    • AMR Performance tuned M275 Turbo runs 11.7@119.43 1/4 mile with 0-60 in 3.39

      AMR Performance tuning expertise on the M276 Turbo Mercedes-Benz platform just continues to shine. This W205 C43 AMG 4Matic belongs to BenzBoost member @11SecC43 and most of you should be familiar with the car and its performance.


      Well, he managed to improve his fastest pass to 119.43 miles per hour which makes this the fastest pass to date for a flash tuned M276 turbo:


      That is with AMR tuning on the factory turbochargers. There are other modifications of course:

      -AMR STAGE 2 (RV3.1): http://shop.amrperformance.com
      -AWE TRACK EXHAUST
      -MagnaFlow Universal Spun Converters 53956:
      -WEISTEC 1500 Degree Jet Hot Coated Down Pipes: http://weistec.com/
      -WEISTEC Blow off Valve Adaptors
      -OZ Racing 18x8 UltraLegerra Wheels
      -Michelin Pilot Sport 4S Tires

      0-60 for this 4Matic Benz on street tires is 3.39 seconds;


      The question now is, when will we see C43 M276 DEL30 turbo motors with upgraded turbochargers on the strip?

        Wanted to see if I could back up the 3.3 0-60 I did last year.

        Did this after I got the car out of the garage this year.

        DA was 750' @ 49 degrees F (DA shown on Dragy is incorrect - the elevation is correct)

        Love these cars.

        I have seen others that have run a bit faster than what i ran. They are at sea level though, I am at 1200'. Which can equate to about 2 tenths when you factor in power loss from altitude.

        I haven't seen a faster posted slip?

        I have seen a slip on instagram and facebook. claiming 11.5's at 121 with only a JB4.. how true that is, i do not know.

        I try to provide a slip and video footage so there is no question. Either way regardless of who ran what, these are truly capable cars.

        I have also heard that AMR has still been diligently working on furthering the stock turbo tune with a potential future update. I was told that this update will be beyond RV 3.1 and should yield better 0-60 results as well as better quarter mile results. What those may be, we will have to wait and see.

        To explain this a bit for those that may not be aware. The factory tuning capabilities of the 43's ECU seem to be capped at 20 Psi... which means tuning beyond that was not possible. This was also the reason for the lengthy wait for after market turbos and the poor results of the turbo testing. IE 60-70 whp more than just a tune.

        With that being said AMR informed me that they have cracked the MAP sensor tuning issue and they feel confident that this will not only improve performance for just a tune customers as well as significantly improve performance for after market turbo customers.

        The future looks very bright for this platform

        Let me throw in my 2 cents here.

        Lets say AMR's new tune for factory turbos can propel this platform to 11.5's - 11.4's

        I am currently not aware of anyone running a Killer Chiller with just a tune on this platform.

        Add a killer chiller to that 11.4 ... I have watched videos on Youtube at length discussing the power gains from using a killer chiller. Some people claiming up to 5 mph with just the KC install. With turbo charged cars like ours and our very small inter-cooler I have a feeling a killer chiller could yield amazing results.

        We could very well see a 10.9 out of a C43 with just a tune and a killer chiller. The killer chiller is going to dramatically improve torque for a better 60 foot as well as top end mph. If not a 10.9 it would be darn close to 11 flats i am sure.

        I see the potential of this platform in stock form and it is amazing. That is if the transmission, axles and rear end withstand all of that extra power. Very excited about what the future may hold for these vehicles.

        Edited to reflect this is the fastest flash tuned pass.
