I know of 2 other boxster owners who have desnorked and then subsequently resnorked. One complained of getting a slight hesitation/stumble at around 4K rpms after desnorking, and another resnorked because he thought he felt a slight power decrease after desnorking. I have absolutely no proof of this theory, but my thought is that the end of the snork tube has a curved opening which acts like a venturi, sucking in air at a higher rate when at high speeds, and thus shapes the air for better air flow as it hits the airbox.
I am thinking that a good real world test would be to run a car that is not desnorked from 5-100mph (on the road, not on a dyno where there is no true simulation of airflow as you hit varying speeds up to 100mph) and time it, and then do the same test after desnorking the car. Anyone up for a little test run?
