I didn't think the size of the turbo had any relationship to how much power per psi it puts out.... Usually size only matters in spool time and max psi possible. each psi should still add a fixed amt of hp, based on compression. The size of the turbo relates to the size of the impaler, and the size of the housing, which relates to the spool time, and possible boost. Please correct me if I'm wrong.
