OEM airbox on mine two. Adaptor bracket to shuffle it across about two inches outboard. Quiet as a mouse. Pain to change the filter, but always was anyway.

 

A pain just like the oil filter, the fuel filter and anything else on the car!

Golf R/Audi S3 on mine complete with the quarter wave/resonator pipe. From a dim memory of the last time I drove it three years ago it dampened things down nicely even with the 2.9" pulley. But did make you realise even more what a characterless noise the Tullet 3.0" system makes.

I replaced the open foam pipercross with an ITG stab bucket and it’s got much less whine unless you really pin the throttle.

The sc is unlikely to be the dB issue though, at those volumes the sc would damage your hearing. What exhaust do you have?

the standard saab air box was a very good and cheap option to lower the noise a lot. 

 

worth a look at.

Put me down for one Joe, hopefully it will tone down the supercharger without the risk of tripping the noise meters at Bedford and other circuits!

I'm running a decat tullet 2.5" exhaust - I have no problems on static noise testing.

I wonder if an inlet resonator box would cut this noise out?

 

The originale US supercharged engine runs a resonator in the inlet tract, just for noise silencing... :sleep:

She's ace although the teenage bit can wait.  Hopefully I'll get her out canoeing so she can take her anger out on the water otherwise she's her mums!

 

No filter for me, I already have one!
