I wouldn't necessarily agree with that conclusion. The dirt could have been caused by high pressure at the front of the car ramming air through the newmission, not necessarily that there's vacuum pulling air through it into the airbox. It also doesn't surprise me that there's no dirt where the new holes are because, if there is indeed vacuum pulling air in through those holes, that air is being pulled from a relatively clean area (under hood). It's also a possibility that there is actually pressure from the newmission tube blowing OUT of the new holes at speed.
