Roots blowers obviously get on boost sooner, but really, if you look at the trade offs it really does not make sense in a non V engine config.
Speaking of which, how do you really plan to put a roots blower on a flat 4?

OEM no, aftermarket yes. But again, I think were debating the
perception of lag rather than the actual lag...
What's wrong with a roots blower on a flat 4? In fact, I'd say for a small displacement engine that will tend to have limited low speed grunt, for a daily driver or autox car a roots blower is probably a better choice.
The major lament about roots blowers on a small motor is the
limited top end, not the low speed torque.
I'm not knocking turbos, but they simply have different flow characteristics than roots blowers, and what will best suit an individual depends on their personal preferences and style of driving.
EDIT: Oh, wait...
flat 4... good point. I thought there were a few production set ups like that tho -- no?
