Ok I know a guy with a 2005 S4 that he claims puts out 420 hp at the crank (after mods). He isn't saying what mods he's done but the exhaust is stock sounding.
Are these cars really that fast and does anyone have any stories of running against one? Stock it looks like 0-60 is 5.3. Any chance I could beat him with my stock 06 wrx?
Also what kind of mods would he have to do to get 420 hp? The car has the 4.2 V8 btw.
