    • 950+ awhp Porsche 991.1 Turbo S with ByDesign XR turbo kit on stock engine internals

      Yet another stout ByDesign XR Porsche 991 3.8 Turbo result here. This 991.1 Turbo S comes hot on the heels of a 991.2 Turbo S making ~890 awhp with the same turbo kit on the same dyno. Even the tuner, M-Engineering, is the same.


      The torque and power curves are works of art:



      Boost reaches 26 psi with methanol injection as well so why is this one so much stronger?

      Maybe the tuner or @SamboTT@ByDesign can help explain it.

      The car is on stock internals and it is unknown if the PDK is upgraded.

      Another strong ByDesign XR result but it would be great to see another dyno used to record output due to issues with World Motorsports correction factors and inconsistency with their Mustang dynamometer.

        Hnnnnng. That is $#@!ing awesome.
        Cant imagine how fast this thing is. Wonder how long the stock motor will last at this level...if its stock PDK it puts the GTR to $#@!ing shame lol. They need fully built transmission at basic bolt ons.
