I was just looking at DLSJ5's numbers regarding his SC'd E9X M3..
I was like damn, mid 7's is amazingly fast.
Then, i ran upon this..

6.95 60-130 on a 335i still running stock turbos.
Now don't get me wrong, yeah he did use NOS and meth but honestly, spending 13K for a SC kit and 4K for exhaust and etc. etc.
I am a little surprised at what those N54's can do.
