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?
Started ESS...ended CUSTOM!
