    • 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.

        Naturally aspirated motors have been supercharged since the beginning of time its not like black magic, pricing is reflective of the cost of the vehicle.

        Actually Full Throttle, according to many tuners and large scale companies, what we proved to be extremely successful with the M156/M159 was black magic. Development costs and understanding how to put positive pressure through a highly complex engine, and manage all this with the factory electronics was not an easy task.

        RNZ-11Z, we are dropping prices on our M156 systems so hang tight! The M113 Supercharger System has half as much components as the M156 system. As an example, we change the complete drive system on the M156 system, whereas the M113 system is kept fairly OEM with the exception of a stronger belt tensioner and billet retaining bracket. The M156 system also has a mechanical bypass valve that requires many moving parts, whereas the M113 has an electronic bypass valve that is carried over from the factory system. Hope this helps.

        The assumption of them being similar is solely based On hardware used and not application. BMW's use similar turbos as other cars but the hold up is tuning and the time and cost involved as always.

        Thanks for the info weistec. Much appreciated Click here to enlarge
        if I wasn't traveling, building my rx8, I would be charged by now. I'm hoping to go the built motor and 3lt charger sometime next year. Happy to hear a price reduction too Click here to enlarge

        I have no issue with the pricing just pointing the pricing trends for similar products across different platform lines.

        You aren't understand the different application for the similar hardware. You can't just say oh it costs so and so for this motor so it should cost so and so for another motor. Doesn't work that way. Just cracking the M156 ECU to begin with is a huge undertaking. Who else has done it really? Weistec was first.

        ESS has been "working" on theirs supposedly for years now. It really isn't as simple supercharging an AMG V8 as it is a domestic.

        Look at the cost difference even between similar motors like the M156 and M159. The SLS system is more expensive due to design differences despite a similar base.

        I didn't even realize Kleemann had anything and if they do it doesn't even compare to this blower and is likely way more expensive.
        Kleemann don't have a S/C for the M113K, they have it for the N/A SL550, But I do remember their Kleemann S7 project but i dont think they work on it anymore. They do have the Kleemann K5 and K6 mapckage but it wasn't really worth the price and power I would recieve

        My SL55 was a full Kleemann car with some things done here and there including a weight loss of almost 200lbs back from the dealer when it was ordered on a special request back in 2003. Close to the 680-670hp barrier. Car would fly the torque was a lot more than expected. A special thanks to 0-60Motorsports for helping me achieve what I wanted more of a brother than a friend, until two weeks ago I was informed by him that Weistec are launching this. We are ordering the kit for the SL and ordered a big heat exchanger kit too. We both plan to hit the 1000hp mark with this modifcation as what Weistec announced "Our 3L Supercharger can make up to 1000hp with the proper supporting modifications"


        Lets hope for the best and lets get this build started eh Ejaz?

        yeah tell me about it. Well I'll be working with WEISTEC to try and make this happen, If not now then in the future. But right now the goal is to get the kit on the car with a good tune, put on the dyno and fine tune it and go from there. @Weistec have been amazing throughout the process and now were just waiting on the kits to be ready for dispatch.

        I'm sure they will, well they did help @0-60Motorsports anyway.
        Looking forward for the build and what happens next! @Weistec will be getting many updates and videos through out the build. Maybe a couple of races too against a 722S Click here to enlarge

        We'll have to do our own dyno runs once the kit gets installed bro as @Weistec will have to adjust the tune based on your cars current mods.....

        Everyone is waiting, they are just so busy. The 3.0 liter upgrades and the M156 stuff has been taking up their time lately.

        I'll ask them again, it's coming don't worry.
