OK boys and girls, I've just been out in Mazzy'z S3, and had a 10-15 minute blast in it. I can confim it's quicker than my AmD stage1, not only in a straight line, but it feels like it handles better than mine on the new coilovers. 1st test was to hit 60mph in 2nd gear, I tried mine earlier on in the day, it can't go past 60 on the clock hitting the rev limiter in second, his car does around 63/4, it revs to approx 7.5k into the red bit on the tacho, as for accuracy of the speedo, I'll let you guys debate that! The car does over 60mph in 2nd as far as i'm concerned.
Performance wise it's certainly quick, feels a good 30lb's torque over mine in the midrange department, turbo spoolup is much quicker and responsive, and it's pretty loud over the standard exhaust. You can hear the turbo spin up more aggresively and harder than it is in my car.
I couldn't find any Evo's or RS6's to challenge in my testdrive, I would have thought if you caught one off boost, then there is a chance you could keep one behind you upto the point where they are just getting started, and you've run out of road.
My conclusion is that it's a quick car, not quiet as quick as an RS6 or EVO of course, but it's usable as a day to day car, infact, it drives like how Glenn describes his original S3, where the torque goes from literally nothing to boom!, in an instant, I'm still impressed, as it's running the same turbo as mine!
