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.
