I think the ARC intake scoop addition would have to do something similar in terms of getting more air in?
That was on a WRX website, and in an STi scoop I can see the merits of the design, however 100% is a big expectation...
ARC intake scoop addition would help, it increaseses the charge intake gap from 30mm to 35mm, and it protrudes further forwards which would definitely aid in increasing the intake charge velocity. However turbulence is something that is a little hard to measure - I sold my wind tunnel before I bought the Liberty - and gainsare going to be very difficult to measure.
