Singer Vehicle Design, makers of the most impeccably restored and reimagined Porsche 911 models the world has ever seen, has teamed up with Williams Advanced Engineering (part of Williams Grand Prix Engineering Group) to build a 500hp (372kW) engine that will help propel a few lucky customers to illegal new speeds.
Now 372kW might not sound like that much of a big deal in our modern world… but when you consider that the motor in question is based on an original air-cooled Mezger flat-six dating back back 1990, well, it’s pretty damn mind-blowing.
Sporting a 4.0-litre capacity this incredible feat of engineering uses four-valve cylinder heads, dual oil circuits, special titanium connecting rods, aluminium throttle bodies, carbon fibre intake trumpets plus a lightweight carbon fibre air box.
Williams also designed a unique ram-air system, the intakes of which are neatly mounted within the frames of the car’s rear quarter windows. Smart. Very smart. Other trick bits include a CFD optimized and enlarged engine cooling fan plus an exhaust system fashioned from titanium and Inconel (once the reserve of F1). Singer claims that their new Williams-built engine will rev over 9000rpm – something I know that I’d pay money to hear. – Thomas Falkiner
