Hello,

I pulled the silencer ring out of my turbo the other day. I opened the stock air filter box so I could get an idea of the turbo noise I was going to hear. It made hardly any noise however I could hear a little deeper rumble from the engine sucking air. I was under the impression that I would hear alot of turbo noise. Does it matter that I have stock exhaust? I reved the engine up and tried holding a fast idle, then I put it in gear and brake torqued it and really didn't hear much from the turbo. Is this normal?

Thanks.

Your not going to hear much with stock exhaust and a stock airbox with paper filter whether or not the cover is off

 

Go and get yourself a BHAF and straight pipe your exhaust. Then you'll hear that baby sing.

 

True, you can hear it better with an better exhaust and intake.

 

helps also if ya gut the baffle tube in the inlet between the filterbox and the turbo.... theres about two pounds of plastic trying to keep that turbo quiet.

 

You won't hear it just revving the engine in the driveway,
you have to have it under load, over 10psi boost, driving down the road,
climbing a grade really let's it whistle.

No baffle in the 2nd gen's, came to be in the 3rd gens.

I don't think that ribbed tube help either though. I wonder if anyone makes a smooth tube that can go in its place.

 

You got to have boost to get it to sing.Run it up to about 70 with the overdrive off instant
singing.

 

It'll sound like your at an opera, the HUGE fat lady singing her dunlop stomach out...
