California-based Porsche specialist Singer, has evolved their recent Dynamics & Lightweighting Study (DLS) to incorporate turbocharging. These latest modifications result in the DLS Turbo, a Porsche 911 reimagined by Singer. The DLS Turbo is their take on the victorious 934/5 endurance racers of the 1970s.

The 911 began as a naturally aspirated car, undergoing careful development over the years to optimise road and track performance. Beginning in the mid-1970s, the turbocharged 911 emerged and underwent a similar evolution. In 1977 this led to a racing variant of the 911, known as the Type 934/5, which dominated the SCCA Trans American series, winning 6 of the 8 races and the championship.

The process begins when the owner of a Type 964 Porsche 911 sends their car to Singer with the request to carry out a personalised restoration. The owner’s car is carefully disassembled. The interior is removed, as is the exterior bodywork and all mechanical components, until the steel monocoque is revealed. The chassis is painstakingly assessed, cleaned, strengthened, and prepared so that it is in optimal condition for the next stages of the development.

Some owners prefer their DLS Turbo’s be track-focused, while others prefer a road-focused set-up. The car in featured in Blood Orange is an example that has been specified by its owner to emphasise track performance, featuring a high-downforce rear wing with adjustable upper element and a track-oriented front fascia with larger splitter.

The second car in Moet Blanc has been specified to be road-focused, including an aero-optimised rear ducktail spoiler and road-oriented front fascia which reduce drag. Owners may request that their Type 964 is modified to accept both aero configurations. The front fascia and rear decklid assembly can be removed and switched, allowing ultimate personalisation and freedom of choice for each owner.

The DLS Turbo is powered by a unique, 3.8 litre, 4-valves per cylinder flat-six which uses twin turbochargers, with electric wastegates, air-to-water intercooling and a horizontally mounted, electrically powered fan. This evolution of the engine developed for DLS restorations enables power outputs over 700 bhp. A 6-speed manual transmission sends power to the rear wheels. Track-oriented suspension and bespoke dampers with remote adjustment are among the details that may be considered.
