an old 3.6-liter with increased displacement. On top of the four-valve cylinder heads, Singer and Williams will also add dual-oil circuits, titanium con-rods for the cylinder and pistons, and aluminum throttle bodies with carbon-fiber trumpets. The engine will also get upper and lower injectors for improved performance, and a carbon fiber air-box with active multi-stage resonator chamber for mid-range torque optimization.
Further updates will include Inconel and titanium exhaust system optimized for thermal performance and a CFD optimized and enlarged engine cooling fan, as well as Ram air induction system with pressure recovery intake plenums. Finally, lightweight materials, including titanium, magnesium, and carbon-fiber will be used extensively to reduce component mass and vehicle weight.
All told, this engine will be unique and more advanced than Porsche's current 911 units.
All told, this engine will be unique and more advanced than Porsche’s current 911 units. And, we’re talking about a 1990 design. This speaks volumes not only of this collaboration’s capability to completely overhaul on an old engine but also of the greatness of the air-cooled Mezger engine.
"This has been a fantastic opportunity to showcase the core capabilities of Williams Advanced Engineering. Having had the opportunity to consult with Hans Mezger – the “father” of the iconic air-cooled flat-six – about the development of the engine, our team was pleased to be able to provide a solution to Singer’s clients’ requirements and of course, to be a part of this iconic vehicle’s continued evolution," said Paul McNamana, technical director of Williams Advanced Engineering.
