2000 Audi S4 on a Dynojet. Ended up putting down 468 horsepower and 486 ft lbs of torque on 28psi pump gas 93 octane & meth mix. The car had 3 bad coilpacks, as well as a bad Boost leak from the throttle body. Hoping to hit the Dyno again soon with a few fixes & modifications.

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!
