    • Weistec Engineering releases M113K (kompressor) 3.0 liter supercharger upgrade for supercharged 55 AMG models

      Rejoice W211 E55 and 55 AMG fans, the day is finally here. We first announced that this upgrade was being developed in December of last year and as usual Weistec diligently worked on it and delivered as promised. The 3.0 liter supercharger upgrade is officially on the market. There are several advantages to the 3.0 liter twin screw versus the factory 2.1 liter namely in the areas of efficiency and heat management which is vital for a positive displacement application.

      The factory 2.1 liter supercharger weighs 50 pounds more than this upgrade. This is partially due to the solid steel drum of the clutch rotating assembly. In addition to the weight the way the supercharger is designed/placed has the intercooler in the valley of the V8 meaning it will get hot rather quickly due to heat from the engine rising out directly into it. Heat soak is a large issue with the M113K cars and there is a long history of W211 E55 owners in particular complaining about heat management. This issue will be mitigated considerably with the Weistec supercharger which has the intercooler fully floating within the lower manifold casting. Basically, airflow will cover the Weistec intercooler from all sides resolving the issues with heat soak.

      This all boils down to a larger, more efficient, and lighter supercharger. More power, less weight, and the ability for repeat runs without losing that same power. Yes, exactly what M113K owners have been asking for. This same supercharger currently powers the fastest Mercedes in the world on the M156 motor platform and is a proven commodity.

      The W211 E55 AMG sees a restriction at the point of the throttle body. Now remember, since this is a positive displacement design the car pulls air through the throttle body into the supercharger. The E55 was limited in this area by Mercedes likely to appease SL55, S55, and CL55 owners who had a larger throttle body. The factory 74mm can be upgraded by Weistec to 82mm with the supercharger upgrade eliminating a vital restriction point through which air passes to the compressor.

      The supercharger kit retails for $8,649 and includes the following pieces:

      Key Features:


      • 3.0L Twin-Screw Compressor Module Why Twin-Screw?
      • 1000hp Liquid to Air Intercooler Core
      • High Flow, Cast Aluminum, T6 Hardened Lower Manifold
      • High Flow, Cast Aluminum, T6 Hardened Intake Elbow and Throttle Body Inlet
      • Maintains Factory Electronic Bypass Valve
      • Hard Anodized Front Drive Bracket with Double Bearing, Belt Wrap Idler
      • HD 8 Rib Belt Tensioner
      • HD Supercharger Serpentine Drive Belt
      • High Flow Billet Fuel Rail System
      • 650cc Fuel Injectors
      • Molded Silicone Air Pump and Throttle Body Coupler
      • Weistec Weaved Cotton Fiber Air Filter
      • New OEM Gaskets
      • Saves 50 Lbs. vs Factory Kompressor
      • Weistec Engineering, M113K S1 SC Reflash



      Power figures with dyno graphs will be released shortly and detailed in a separate article. Congratulations to Weistec for delivering yet another great Mercedes product. Pictures are below, hurry up and order yours as there is no doubt this will be a very popular upgrade on the platform.

        Guys, the Kleemann supercharger for the n/a engines. It is not a replacement for the 55k stock blower.

        No not this past week, they said either this week or next. So, I would expect them at some point next week.

        Those have a different motor.

        I am pretty sure the C55 Kompressor has a de-tuned version of the E55 motor and guys with regular CLK55s have been bolting up 55 blowers for quite some time, so why would this not work or be made to work?

        Damn,this is awesome. Makes me miss my E55 even more now. It just sucks that repair costs&parts for a W211 E55 are still astronomical. Even though the cars can be bought in the $20-30k range you still have to pay for parts on a $100k car. The parts dont get any cheaper from MB&the W211 wasnt the most reliable in the electronics department.

        What's the difference between this kit and the 3.0lt for the 63 motors?

        They run the old W210 E55 M113.

        There is no C55 Kompressor model.

        You can supercharge those motors but they are different from the M113K motors. Similar basic architecture but different internals and other design difference like the ECU.

        You might be able to adapt this with a custom build but it would require building those motors, getting a tune for the different ECU, etc. Not as simple as bolting this on like you can with the E55 which is already supercharged.

        The motor application and tunining. It's the same basic blower but with differences to run on the M113K instead of M156.

        Is the 63 motor justified the 6k price hike then?

        I would think so as making the supercharger work on that application is likely much more difficult than upgrading a car already supercharged with a positive displacement blower.

        The tuning has to be more difficult and more involved on the M156. So the cost difference is not as much hardware as it is software and development.

        5k extra for software?
        I would like to see a detailed list of both kits and what comes with them.
        Ps: the 2.3lt kit for the 63 is 15k even, and this is the 3lt @ 8k. No doubt the 63 kit should be a little more expensive but that much more expensive? Im just curious to see the differences in the kits.

        Not the software itself but what went into tuning the setup. Like I said, getting the M156 supercharged and tuned is MUCH more difficult than the older M113k. Remember, the M156 starts naturally aspirated and this is a big difference. It also is a higher compression motor with a more sophisticated ECU.

        So, all the development time that went into it is a factor.

        Isn't that posted?

        Yep. You aren't paying just for the hardware. Look at the VF-Engeering R8 V8 supercharger which is $25k yet the RS4 system that uses the exact same blower is $13k. That one is a little tougher to explain.

        Somethings I just don't understand!! Either way my plan is to have a weistec 3lt on my car this time next year. I'm just curious to see how 2 kits which I assume are very similar yet priced so differently.
