    • McChip-DKR builds a 909 horsepower GLE63 AMG with upgraded turbos and forged M157 V8 internals

      A 909 horsepower 5300+ pound SUV with a 5.5 liter twin turbo V8? Yeah, that is the kind of thing BenzBoost is into. McChip-DKR in Germany decided to build what they call an MC900 GLE63 AMG Coupe.


      What was done to hit that 900+ horsepower figure? This:

      • Performance upgrade mcchip-dkr Stage 5 (MC900) 909 hp / 1096 Nm
      • mcchip-dkr software
      • V-Max removal
      • Transmission software upgrade
      • mcpipes exhaust manifold and exhaust system with sport catalysts
      • Upgrade turbocharger
      • High-performance H-shaft con rods incl. bearing shells
      • High-performance main bearing shells
      • High-performance pistons

      Custom tuning, upgraded turbos, and forged pistons/rods for the M157. They say only the transmission tuning software is changed which is surprising considering one would expect 808+ lb-ft of torque to require some hardware upgrades in the transmission.


      There is a crank dynograph in the video below but no acceleration data is provided in the video or anything showing what it can really do. One would think this is an easy 10-second GLE63.

      Badass, no doubt.

        Even though Mcchip-Dkr sounds like a weird name, they do seem to do quality work and know what they are doing.

        Only 3 cylinders per bank feeding the turbos? Wonder why they did that.

        My same thought.

        I wonder if it’s for exhaust sound? So that the sound waves are able to avoid the turbine. I am assuming three cylinders produce more than enough exhaust to spin the turbine, so if you’re MBZ, why not?

        For some reason it’s not that unsual with benzes. Wondering what would be tuning like. The loads for the free cylinders are going to be totally different.

        Wow that is strange...although I’m sure it’s certainly not necessary to have all 4 cylinders spool the turbo. When you think about how it used to be...900-1000 hp used to require a turbo the size of a small pumpkin and 40 PSI of boost...now you get there with two turbos you can hold in your hand and about half that boost pressure, on some engines. And the turbos are small enough that they spool relatively quickly.

        But yeah the tuning has to be strange...is this how the OEM M157 manifolds look too? I don’t think so...

        The OEM M157 manifolds use all 4 cylinders to feed the turbo. If you look at this manifold they took the runner of the cylinder farthest of the turbo and moved it over in place of the 3rd cylinder runner(you can see the weld). Then they just connected the last cylinder to the downpipe. Very unusual.
