Mercedes is preparing to end production of the SLS and replace it with the smaller SLC, but tuners are still paying lots of attention to the famous supercar. Danish tuner, Kleeman, is one to show its interest in the SLS by coming up with a pretty cool tuning kit.

The kit offered by Kleemann focuses on maximum power, and the tuner transformed the SLS into the beast we’ve always wanted to see. A base SLS is powered by a 6.2-liter, naturally aspirated V-8 engine that delivers a total of 583 horsepower — not bad for a Mercedes, but not the best for a supercar.

Kleemann decided it can do better, and came up with an in-house-developed supercharger made from aluminum. This blower increases the base output to an amazing 770 horsepower and 623 pound-feet of torque. With the extra power in tow, the SLS now sprints from 0 to 60 mph in in just 3.3 seconds, from 0 to 124 mph in only 9.3 seconds and up to a top speed of 221 mph.

Along with the new supercharger, the tuner also installed a new polished-stainless-steel exhaust system that features a bolt-on cat-back system, a dual mid-muffler, an "X" pipe and a remote-control exhaust flapper. This new exhaust system further improves the sound delivered by the V-8 engine, and you can adjusted from a neighbor-friendly purr up to to the sound of a race car.

There is also a new catalyst section that delivers a enhanced sound and freer exhaust flow, which allow the new supercharger to operate more effeciently.

Danish Mercedes-Benz / AMG performance tuner KLEEMANN A/S has developed a tremendous power package for the already fast and tremendously well manufactured SLS AMG.

The SLS AMG‘s high revving 6,2 L normally aspirated V8 engine is changed into a furious power house by the KLEEMANN SUPERCHARGER, the signature product of the Danish high performance tuning specialist. The in house developed and manufactured Supercharger system is manufactured from billet aluminum, carefully milled out from solid alloy blocks, and black anodized. The fi nished assembly looks and feels factory, there is no disappointment when the bonnet is popped.

In the highest performance trim, the exhaust system has undergone a complete redesign as well. The optional polished stainless exhaust system comes in 2 variants. A bolt on cat back system with a dual mid muffl er and X section plus a fl apper controlled rear section. This can be operated with a remote control for neighbor friendly sound levels to the sound of a race car. the addition of new catalyst section gives the super car an even better sound, and most importantly, it frees the exhaust fl ow and the heat buildup against the engine allowing the Supercharger to be geared to a higher ratio. The combined exhaust and ratio change safely adds 50 more horse power.

Nine months of work and thousands of testing hours has not only made the system work fl awlessly, but given it the feeling of driving a factory car, just much more powerful. The engine builds power smoothly all the way to the rev limiter, the engine does not feel supercharged at all. Torque production is immediate and ever present through the rev range, no matter what gear or RPM, there is tire roasting torque available.

The KLEEMANN power package gives the super sports car explosive power under the long bonnet of the SLS. 770 HP and 845 NM rockets the KLEEMANN SLS against the horizon.The result is quite breathtaking. Even with ESP on, the Continental tires will scream for mercy. The ESP works as hard as it can, but to no avail, the warning lamp will fl ash up to 150 km/h before it is off duty. 0-100 km/h arrives in just 3,3 seconds. The digital numbers in the center of the cluster jump in incomprehensible chunks as it reaches 200 km/h in only 9,3 sec. The same unstoppable tempo persists, passing 300 Km/h as quickly as more pedestrian cars pass 100 km/h. The V-max is unlimited, the KLEEMANN SLS runs right into the rpm limiter in 7th gear where the digital cluster shows 356 km/h.Few ground-moving vehicles can match the performance of the KLEEMANN SLS.
