    • 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.

        Absolutely awesome! Plus it saves 50 lbs, damn, that's good.

        I wonder why you chose that placement for the intake filter? Seems like things could get hot under the hood right there. But, I'm sure there's a reason.

        I'm not surprised - this package appears to be priced quite reasonably.
        I wonder if those who have pre-ordered / ordered it also have a myriad of other modifications, and if so, how efficiently it'll mate with those mods?

        It will work very well with the other mods namely headers, exhaust, heads, etc. Anything that improves breathing will mate just fine.

        Pricing is very reasonable.

        Very impressive - congrats @Weistec I'm sure these things are going to fly off the shelves at that price and it makes me want to pick up a low mileage E55 and mod the $#@! out of it.

        Same thing I was thinking. Wish they put this motor in an ML55.

        IIRC they did make an ML55 I remember driving one that a friend of mine had. Or, was that the non supercharged 55 ?

        Check this thing out - sweet interior too:

        It had the previous V8 from the W210 E55 without the supercharger.

        Yep, that's perfect. E55's are an incredible bargain now.

        Got it, thx. Yeah, there are a few very low mileage E55's out there. Want to see how much power Weistec is getting out of these things...Have you heard any estimates ?

        No estimates yet but I would think 6XX on pump is not unreasonable?

        This is all they really needed. Everybody pushed that poor stock blower as far they could.

        I wonder why the SLR was excluded from the application list?

        I agree with you 100%. So many supercharger bearing problems i've read about. Even that didnt scare me though. The ONLY thing that keeps me at bay from buying one is the suspension failures they seem to have. Very expensive problem, sometimes each corner of the car is 1000 each to repair. If they all fail at once, thats 4k to repair....pretty nightmarish.

        Can't you just ditch the stock suspension system for some coilovers?

        Was gonna say the same thing. Can't be that difficult to convert to coil overs, upgrade sway bars etc...

        I've read that its possible, but not a whole lot of people do it. I guess they like the comfort suspension setting for drag racing lol. hmmmm.....*scrambles on autotrader to find e55's*
