• Kleemann's 770+ horsepower Mercedes-Benz C197 SLS AMG M159 V8 supercharger system released - Dyno, video

      The SLS AMG is already a very powerful car in stock form with its excellent naturally aspirated 6.2 liter M159 AMG built V8. Taking such a great motor and adding a little boost can only make it better right? How about to the tune of 770 horsepower from the stock 562-583 (depending on model year). Kleemann did provide a dyno substantiating their horsepower claims showing a peak of 770.4 horsepower a few hundred rpm before redline.

      As Kleemann is based in Denmark BenzBoost.com is not familiar with the dyno used or how this dyno would translate to numbers at the wheels on Dynojet to put the figures in context. There is obviously no doubt the Eaton TVS based system will add power and the pictured exhaust upgrades are stated as required by Kleemann to realize the full power.

      No USA pricing announced yet or if the specifications transfer over to 91 octane pump gas. Hopefully more details will come but until then enjoy the pictures, dynograph, and video below.

        You have enough fast cars and did some track time. You should be able to handle it.

        I just heard that the SpeedConcepts Kleemann SLS is not running properly, limp mode all the time . The owner of the vehicle contacted Weistec to see if they could re-tune it.

        Great job Kleemann LMAO!!

        I told Weistec to go ahead and fix it, I was really looking forward to running that car heads up on the track. Guy that owns the car posts over on PL and seems like a good guy, I feel bad for him having hauled the car all the way out to Vegas from Milwaukee and now it won't run propery. No sure what Weistec is going to do, probably not in their best interest to even touch the car, one of those damned if you do damned if you don't situations.

        Check the wheel sensor after he has trailing the car.

        I will pass on the info but which wheel sensor are you refering to? Also, what would traliler the car have to do with it? I have trailermy AMGs literally tens of thousands of miles and never had a wheel sensor issue or any issues related to trailer.

        Kleemann just told me this is completely untrue.

        SpeedConcepts does in fact have an SLS with our SC system installed. After being trailered to SEMA, the SLS drove 50 yards out of the trailer and went into limp mode. "ETC failure" was shown on the dash. Up until that point the SLS was 100% operable and performing as it should.

        According the the owner of the car, he asked many people, including Weistec, if they could help determine what might be his issue. Why shouldn't he- hes looking for help in place where there should be some level of community as far as he's concerned. I would not expect that another company would be thrilled to get involved with an issue that isn't theirs- but I do fully understand how an enthusiast with a problem, right now, will ask for help from any one that could conceivably give it. As it turns out it was a Snap On dealer that gave that help. What he didnt ask was for anyone to "re-tune" the car as a remedy, let alone a first step, in diagnosing the issue.

        The specific details were not given to me other than codes were found for the traction control system. Those codes are unknown to me at this time- and may never be known to me as they were erased. Once erased, the SLS was able to be driven, albeit to a display booth were it now sits until Friday night.

        End of the story? Hardly. Is it plausible that there is an issue with the car caused by a KLEEMANN provided item? Yes- its as plausible as any other of 1,000 other explanations for a failure that manifests itself by invoking "limp mode".

        One cannot be all things to all people. I am fully aware that people have their favorites, for all the good and bad reasons imaginable. We will always have supporters and detractors, as any other tuner will. For decades we have taken great pride in developing products that are reliable and do what they are intended to do. We stand behind what we produce and will continue to do so, this case is no different.

        We have no problem whatsoever sharing the outcome of this, it serves no purpose to hide or dodge the facts. It is far better to be honest about these kinds of events than suffer the supposition of the rumor mill or to be caught hiding the truth.

        Thanks for clearing this up and there should be some level of common courtesy in the community even though it is understood there is competition and business. We are enthusiasts ultimately I would think.

        Thats good and all @Sticky.

        But the question still remains:

        1- Why did the car throw an ETC code and continoued to stay in limp mode (Same issuse with the Grey SLS from Xtra Power). Exact same. So saying that they dont know what the ETC code is simply unbelievable!

        2- Why did the owner choose to ask Weistec for help instead of taking it to the shop that upgraded his motor or simply ask Kleeman?

        You cant compare the Kleemann with the old X-tra power.
        There is all new sw to the Kleemann, also the cooling element inside the Supercharger is new, it is on the M156 engine, so also in the M159 if i remember right.

        Given post 111, who at Kleemann told you it is completely untrue?

        I would take these guys to task for that.

        1. No diagnostic tools were available to the owner at the time of contact for him to relay any info regarding codes. How is it so unbelievable that we dont know the cause of an ETC failure on a car that has zero in common software wise with a car from Xtra-Power? The XP system used a piggy back ECU to modify signals back to an OE ECU, while this car has a reflashed OE ECU and had been running for months previously with no issues. Using your implied logic in 1, every time an SLS has a ETC failure and gets stuck in limp mode the root cause must always be the same and that root cause is known by anyone?

        2. The owner did contact us, and we discussed the issue with him at length. Without any kind of diagnostic info (MB Star Diag etc) the permutations of possible fault scenarios is nearly infinite. My assumption is the owner went looking for anyone who could help him read out the codes- EG: had a Star Diag tool, and another MB tuner is about the most logical place to start. Additionally, the owner is the installer, which is by no means a knock against him.

        I wrote Sticky an email explaining the situation as it was told to me by the owner of the SLS. Just as I will not be told by someone how to vocalize my thoughts, I am in no position to tell Sticky what to write. I can tell you that at no point in my email to him did I write those words, in fact what I wrote to Sticky is pretty much verbatim as post 111.

        This is all true.

        I should have more specifically stated the case but it was not my position to do so. I should have phrased it as there were inaccuracies. Regardless, thank you for providing supplemental information to clear things up.

        As already stated there are millions of different things it could or could not have been. Not sure why you can't understand that other than your constant cheerleading for other tuners.

        Maybe you don't read so well but the car was at SEMA - you suggesting they tow it back to the shop where it was installed 2000 miles away ?? Yeah that makes a lot of sense. Guy had an issue and as an enthusiast he started asking other enthusiasts if they could lend a hand and pull the codes. I seem to remember your friend @Sirex63 having lots of problems when someone else installed his blower and then went crying back to Weistec for their help. Same situation here so again, I'm not quite sure why you are asking such ridiculous questions.
