More Power, Please: Wimmer RS Tunes Porsche GT2 RS to 703HP

With 620-horsepower on tap from the twin-tubo'd boxer engine for a 0-100km/h (62mph) sprint time of just 3.5 seconds and top speed of 330 km/h (205 mph), we'd argue Porsche's 911 GT2 RS is lighting quick. However, German tuning house Wimmer RS has a mind of its own when it comes to performance even if we're talking about a sports car that will be produced in a limited run of just 500 units.

The tuner's upgrades are concentrated on the 911 GT2 RS' 3.6-liter six-cylinder boxer which benefits from a remapped engine controller, optimized turbochargers, a sport air-filter, new air-intake and a valve-controlled sport exhaust system along with sport catalysts.

These modifications bump output from 620 to 703-horsepower, while peak torque rises from 700Nm to an even more impressive 810Nm or 597.5 pound-feet. According to Wimmer RS, the powered-up 911 GT2 RS can now complete the sprint from 0 to 100km/h in 3.3 seconds and pass the 200 km/h mark after just 9.5 seconds (stock model: 9.8 seconds), while continuing up to a top speed of 356 km/h or 221.2 mph.

Wimmer RS Brings a Surplus of Ponies to the Ariel Atom 3

Combine a 2.0-liter four-cylinder turbocharged Honda engine at the rear pushing out up to 300-horsepower with a lightweight construction that tips the scales at just 469 kg (1,034 pounds), and you don't need to be an expert to know that even in completely stock form, the Ariel Atom 3 is a one helluva pocket rocket.

Nevertheless, the tuning industry is always eager to push the limits on any type of vehicle. This time the culprit is Germany tuning house Wimmer RS, which has introduced a new power kit for the Atom 3 300.

The mods made to the four-cylinder engine by Wimmer RS include ECU optimization software, a compressor overhaul, a fuel pump conversion and a new sport exhaust system together with Rennkat.

The result is a whopping -remember, it's a 2.0-liter engine- 340 hp and 282 Nm (208 lb-ft). According to the German tuning firm, the power-upgrade helps this 469kg punk rocker of a sports car accelerate from zero to 100 km/h (62 mph) in a blink of an eye -2.8 seconds - while the 200 km/h (124 mph) mark comes after a mere 7.1 seconds.

For pricing details and availability you'll have to contact Wimmer RS.

Mercedes-Benz C63 AMG Receives Power Boost by Wimmer RS

When it comes to German tuners, the name of the game is power. The more the merrier. In its latest take on the Mercedes-Benz C63 AMG, Wimmer RS has presented the Level 3 performance kit, which increases the 6.3-liter V8 engine's output to 580-horsepower and 690 Nm (509 lb-ft), up from 457 HP and 600 Nm.

To bestow over 120 HP on top of the already potent naturally aspirated V8, Wimmer RS made a series of upgrades including the addition of a reprogrammed ECU, air filter from K&N, air induction optimization, a new sports catalyst and optimized cat-back all-stainless steel exhaust system.

The tuner also fiddled around with the the electronic speed limiter allowing the C63 AMG to reach a limited top speed of 305 km/h or 190 mph.

As an option, Wimmer RS offers a KW-Club Sport Suspension and high performance Dunlop Sport Maxx GT tires.

The cost of the full performance level 3 kit is set at €9,900 (about US$13,800 at today's rates) including installation.

Wimmer RS Turns VW Golf R into 478HP Red Devil

Red Devil is the name German tuning firm 'Wimmer RS' chose for its latest take on the Volkswagen Golf R. 'Red' because of the color chosen for the car, and 'Devil' because this Golf R packs a sinister punch under the hood...

In stock form, the all-wheel drive Golf R rolls out of VW's factory with a 2.0-liter TFSI producing 270-hp and 350Nm / 258 lbs-ft of maximum torque. After Wimmer RS's engineers perform their magic, those numbers increase to a whopping 478-hp and 610Nm or 450 lbs-ft.

The extra power comes from a variety of mods including -but not limited to- changes to the turbocharger, ECU, air intake, injection nozzles and exhaust system.

According to the tuning house, the upgraded Golf R can reach an electronically limited top speed of 291 km/h or 181 mph.

Additional performance enhancements include a coil-over suspension set and more potent braking system.

The German tuner did not release info on pricing.

Wimmer RS and Dunlop team up to create a 190-mph Mercedes C63 AMG Racer

Wimmer RS has turned its attention to the Mercedes-Benz C63 AMG to create the Dunlop Performance show car. The performance is there, so don't worry about the looks for now; this is just a rolling ad. What's under the vinyl and stickers is what Wimmer can do for the C63.

The car's electronically-limited speed has been elevated to 308 km/h (190 mph) thanks to reprogramming the ECU; with the addition of a flurry of intake and exhaust mods, the car puts down 540-horsepower (+53 hp over stock hi-po V8). Torque figures have not been released.

The speedometer hits the 100km/h (62mph) mark after 4.4 seconds (traction control issues, perhaps?) and then the next 100km/h goes by in another 8.2 seconds (0-200km/h or 124mph: 12.6 sec). Keeping the car planted on the ground is a KW3 coilover setup hidden behind 19-inch rims and possibly unmodified brakes (Wimmer didn't mention anything in the press release).

Now, for the real shocker: the 19s are wrapped in...drum roll please...Dunlop Sportmaxx GT tires (sized 235/35-19 in front and 265/35-19 in back).

According to Wimmer, the car seen here took place at the 2010 Tuner's Grand Prix at the Hockenheimring in Germany where it won runner-up. Nifty.
