1986 RUF Porsche 930 Flatnose BTR

Finished in Guards Red with a Black Leather interior this left hand drive 1986 Porsche 930 Turbo Flatnose was first registered in the UK in April 1989 and originally supplied through Porsche in the Netherlands it was well optioned from new, the most obvious of course being its distinctive body shape. This vehicle started life as a genuine factory Flatnose or 'Flachbau'.

As if a 911 Turbo Flatnose didn't stand out from the crowd enough, early in the car's life it was sent to world-renowned Porsche tuners RUF Automobile GmbH, who are recognised by the German government as a manufacturer in their own right. The customer opted for a BTR conversion (B = Group B, T = Turbo, R = RUF).

The basics of the RUF BTR start with the engine, which had the original partially-finned cylinder barrels replaced by those with air-cooling fins around their complete diameter. The bore was increased giving a new displacement of 3.4 litres from the original 3.3 litres. RUF added unique Mahle Pistons plus connecting rods and 935 type camshafts. The intake manifold was replaced, as was the exhaust, A larger KKK K27 unit replaced the turbo, and a larger free-flowing intercooler was added along with the installation of a larger oil cooler behind the RUF front spoiler. 

RUF also went to great lengths to modify the standard Porsche 930 4-speed transmission by adding a 5th gear with the help of Getrag. Next, the shift linkage was improved, becoming both lighter and more positive than the stock unit. The cars were lowered and the suspension was stiffened, RUF also fitted their single-piece forged alloy wheels, sized 9x17 and 10x17. 

Inside, RUF added an adjustable boost control, changed the steering wheel to an in-house RUF item and added custom gauges together with a half roll-cage.

The conversion produced some rousing statistics: power increased from 300bhp to 374bhp, top speed reached 187mph, and the 0 to 60mph sprint was completed in a staggering 4.4 secs. It was at this point a RUF BTR became the fastest accelerating production car ever. RUF had even bettered the performance figures for Porsche's own Group B Le Mans car!

Thought to be 1 of only three 930 Turbo Flachbaus ever to have been through the genuine RUF conversion process having an estimated new-build value of £250,000.

With only 42802 kms (26751 miles) showing on the odometer this distinctive RUF Porsche 930 Flachbau is presented in fantastic condition inside, outside and under the hood with its driver's handbooks and relevant paperwork in place.
