no, the turbine wheel of some turbo's at full boost can exceed 200k rpms. even small holset's spin around 140k, so i would imagine the k03 in somewhere in that area

 

i totally misread that. I was thinking engine not turbo.... lol. Shouldnt read and watch Orange Bowl i guess

 

Damn I have never heard of the 200k figure, biggest ive ever heard of a turbos rpm was 80k.[>:]

 

Compared to 2003 Saab 9-3, i can't hear anything. In the Saab, i could definetely hear it when the window was down. WIth the Audi, since the engine seems louder, i wanna say like a diesel, it is really hard to hear. Even in my brothers GTI it is hard to notice as well.

 

Before my mods, I could never hear my K03S spool, but if I hammered it to 3k and shoved the clutch pedal to the floor right at that point, I could hear the DV. Once again, could never hear the turbo spool. This was 2 weeks ago, before the chip/k&n/swiss cheese mod.

 

I can hear my turbo. I have a 2003 b6 1.8t i can hear it well alot actually. dunno maybe my car is just werid or something is wrong. Thats usually the case.

 

'04 1.8 A4 - 100% stock - I can hear my turbo struggling tohelp those 171 horses gallop.

 

Funny your should bring up a Saab. I have a new 9-3 aero with the 2 liter turbo. It's my daily driver. I was looking at buying an Audi 1.8t as a donor car for my swap this spring, and when I drove THAT, compared to the stock Saab I drove to the guy's house, I could hear NO turbo on the 1.8t. my Saab is notably louder...

I think some people are confusing intake sound (which I clearly heard on stock airbox) with a wound up turbo.

PS - didn't buy the 1.8t, had low compression and high miles... the search continues...

 

When i drove all the "stock" 1.8T's at work i really couldn't hear the turbo on the manual cars, i could hear it a lot better on the automatic models, probably because it has a lot more load.

 

I could hear it very faintly, but I have the 170 hp B5. and it was at low rpm in first and second or when I was on the freeway windows up and i floored it staying in fifth gear in between songs.
