Out of curiosity I took a couple hair dryers and timed how long each took to fill a 30 gal. garbage bag. Both took about 10 seconds. That's *roughly* 20 g/s. Looking at the presure drop chart that AWE has for the stock, RS4, and AWE IC's, the pressure drop around 2000 rpm is minimal, and fairly equal for all three. A log I have of MAF shows around 2000 rpm the g/s is about 20. Just trying to get an idea here on pressure drop, I don't think at the flow rate the hair dryer test used that pressure drop would have been significant enough between the IC's to make a difference in the end results. Another thing to be mindful of though.
