Singer presents ‘Dynamics and Lightweighting Study’ at Goodwood

The results of the California auto restoration house Singer Vehicle Design’s Dynamics and Lightweighting Study (DLS) will be displayed at the 2018 Goodwood Festival of Speed in West Sussex, England.

DLS is a collaboration with Williams Advanced Engineering, a subsidiary of the Williams Grand Prix Engineering Group that runs the legendary Williams Formula One Grand Prix team, and a conglomeration of technical partners, with the goal of creating the most advanced air-cooled Porsche 911 in the world.

The highly anticipated results will be featured in a static showcase outside Goodwood House and in action during the Michelin Supercar Paddock Hillclimb Run.

The project began back in 2017 when Singer client and Porsche enthusiast, Scott Blattner, requested that high-performance enhancements and weight reduction work be done on his 1990 Porsche 964.

To meet the goals defined in collaboration with Scott, Singer engaged Williams and other technical partners to engineer a selection of restoration and modification services oriented toward shedding weight and yielding dynamic gains.

Amongst other work, DLS delivered Scott a car with a plethora of modifications, including a normally aspirated, air-cooled Porsche flat-six, developed by Williams Advanced Engineering with technical advice and consultancy from Hans Mezger. The 4.0L powerplant, features four titanium valves per cylinder, extensive use of magnesium and lightweight materials to reduce mass, lightweight throttle bodies with Formula One-inspired upper and lower injectors to enhance performance and drivability, and a unique and optimized oiling system to improve lubrication and cooling.

Together, these mods help the engine to produce 500bhp at 9,000 rpm.

Williams Advanced Engineering along with technical advice and consultancy from Norbert Singer developed the car’s aerodynamics. Every surface on the vehicle was re-assessed through computational fluid dynamics (CFD) analysis.

Results of this include the elimination of front axle lift through the redesign of the front oil-cooler intake and venting.

Other modifications include a new front splitter, the optimization of the ducktail spoiler, the addition of a roof-channel and roof/rear window spoiler created to generate downforce at the rear of the vehicle. The optimization of the engine’s intake and cooling performance through side-window ram-air intakes and rear deck-lid venting help keep the car cool.

Williams Advanced Engineering & RLE did a full weight reduction study that also prioritized torsional stiffness, mass efficiency, and driver environment. It resulted in mass relocation by moving the engine forward for optimized chassis balance, and full, ultra-lightweight carbon fiber bodywork.

Bosch worked on the car’s control systems including the ABS, traction control and electronic stability control (ESC). Switchable driving modes were developed that included the option for the traction control and stability systems to be turned off.

Williams Advanced Engineering did extensive suspension work to the Porsche, designing a lightweight multi-link, double wishbone, front suspension, a lightweight, aluminum, rear trailing arm, with integral brake cooling and Formula One-style bespoke mass-optimized dampers with remote adjustment.

The car’s transmission and drivetrain were worked on by Hewland and included a Bespoke, 6-speed gearbox using magnesium casings with hollow shafts for maximum reduction of rotating mass, a length reduction to reposition engine forward for optimized weight distribution and the addition of motorsport-style tripod joints, center-lock wheel carriers, and modern materials.

World famous brake manufacturer Brembo, enhanced the Porsche’s stopping power by utilizing the latest technology CCM-R carbon ceramic high performance, lightweight discs and lightweight, monobloc calipers, developed specifically for the study.

Michelin provided bespoke-sized Pilot Sports Cup 2s tires developed by Michelin’s Development and Manufacturing team in Greenville, South Carolina. They feature a Bi-Compound asymmetric design and Variable Contact Patch 3.0 technology. The fronts are 245 / 35 / 18 with 295 / 30 / 18s in the rear. They were mounted to lightweight 18” forged magnesium, monobloc, center-lock wheels developed for the study by BBS Motorsport.

Lightweight carbon fiber sports seats were specially designed with Recaro, and Momo contributed a lightweight carbon-fiber steering wheel specially developed for DLS.

Unique interior bits include a raised manual gearshift with exposed titanium and magnesium linkage and shift lights integrated into the tachometer, drilled carbon and titanium pedals, a lightweight air-conditioning and heating system and instrument gauges with hand-applied characters, floating in a carbon fiber instrument panel.

“The Dynamics and Lightweighting Study has been years in the making,” says Singer Vehicle Design’s Founder and Creative Director, Rob Dickinson.

“To see the results, representing the ongoing pursuit of our client’s vision for their ultimate air-cooled 911, is so exciting. We’ve worked relentlessly to present a machine that visually celebrates the past while acknowledging the future – both inside and out. It’s our fourth year at this incredible event, and we’re thrilled to be back at Festival of Speed for its twenty-fifth anniversary and to wish Porsche a very happy 70th birthday.”

Mazen Fawaz, CEO of Singer, said, “The extraordinary collaboration of our partners – names like Williams Advanced Engineering, Bosch, Brembo, Hewland, Recaro, MOMO, RLE, EXE-TC and BBS Motorsport – have made this crazy vision become a reality. Not only did they believe in us, but their engineering might have delivered nothing short of spectacular results, above and beyond our expectations – and allowed us to achieve truly sensational, technologically advanced results for our clients.”
