the 335i's, twin turbo 6 are pretty stout. i drove one back in 07 when BMW had a cancer event and you got to drive the whole line up. it has a small turbo so there is no lag in the system for sure and i know it will do 140mph easily, i found out the hard way too. but if it's a stock one and you have a modded car that is boosted you should be able to take one easily.
