Singer, the renowned specialist in luxury restoration of Porsche 911, has introduced turbocharging to their Dynamics & Lightweighting Study (DLS), giving birth to the straightforwardly named DLS Turbo. Text: Luca W. © Images: Singer Group Inc. ©

Honouring turbo racers’ legacy

In partnership with owners, the study aims to pay tribute to the 934/5 models from the 1970s. The 934/5 enjoyed a remarkable career in the SCCA Trans American series, clinching victories in 6 out of 8 races and securing the championship title. Drawing inspiration from this era, Singer enhances the aesthetic appeal of the DLS Turbo by incorporating design elements reminiscent of that time.

Rob Dickinson, Executive Chairman and Founder, Singer Group, Inc.:
“I was 12 when my father’s friend showed us his Super 8 film of the 1977 Watkins Glen 6 Hours. As the familiar face of a Porsche 911 morphed into impossibly boxed hips, gaping intakes, and a giant double-planed rear wing, I can still remember the shock and the realization that this was the other life of the 911 – the racing car. Since Singer began, I’ve wanted to return to that moment, collaborate with our clients and celebrate that car – the 934/5.”

The expertise and restoration process

The restoration process, limited in numbers, follows a straightforward approach: starting with the owner’s Type 964 Porsche 911, all parts are meticulously removed until the chassis is fully exposed. The chassis then undergoes a thorough cleaning, strengthening, and preparation for the subsequent restoration stages.

Handling components

Based on the customers’ preferences, Singer installs a track-oriented suspension with bespoke dampers that can be adjusted remotely. To maximize performance, carbon ceramic discs and monobloc calipers are paired with Michelin Pilot Sport Cup 2 (or Cup 2R) tires, mounted on forged magnesium wheels measuring 19″ inches in the front and 20″ inches in the rear.

Bodywork and aerodynamics

As expected, owners enjoy a wide range of exterior and interior personalization options to suit their preferences. However, all bodywork components share a common trait: carbon fibre construction to enhance stiffness and reduce weight.

In the DLS Turbo study, aerodynamics takes centre stage, with numerous parts optimized using Computational Fluid Dynamics (CFD). This includes the front intake, hood vent, rear fender intakes, NACA ducts for brake and turbocharger cooling, and a substantial rear wing inspired by the iconic 934/5 model.

One car for one driving profile

The DLS Turbo study offers two distinct trims: one focused on track performance and another tailored for road use, each with its unique characteristics.

The track-focused trim boasts an adjustable high downforce rear wing and a larger front splitter, resulting in a more aggressive overall appearance compared to its road-focused counterpart.

The road-focused trim prioritizes drag reduction, replacing the large rear wing with an elegant, aerodynamically optimized ducktail spoiler and a more conventional front splitter.

Owners still have the freedom to choose their preferred elements from either trim, allowing for a fully customized experience.

Let’s talk about the big guy: the engine

At the heart of every Singer restoration lies the engine, which is meticulously disassembled down to the block before being equipped with cutting-edge components.

The result of a collaboration between Williams Advanced Engineering and Singer, the co-developed 3.8-litre flat-six engine now features twin turbochargers, delivering over 700 HP at an impressive 9,000 RPM. The turbochargers benefit from electric wastegates, air-to-water intercooling, and a horizontally mounted, electrically powered fan.

To ensure a near-perfect driving experience, all power is transferred to the rear wheels through a 6-speed manual gearbox.

Porsche Singer price: DLS Turbo

As previously mentioned, every restoration is a unique reflection of the owner’s desires, making it challenging to assign a specific price. However, the comprehensive restoration process is estimated to start at a minimum of $2 million, regardless of the exclusivity of the limited number of restorations.

For those who keen to see the car stretching around before buying it, the public debut of the DLS Turbo will take place at the 2023 Goodwood Festival of Speed in July (UK) and the 2023 Monterey Car Week in August.
