Tom, it most certainly doesn't run out of breath. Hehe, I don't mind it being a little flat chested. It just makes her more aero dynamic! LOL
I'm at the minimum pulley size, but like I stated before there is something restricting my maximum boost becuase after the last pulley change I didn't see any increase at all even dropping what would equal about 2 full pulley sizes or should be about a 3-4lb increase. I'm pretty sure I'm limited by the 500 cfm cooler right now as the max flow of the S/C is 800 CFM which I should be pushing close to since I'm spinning it up to max impeller seed by the time I run to 7500 rpms.
