Singer Vehicle Design, the company behind plenty of resto-modded Porsche 911s, has announced it will be working together with Williams Advanced Engineering to develop a pretty special engine for their distinguished clientele.
As the company says in its official release: “the first fruit of this work is a modified, naturally aspirated, air-cooled, flat-six Porsche 911 engine with a 4.0 litre capacity, four-valves per cylinder and four cam-shafts, rated at 500 hp.” They didn’t mention it will be so aesthetically pleasing though.
That’s right, what started out as a 3.6 litre powerplant that provided 247 hp, has been enhanced to double its output. The new engine benefits from the expertise of the man who was responsible for the original in the first place, Hans Mezger, who is the technical consultant to the project.
The modernised 911 engine will go into a 1990 Porsche 911 that is currently being restored for one of Singer’s long-term clients, Scott Blattner, and full details about the reimagined 911 will be revealed later in September.
Aside from the brief details of the engine mentioned above, the new unit’s specifications include dual-oil circuits, new cylinders and pistons with titanium con-rods, aluminium throttle bodies with carbon-fibre trumpets, new upper and lower injectors, a carbon-fibre air box, Inconel and titanium exhaust system and an enlarged engine cooling fan.
There’s also a ram air induction system with pressure recovery in the intake plenums plus an extensive use of lightweight materials like titanium, magnesium and carbon-fibre. Where the stock 3.6 litre engine revs to 6,700 rpm, the Singer-Williams-modified one goes all the way up to 9,000 rpm.
“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,” explained Rob Dickinson, founder of Singer Vehicle Design.
If you would like a sample of what Singer is capable of (no, they are not related to that sewing machine company), take a trip down memory lane with this feature from Top Gear:

Dude… that’s not nearly double… that’s over double… Now their cars not only have the looks but the power to match…. wow…
Looks like a piece of art sculpture!
Errrrr…. Is this the same with Singer Sewing machine?
Oh yes. Senang dapat menjahit kalau ada Porsche.
NA , 4.0 liter , quad cam , 4 valves , 500hp , titanium magnesium ..no big deal..what the engine impressed me most was it AIR Cooled ! Rarely see the car that prefer air cool except the Epic VW beetle (old one ) and most all 90 and older 911. Some with turbo charged . Impressed Impressed.
Most piston powered airplane engines are air cooled…and they make way more power. likewise bikes and the odd ball Morgan.
Well, technically, your car engine is also air cooled in a way, just that the medium to transfer heat out is using water. In the Porsche design, they use oil (via an oil cooler), along with fins and heat exchanges on the block/head.
But yes, it is impressive no less.
Air cooling is actually a more reliable way to cool your engine as one of the most common engine failure is the failure of the (water) cooling system.
The move to water cooling is actually partly based on emissions. Firstly, a hotter engine needs more fuel to cool itself down (in fact, most of the cooling from the cylinder head is actually from the fuel itself), secondly, a more evenly heated/cooled cylinder head and engine has less hotspots, leading to pre-detonation, again needing a richer mix.
