Singer evolves restoration of air-cooled Porsche 911s

By CARSIFU | 1 July 2023


LOS ANGELES: Singer, a California-based luxury specialist that restores air-cooled Porsche 911s, has evolved the Dynamics & Lightweighting Study (DLS) to incorporate turbocharging (DLS Turbo).

The Singer Group restores and reimagines 1989 to 1994 Porsche 911s, based on the 964 chassis at the direction of its clients.

Rob Dickinson, executive chairman and founder, Singer Group, said, "“The results of turbocharging our advanced 4-valve, high-revving DLS engine have been quite spectacular and combining it with all we have learned about lightweighting and vehicle dynamics has provided the perfect canvas to honor the Type 934/5 and its vital role in the genesis of the 911 as a racing car.”

Mazen Fawaz, CEO, Singer Group, said, "Our Dynamics & Lightweighting Study heralded a new era at Singer and facilitated enormous maturation of our operations in California and the United Kingdom. We’ve collaborated with some of the most famous names in the automotive world, including Bosch and Michelin as we continue our mission to set ourselves ever higher standards. We will continue to serve our creative and passionate client base with exciting new ideas like DLS Turbo.“

As with all Singer’s restoration and modification services, the engine from the owner’s Type 964 Porsche 911, is the starting point.

The engine is disassembled down to the engine block before being restored using high performance components and modifications to optimize performance.

The unique, 3.8L, 4-valves per cylinder flat-six 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 HP at more than 9000 rpm.

Meanwhile, the restoration process begins when the owner of a Type 964 Porsche 911 sends their car to Singer with the request to carry out a personalized restoration.

Originally manufactured by Porsche between 1989 and 1994, these sports cars have been enjoyed for thirty years.

The owner’s car is carefully disassembled. The interior is removed, as is the exterior bodywork and all mechanical components, until the steel monocoque (chassis) is revealed.

The chassis is painstakingly assessed, cleaned, strengthened, and prepared so that it is in optimal condition for the next stages of the restoration.

The car in Blood Orange has been specified by its owner to emphasize track performance, featuring a high-downforce rear wing with adjustable upper element and a track-oriented front fascia with larger splitter.
