B5 Audi S4 quattro VAST Stage 3 FrankenTurbo Borla 0-60 mph AWD Launch Control & Drift...
A video compilation demonstrating the 2-step "launch control" feature of my custom VAST performance Stage 3 Frankenturbo tune. When the vehicle is stopped, the rev limit is set at 4,400 RPM for consistent launching. While holding this RPM, the turbos can produce up to about 6 psi with no load. With this setup, 0-60 mph times in the high 3's are obtainable with a quick 1-2 shift. The S4 also has piggie downpipes and a Borla single 3 inch Exhaust system. Some bonus footage of a coworker who had never ridden in a semi-fast car before is also included. :-) *edit* Unfortunately the girl in this video has passed away of Cystic Fibrosis (4/20/2013). RIP. She was a wonderful girl and will be missed by many. Enjoy!

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!

Took my B5 S4 Avant to the GMG Dyno the other day in Santa Ana, CA (January 11, 2012)... They run a very conservative Mustang Dyno, that they've proven (thousands of runs on both Dynos with same cars and at the same temps, etc) runs 13% lower than the SAE Dynojet industry standards.
