As bright as the sun.

The most expensive new Porsche 911 money can buy these days would have to be the Turbo S Cabriolet kicking off at a hefty $200,400 in United States. The aftermarket specialist at Wimmer RS were not completely satisfied with the 580 horsepower (427 kilowatts) delivered by the biturbo 3.8-liter six-cylinder engine mounted at the back and decided to invest almost $55,000 to bump its output to a massive 840 hp (626 kW).

To extract an additional 260 hp (194 kW), Wimmer installed a pair of its own turbochargers and a custom intercooler. Not only that, but the tuners also fitted the 911 with a Saeco tube kit and a custom high-pressure pump, while a BMC high-flow filter and a new stainless steel exhaust system were added as well.

With all the upgrades in place, the six-cylinder engine now generates a mountain-moving 634 pound-feet (860 Newton-meters) of torque. In case you were wondering, that’s an extra 118 lb-ft (160 Nm) over the regular model.

Thanks to the added oomph, Wimmer says its heavily modified Nine Eleven will run from 0 to 62 mph (100 kph) in only 2.6 seconds, thus making it 0.4s faster than a stock 911 Turbo S Cabriolet fitted with the Sport Chrono package. The 0-124 mph (0-200 kph) sprint will take a mere 8.4 seconds, or a full two seconds less than the regular version. Hit the track or an unrestricted portion of the Autobahn and the tuner says it will do 0-186 mph (0-300 kph) in 17.9 seconds. There’s no word about top speed, but most likely it has increased a little bit over the standard 205 mph (330 kph).

In order to cope with the extra power of the engine, Wimmer had to modify the PDK transmission and it now has almost $6,700 worth of upgrades. Rounding off the list of changes is KW’s Clubsport suspension priced at $6,100.

In 1963, the sensational Porsche 911 was presented to the public. The seventh generation of the Nine eleven is now called 991. Its top models Turbo and Turbo S have rear axle steering and are fascinating eye candy in the convertible version as well. Exactly that stunning constellation – a Porsche 991 Turbo S Convertible - received a lavish performance increase at WIMMER Rennsporttechnik in Solingen.

The entire engine electronics was scrutinized and sections underwent a detailed revision. The installation of two WIMMER turbo chargers and sport camshafts as well as intercooler have been implemented. Also the cylinder head machining, the pistons and connecting rods received a professional upgrade. The fuel pump, the intake manifold and the throttle valve also experienced some adjustments.
Furthermore, a high-pressure pump, a BMC high flow air filter for the suction optimization and a Saeco tube kit was provided. The icing on the cake, however, is the WIMMER-RS stainless steel exhaust
system with an electronic throttle system equipped with two 100-cells sport catalytic converters by HJS.
The costs for the engine modification amount to 52.500 Euro.
The result is beyond astonishing! The original power of 560 PS has been catapulted to a mighty 840 PS. The results are a brutal 860 Nm maximum of torque and a breathtaking Vmax of 364 km/h. That offers the ideal conditions in order to launch from 0 to 100 km/h in 2,6 seconds, from 0 to 200 km/h in 8,4 seconds and from standing position to 300 km/h in 17,9 seconds!

In addition, a KW club sport chassis for 5.850 Euro as well as PDK modification for 6.400 Euro are obtainable.

The vehicle - including the complete conversion - is available at WIMMER for 310.000 Euro.
By the way, the orange colored vinyl wrap attracts attention!
