My Ride: Supercharged 330i
interesting thought, what's the actual size difference between the stock and the 6.8"? I have to be careful going larger on my pulley because the 11 psi pulley is only seeing 5 psi of boostStill scratching my head over that one. I knew it would drop after porting and the larger TB but that was surprising but works out great for the project.

I would be interested in the damper for the ability to rev higher with the turbo (of course I'd upgrade lifters as well). What's the down side to the ATI?
