    • Stroked 3.0 liter B5 S4 with RS6 hybrid turbos takes on a bolt on 2013 Shelby GT500 Mustang

      The new 2013 Shelby GT500 is a beast of a car even in stock form. The 5.8 liter aluminum block V8 is rated at 662 horsepower which is no joke for stock and the horsepower rating had to be adjusted upwards by Ford. To the wheels, cars have put down in the ~600 wheel horsepower range stock so this bolt on vehicle is making considerably more than that and likely well into the 6XX wheel range. Its opponent? AudiBoost member 600whp_S4's 3.0 liter B5 S4 with RS6 hybrid turbos.


      This B5 S4 is a quick car having previously taken down a bolt on C6 Z06 on low boost. The car has a VAST tune and modified 2.8 liter V6 heads. He did not state how much boost he was running or what fuel during this run.

      Regardless, it's a good race but the GT500 gets a bit of a jump. The S4 is able to impressively catch and pull despite not having the instant torque of the positive displacement GT500. You can feel @600whp_s4's excitement at the end of the run, congrats on the win. His full build specs are available here.

      Enjoy the video below and perhaps go with honks next time.

        If you're ever out this way for an event, hopefully we can meet and have a go with the cars. Racing can be unpredictable, so who knows what might happen. :-)
