That video is of a Jetta 1.8T but lets say you're in 3rd doing 25mph and you put your foot down and let go, it will make that noise at around 2k-2.5

 

do the stock airbox mod and you should be able to hear it

 

Wello honestly i was trying to find something that will be loud at high rpm's but not so loud for normal driving . . . Am i asking to much of a diverter valve?

 

u want what to be loud? the turbo spooling or the "psshh" sound?

 

The little psh sound. Turbo spooling would be nice too.

 

dv has nothing to do with turbo spooling. get an intake if you wana hear that. as for the "psh" sound it all depends on how much air the turbo is releasing. the closer you get to redlining it and the more throttle your giving it the louder the sound is gona be. so if you shift between 2-3k and are only giving it half throttle the sound isn't gona be as loud. however if you just mat it and shift at a higher rpm it will be louder. a k03 will never be that loud tho

 

OK, so, i checked today and i do have a red line next to the T on the back. What does that mean?

 

the noise isnt gunna be that loud unless your getting on it man, its all about how much air has to be let out.. so if your cruising around town not really building boost its not gunna be loud at all, you might barely be able to hear it, but all you have to so id get on it and shift and you will hear it

Im pretty sure thats the sports package but not sure, but def get rid of that springfield acura sticker, it looks bad not to mention you drive an audi. (unless your dad owns the dealership, then its understandable.)
