California restoration home turns 1990 911 into rally-bred, twin-turbocharged Safari monster.

US-based Porsche restoration specialist Singer has unveiled the All-Terrain Competitors Research (ACS), a rally-ready model of the basic Porsche 911 impressed by the 959 Safari and different ‘safari’ fashion Porsche rally automobiles of the Eighties.

Developed in collaboration with British Porsche 911 rally specialist Richard Tuthill, two examples of the ACS had been commissioned by a long-term Singer consumer: one designed for “high-speed desert rallying” completed in Parallax White, and one other constructed for “high-speed, high-grip tarmac occasions” and painted in Corsica Pink.

The commissioning buyer has allowed Singer to facilitate different clients eager on securing a Singer ACS of their very own, and whereas a worth has but to be introduced, they will probably need to pay a major sum for the privilege.

Based mostly on a 1990, 964-generation Porsche 911, the Singer ACS has been fitted with a bespoke light-weight physique, with carbon-fibre panels “suited to fast substitute” and “straightforward underbody entry”, and a strengthened monocoque chassis designed for off-road use.

Off-road suspension with round 265mm of suspension journey hides beneath the swollen wheel arches, with twin five-way adjustable dampers fitted to every nook, delivering a significantly-increased trip peak over a normal 964-series 911.

A set of 16-inch cast aluminium wheels wrapped in BF Goodrich all-terrain tyres fill the arches, and conceal four-piston metal brakes linked to a hydraulic handbrake contained in the cabin.

Powering the whole bundle is a 3.6-litre, twin-turbocharged model of the long-lasting ‘Mezger’ air-cooled flat-six engine, growing 336kW of energy and 569Nm of torque – although the mill’s precise outputs may be tuned to satisfy “the calls for of every occasion”.

Water-to-air intercoolers and a radiator mounted contained in the entrance clamshell feed the six-cylinder engine, which sends drive to all 4 wheels by means of a five-speed sequential gearbox and a everlasting all-wheel-drive system.

Entrance, centre and rear mechanical limited-slip differentials are standard-fit, as are an assortment of different off-road goodies together with a long-range gas tank and two full-size spare wheels, one at every finish of the automobile.

Inside, occupants sit in FIA-certified, competition-spec bucket seats, and are surrounded by a FIA-specification roll cage completed in pink and black. The driving force and navigator each profit from a hydration system, with the latter given entry to a race GPS navigation system managed by way of a big touchscreen.

On the skin, the Singer ACS attracts quite a few styling cues from the Eighties Porsche rally automobiles that it is impressed by, with a single-piece entrance clamshell, 959 Safari-inspired rear finish, gold Singer badging and twin central exhaust ideas.
