    • The next level of M157 turbo upgrades - Weistec W.4 63 AMG M157 turbochargers with 1000+ horsepower capability

      The big guns are here. This is the next level of M157 performance. Introducing the Weistec W.4 turbocharger package which is a significant step up from the standard Weistec M157 turbo package. You could potentially think of this as a Stage IV package for 63 AMG M157 based vehicles.


      What 'Stage' to call this is not important. What is important is that these are big ball bearing turbochargers capable of flowing 65 pounds a minute which is good for over 1000 horsepower in theory.

      No doubt many of you want to put that theory to the test and BenzBoost of course wants to see it as well. We can not delve too far into the expected power numbers but what we can say is significant durability testing has taken and is taking place.

      What we can also say is that dynos will be coming and that this package applies to stock motor setups and built M157 setups as well. This includes rear wheel drive and 4Matic all wheel drive platforms. Obviously there will be a power and torque difference between stock and built M157 engines as far as what the motors can safely and reliably produce.

      Also, the Weistec upgrade is developed in a comprehensive manner. Meaning you can expect OEM detail to the entire driveline. Beyond this we really can not say much only that in due time you will see it all for yourself.


      So what is the big deal here? Well, obviously the big ball bearing turbochargers. Read it from Weistec themselves:

      "The M157 W.4 Turbochargers are ball bearing turbochargers featuring CNC machined billet aluminum compressor wheels capable of flowing 65lb/min. Each turbocharger features a specifically designed compressor cover that clears all the engine accessories (AC compressor, Alternator, etc.) and makes use of the stock charge piping as well as the stock wastegate actuators. Also integral to the design is the 3 inch anti-surge inlet providing the maximum possible flow to the compressor and helping prevent compressor surge."


      Make sure you focus on the line that states the turbochargers clear the engine accessories. Look, a lot of people will tell you they can fit big turbos on the M157. Few people can actually make it all fit in an OEM manner. That is where the 'Engineering' portion of the Weistec Engineering name comes into play. This is work by real engineers and not some back alley tuner hack job.

      The stock manifold design is a bottleneck on the M157. Weistec changed the entire design as you can see to be as efficient as possible. This is important to pay attention to:

      "The Weistec Turbo-Folds have 50% larger port area with increased manifold cross sectional area supporting much more flow, allowing the engine to safely generate far more horsepower and torque than any other available option. Despite being a totally new and larger parts, the Weistec Turbo-Folds are designed around the use of the Weistec True Downpipes. Those that already have the Weistec True Downpipes can be assured that no extra or new exhaust components will be needed."








      If you already have the Weistec 'True Downpipes' you are good to go and do not need to buy more components.

      The logical follow up question of course is how much money for all of this? Well, that information will come in due time along with further details. For now, M157 owners should be overjoyed that the platform is taking the next step forward which you might as well call it a leap forward as that is exactly what this is.

      KEY FEATURES:

      • Twin Ball Bearing Turbochargers
      • 65 Lbs/min compressor flow
      • Weistec M157 Compressor Covers
      • Weistec Cast Stainless Steel M157 Turbo-Folds
      • Custom Turbo Coolant Lines and Fittings
      • Custom Turbo Oil Lines and Fittings
      • Weistec Airboxes and Intake Piping
      • Bolt on installation
      • All hardware and gaskets are included
      • 1000+HP Capable with supporting upgrades
      • Designed to use Weistec True Downpipes
      • Reuses Stock Wastegate Actuators

        Right? This is how you professionally present your product.

        Not a one word or one picture instagram post.

        Absolutely and it also separates the men from the boys.

        Very nice. This will be an interesting comparison to the Full GAD-Motors Set-Up.Hope to see some Dynos or trap speeds soon.

        Awesome. I might have to keep the ML63 for myself when the Model X arrives now that these turbo upgrades are really taking shape.

        Certainly would be interesting to see a 10 second ML63.

        The Model X is awesome but it will be nothing like an ML63 with turbo upgrades.

        Modes GAD use new manifold with new compressor and turbine housing? Or do they modify the stock housing to accept the biggest wheel. Not familiar with there upgrade

        Absolutely. With Weistec's involvement in importing the 6X6 G63s, hopefully a customer (or Weistec themselves) mods a 6x6 with these turbos and all supporting mods and gets some performance figures.

        Heh you are going all the way to thinking of someone doing this on the 6x6 lol.

        I love that.

        Imagine 1000 horses... at all six wheels!

        Extremely well done. I actually planned to do something similar working with some AMG people in the UAE, but the deal fell apart, these things look awesome.

        Just happened to go to their site just now to check out the M157 section again after finding a particularly nice-looking car with an M157 in it...and saw these and came straight here to see what people were saying.

        This is amazing, really excited to see how far you can push these engines. I feel like I need this in my life, perhaps...

        It's attached, no worries.

        Still I don't think the GAD upgrade is on this level and would prefer to keep the thread on the topic of Weistec.

        I do understand GAD being brought up as they seem to be the only other option on the market currently for larger turbos.
