Singer and Williams create ultimate 911 engine

Singer has undertaken a project to restore a 1990 911 for a long-time customer, and the first step was to work with Williams to create the ultimate air-cooled engine.

To give additional insight into the engineering marvel that is the Porsche air-cooled engine, they’ve also recruited the man who helped keep them running, Porsche engineer Hans Mezger.

The Mezger-designed 3.6-litre flat-six was modified to a 4.0-litre capacity, given four valves per cylinder, four cam-shafts, and aluminium throttle bodies.

Cylinders and pistons link with titanium con-rods, the air box is made of carbon-fibre, and the exhaust system is one of titanium. The concoction of materials also includes magnesium for some components to reduce the vehicle’s overall weight.

On top of those and other impressive modifications, it revs to over 9000rpm, and is rated for 373kW. It’s got a fair bit more kick than its original 184kW.

The engine will power a 964 911, which will have its full specs, modifications and design revealed in September after its completion.

Signer founder Rob Dickinson says the project is being undertaken for one of Singer’s clients, Scott Blattner.

“Helping our clients realize their unique vision for a reimagined Porsche 911 with the help of automotive royalty is very much a privilege,” Dickson says.

“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.”

Despite greatly altering certain mechanical components of classic Porsches, Singer says its work should never detract from the original machine built by the German marque.

“This incredible machine should never under any circumstances be referred to or described as a “Singer,” “Singer 911,” “Singer Porsche 911” or a “Porsche Singer 911,” or in any other manner that suggests that it is anything but a Porsche 911.”

That goes to show just how fanatical Singer is with the Porsche brand.
