B5 S4 with 3.0 liter stroker, RS6 hybrid turbos, built heads, and VAST tune versus bolt on C6 Z06 from a roll
Nice race here with a strong B5 S4 going up against a bolt on C6 Z06. The Z06 is a quick car in stock form and this particular car is modified with bolt ons including an intake, tune, and full exhaust including headers. Depending on how aggressive the tune is and the fuel it is running the C6 Z06 can be putting out in the ~500 wheel horsepower range on a dynojet. Definitely a stout car on the highway especially with its fairly light curb weight.
The B5 S4 belongs to AudiBoost member @600whp S4
. He has stroked the 2.7 liter bi-turbo V6 to 3.0 liters, has RS6 hybrid turbos, built 2.8 heads, and a VAST tune. The current tune is a bit rich with 10:1 AFR and he was running fairly low boost at 20 psi on E85. So, he has more in it but considering the outcome the car is already pretty vast.
