    • 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.

        From 63Xwhp to 59Xwhp, depending on the dyno,humidity etc.

        Fords claim of 662crank hp is rated at 6500rpm on 91 octane, but car can go up to 7000rpm so if you also put 93 octane into the mix, its pretty safe to say that, it has 700 crank horsepower right out of the box.

        Actual races involve other things than just how much power you have, otherwise we could just all bench race and declare the highest HP car the winner! Thankfully people still line up their cars and have a go, and cars like mine have a chance of actually winning. :-) Long live The Silver Bullet!

        Nice kill. Are you in California? If so sign up for the No Fly Zone 3, 1/2 mile roll racing at Minter Field Airport near Bakersfield. I would like to race your Audi with my C6 ZO6.
