    • Audi S6 with RS7 4.0 TFSI turbo swap and APR tuning runs 10.6@129 in the 1/4 mile

      Swapping RS7 turbos onto the Audi S6 or S7 is the best way to significantly improve the performance. As US customers do not have the option of an RS6 and Audi no longer produces an RS6 sedan it is also a neat way to build your own RS6.


      This S6 features RS7 turbos, APR tuning, and an AMS S6 turbo cooling system.

      The result is a 10.697 @ 129.01:


      RS7's do run slightly quicker and faster. It will be interesting to see if S6's can close that minor gap due to the 4.0 TFSI V8 design differences or even exceed the RS7's performance.

        If it's the same car I'm thinking of, it also has CF inlets. Great time for a heavy sedan!!!

        Pump gas or race fuel? I wonder how long the dual clutch trans will take that kind of power.

        I'm not sure on the fuel and somebody was saying the trans can be upgraded.

        Given the full APR Stage 2 treatment for this car is FIVE GRAND and that gets you a flash tune, downpipes and a transmission tune, I can only imagine what the RS7 turbo upgrade and intercooler upgrade will cost. This may be an instance where just getting the RS7 to begin with might be the better buy.

        Absolutely it is.

        What can you do with a Tesla anyway? Strip out some weight? Yawn...
