LOL.. nice 1... umm... i was actually thinking about this. The reason for a whine or small noise of the turbo is because of the filter. But if you are going to take off the sound filter, you have to get a new DV (blow off valve).. so that you dont kill your everything basically. But yes you can do a lot to make it louder.. easiest and best way is ECU... the ECU is my next mod. I think im sticking with GIAC ... cus if you ever plan on upgrading to the K04 turbo.. or the PES t-28... they give you 200 bucks back for your GIAC chip. Another thing you can do if you really want sound is.... umm.... make a cd with revving noises and turbo blow offs on it...lol.... people will think you have a supra... and then my son you shall be the Ultimate Rice!

no. no no no. and here is why they are not to be used on our cars.
by ImolaS4
The Audi turbo system is a closed loop system by which all unused boost that is spooled during off throttle and gear shifts must be re-routed within the system; it cannot be vented to the atmosphere due to the dependence on the MAF and ECU to properly read and interpret air flow dynamics within the intake tract. Therefore BOV's (Blow-Off Valves) are not used because they create a rich air/fuel condition (i.e. less air to fuel ratio) which will damage the catalytic converter, create soot on the exhaust pipes, and cause occasional misfiring (due to the purged air) which will result in ECU miscalculated timing adjustments and other errors.
For Audi closed loop turbo systems, a BPV (By-Pass Valve) or DV (Diverter Valve) is needed to recirculate the purged air and keep it within the intake tract.

BOV is a DV.. isnt it?.... Blow off Valve... Diverter Valve... there are plenty of DVs... go to audi-stuff.com lots of good dvs there i think.
