I'll have my Typhoon at the track in April. However, my tune will be modified heavily (tweak, dp's, tstat and 3 bar) since I got my 13.006 with the stock air box so it won't be a very good comparison. We need somebody to run stock airbox vs. Typhoon/Air Raid. If I'm not too lazy, I might try a couple runs with each under identical circumstances.
To those who can hear their turbos spool up, is it that kind of crackling swoosh I hear around 1500-1800 rpms under acceleration or is my intake diverter vibrating?
