    • Eurocharged and Pure Turbos combine to produce the most powerful stock internal GLA45 AMG and M133 - 442 awhp

      This GLA45 AMG belongs to Benzboost member @Meltingtires. Previously it was incorrectly reported that another company did the tuning on the vehicle. Well, Eurocharged Canada handled the tuning and they managed to get an impressive 442 all wheel horsepower out of it.


      The car has the Pure Turbos M133 turbocharger upgrade and supplemental methanol injection. The previously posted graph showed 435 whp 444 wheel torque but Eurocharged Canada ended up hitting 442 whp and 450 lb-ft of torque at the wheels on a Dynojet in SAE correction:

      Custom Eurocharged ECU Tune
      Pure Upgraded Turbo
      Weistec Catless Downpipe
      Snow Performance Meth Injection
      AMS Center Heat Exchanger
      AMS Aux Heat Exchanger

      442 WHP & 450 WTQ on Pump Gas


      Incredible numbers from the M133 2.0 liter motor.

        I read somewhere (and it's bothering me that I can't remember where) that Mercedes-AMG is stopping development on the M133 engine due to thermal management issues, mainly high cylinder head temperatures. For some reason I don't really believe that since the platform doesn't seem to be known for these problems.

        But my question is, have tuners run into any of these issues? I know these motors run very high boost from factory but what are boost levels on something like this? How is the thermal management on these motors coping?

        I think the only reason Mercedes stopped development is they are moving to a new modular engine family. I haven't heard of engine issues.

        M133 engine mod wise is not even in the same league as the golf R engine and Audi rs3 2.5 litre

        i mean as far as modding them Golfs and Audis are killing the game and these little AMGS just cant keep up

        The AMG gearbox is the crappiest of all car companies and is just not up to the task

        You may be right. The motor isn't having trouble making power though.

        The Golf's and Audi's have more tuners tackling them as well.

        I am a big AMG fan boy but m133 is not a good a good platform world record is only 11.6 or something like that

        There are lots of turbo kits on the market now and plenty of options of mods

        Its just not a good platform somebody needs to go out and prove me wrong

        With dyno graphs above these cars should be running flat 11s and 10s but no signs of that yet

        I know of a golf here in AUS mk6 with 400whp runs 10.5 stock engine with APR bolt ons

        It's a 2.0 liter motor not too many people are pushing. 11.6 out of it is impressive IMO.

        Give people a chance to hit the strip with these setups. I wouldn't discount it as a whole just because nobody has run a low 11.

        I don't see too many people drag racing these in general. There isn't a company like APR pushing them either.

        Truly the crappiest gearbox of the modern era.

        What is so bad about it?

        It's not super durable (plenty of reports in various forums of people needing multiple software updates / clutch re-learns to keep the thing in adjustment as it wears out and plenty of people needing transmissions replaced. It's not particularly quick for a dual clutch, the way its programmed is sluggish and unresponsive in all transmission modes and this is made worse by the fact that its shift logic in C mode wants to keep you below 2,000rpm even when you have your foot relatively deep in the throttle.. In S mode, you have the opposite problem: it's usually in the lowest possible gear and is reluctant to upshift even after you've stopped accelerating quickly (other Benz transmissions in C class and higher models are much, much better at reading your driving style and adapting on the fly). There's also an annoying situation where the transmission computer decides it wants to upshift and in the second or two it takes to actually shift, if you decide you want to accelerate and change your throttle position it sometimes ignores you and upshifts anyways. M mode is obviously fine but the non-AMGs like to jump back into automatic shifting mode. I believe the later model years may have fixed this but I know our first model year CLA250s both behave like this. A lot of this is better in the CLA45 AMG but in my opinion, the 45's transmission is still the area where it lags the most compared to its BMW and Audi competition in this segment. Another annoying thing, you have to pull the shift paddles quite a bit before you actually want a shift so you have to pull the paddle long before you approach redline otherwise the car will run into its rev limiter and get stuck there FOREVER while you bang on the upshift paddle before it finally gets its head out of its own ass.

        I work at a shop that owned 3 CLAs, 2 250s and a 45 AMG and we still have one of the 250s. Everybody at the shop despises this transmission and it's one of the biggest reasons I tell everyone to spend the extra money and go for the W205 C class every time I'm asked.

        Well, it sounds like it is terrible based on your experience.

        That sucks. The engine is awesome.

        Yes, the engine is very impressive and the CLA overall is a great car that owners are very happy with. A properly sorted out transmission would drastically improve the driving experience.
