Drivetrain is my main concern, double the half-shafts of a 335i and no telling what the transfer case can take. Seems like the hard-launches will spell doom for the half-shafts just based on what RWD cars are doing with good drag radials and a sticky track.

Highest WHP 335xi that I know of was Firepoule on youtube (bobvader on here), I want to say he was ~450whp. Not sure what drvetrain stuff he has replaced if anything but I've always been told the 450whp+ mark is where the repairs start to flood in for 335i or 335xi.
