Singer Vehicle Design has announced that it is working with Williams Advanced Engineering and Hans Mezger to create the ultimate aircooled 911 engine.
Californian company Singer Vehicle Design has announced its latest 911-based project: a new engine option for its 964-based Porsche 911
Reimagined by Singer. The project has seen collaboration with Williams Advanced Engineering – with porsche engine legend Hans Mezger consulting.
The aim of Singer’s latest project is to create the ultimate aircooled 911 engine. Headline figures released by Singer are 493bhp at 9000rpm, from a 4.0-litre naturally aspirated flat-six. Singer also wanted to reduce overall weight, a feat that Williams has achieved.
Based around the 1990-spec 3.6-litre engine block, capacity has been enlarged to 4.0-litres as with the regular Singers. The big difference comes in the form of four-valve cylinder heads, titanium conrods new aluminium throttle bodies with carbon fibre trumpets. Lightweight materials have been used throughout.

The entire induction system has been re-engineered with a new carbon-fibre airbox, making use of an active multi-stage resonator chamber for improved mid-range torque. The ram-air induction system makes use of the rear side window-mounted intakes. The exhaust side hasn’t been ignored either, with a full Inconel and magnesium system – optimised for thermal efficiency.
Rob Dickinson, Founder of Singer Vehicle Design, explains: ‘Helping our clients realise their unique vision for a reimagined Porsche 911 with the help of automotive royalty is very much a privilege. Singer is delighted to be working with Williams Advanced Engineering and Hans Mezger to offer our clients a “next level” of restoration and modification services for their Porsche 911s. With careful and dedicated development, this iconic air-cooled engine has much to give both its existing devotees and a generation of new enthusiasts.’
More details of the project are expected to be revealed alongside the latest commission for Singer client Scott Blattner, the car in which the first of the Williams-engineered powertrain is to be fitted.
