lots of variables. he was on semi slick tyres. he removed all the seats. he has uprated suspension so less lift on acceleration, hence more grip.
4wd suffers more transmission losses than fwd, hence why the S3's get really good 60ft times, but the ed30's get much higher terminal speeds.
also if you have 325hp and he has 350Hp. that doesnt just equate to a 25hp deficit. he might have that higher output for a longer amount of revs, he might also have more torque, boost might come in earlier and hold on for longer. He has DSG, do you.
he also races cars as well, so he'll have a really handy right foot.
there are alot of variables to take into consideration.
