The Beast is Back - ARD Audi S4 puts down 591 WHP on E85!
The beast is back! See how the new setup performs on the Dyno with E85: - Twin GT28RS turbochargers with 68mm FP HTA compressor wheels - 4'' custom Exhaust - Fuel Lab 1300HP external pump - 1000cc EV14 injectors - Tilton twin disk clutch. The S4 now puts down 591whp at just 28 psi tapering to 24 psi on a baseline file without any water/meth injection activated. Wonder what it will do at 30+ psi? Stay tuned for more videos!
