• M156 versus M156, Black Series versus Black Series, Weistec versus Weistec - Supercharged Stage III+ 1000+ horsepower CLK63 AMG BS and 750+ horsepower Stage III C63 AMG BS go at it

      Some very interesting sibling rivalry to see here especially for M156 V8 63 AMG enthusiasts. Both cars here are Black Series with the W209 CLK63 AMG Black Series obviously being the older of the two using the 7G transmission with a torque converter and the W204 C63 AMG Black Series being the newer car featuring the newer 7-speed MCT Speedshift automatic which does not have a torque converter. Both cars have the M156 6.2 liter V8 although the C63 AMG Black Series has stronger engine internals and makes more power from the factory.


      The internals are strong for the C63 Black Series which still runs the factory engine internals but the CLK63 Black Series has a Weistec built motor setup with forged internal engine components. Those components are said to be good for over 1000 horsepower making them stronger than what the C63 AMG has from the factory.

      Regardless, both cars also employ the 3.0 liter twin screw blower used in Weistec Stage III supercharged applications. The difference being one is making much more boost as the C63 AMG is said to be somewhere around 11 psi. What boost and other mods the CLK runs is anyone's guess as the owner tends to be difficult to deal with thinking his car is the fastest thing on planet Earth whose setup should be treated with the same secrecy as nuclear launch codes as if on the same level of importance. The CLK is likely somewhere in the 9XX rear wheel horsepower range while the C63 is somewhere in the upper 6XX wheel horsepower range.

      So, on one hand we have similar base motors, although one built with aftermarket components, both running the same supercharger. On the other hand we have one car which has a Weistec built "Bulletproof" AMG 722.9 7G transmission while the other has the factory AMG 7-speed MCT. Weight is close from the factory but the CLK has been lightened quite a bit so that works in its favor. The CLK is tuned for race gas though while the C63 is tuned for pump gas.

      So what is the result? Well, not hard to guess but nice to see the comparison between the two cars. Video below.

        Cool then we're good. If I was being spiteful nothing would be up in the first place. I chose this to put up first because I found it the most interesting.

        That's exactly how I'm reading it, too. Kicking a guy when he's down....after YOU put him down just ain't cool in my book.

        Not kicking anyone when they are down never been my style or personality and he put himself down. You're cool with that behavior? I'm not and well end of that. Time to move on.

        The secrecy is fine, not my car but I can't talk about specs if I don't know them I can just talk about the specs I know. So when comparing the two setups I just wrote what I knew. Like it's hard to tell me, "oh hey that's not right" and then what? I won't change it?

        Well I can see how much my build was appreciated by this person you are defending. Like I ever disparaged this by making a joke in the manner that was done to me. Why don't I try some of that behavior and let's see how the forum responds? But oh, oh, because this guy happens to have a setup similar to yours that makes it somehow ok?

        The article is up, all coverage and posts proceed as normal, and if someone wants to participate here they should probably maintain a standard of decency. Too bad money doesn't buy you rep points... or class.
        Sorry I didn't realize your pump gas record figure would be a front page article. Didn't think so far. No sarcasm.
        I didn't really defend Jim as I said he creates interest and is also a cock tease. The whole mob did jump in though so its obvious it was in bad taste, wonder what it would take to put your rep in the red.
        In regard to the article, I am on your side. You wrote what you know at the time of writing. The 5 speed comment was a booboo. The race was one of the most anticipated cross forum races and bringing in the comedy you decided to bring in should have been put aside in my opinion.
        So chillax no one else called you a pussy.

        Well I found this one more interesting and a BMW race was already posted early this morning which people wanted to see considering the N54 bias so the next race will likely be that one. But you may notice since a BMW race was posted an article was needed for the Benz section and so this slotted in perfectly to avoid redundancy which I'm sure you thought of.

        Let me stick to running the site, thanks.

        Just a typo as I linked to the Weistec 7G upgrades with the 5-speed comment. Regardless, it was fixed in maybe what, 2 minutes?

        I'm not taking offense I explained myself simple as that. I think people getting worked up over nothing should relax as well. And yes, I found this particular race the most interesting hence why I chose to put up when and where I did.

        I am happy to see this video. I now have no regrets going the full monty on my car. Some days I had my doubts thinking this is enough but now I cannot wait for my race fuel to arrive to unleash the beast.

        I am on the standard stage 3 pulley that is meant to run 11psi. But at my altitude of 5600ft its lost 4psi so am on the week side of things. The car went into the body shop today for the widebody fitment (getting a thread ready now) so once that gets done will take it up to 11psi for street and race pully for track which I think is 17-18psi. At the moment I make my previous NA peak at 3600rpm so you can imagine the difference in the way the car drives.

        @Sticky, maybe this member needs a vacation. I don't see any positive inputs from him whatsoever. All he does is bash and disturbs the forum. What do you think?

        Out of respect to the membership I won't bother replying to you. So go ahead and do what you do best if it makes you feel better. I don't care
