This is really interesting.  There are lots of posts about this on Ubuntu Forums.  Look here:

Several of us are getting low quality cbr's no matter what we do with sound juicer.  Jorns, however, replied that it worked just fine for him and he was able to get genuine vbr files.  He writes:

I tried the above mentioned sentence:

audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr=4 vbr-
quality=0 vbr-min-bitrate=160 vbr-max-bitrate=192 ! xingmux ! id3v2mux

and changed 192 with 256. For me it worked like a charm, it now makes VBR mp3's between 160-256 kbps.
My software is the same, Ubuntu 7.10 and Sound Juicer 2.20.1

So what makes the difference here?  Is there some kind of hardware variable?  Is that possible?  I'm using an HP Pavillion dv4000.  What about you other guys who are unable to get soundjuicer to properly juice? (BTW, I'm using Gutsy with Sound Juicer 2.20.1.)

I've had the same experience as Cliff Hall; however I'm using
SoundJuicer 2.22 with Ubuntu 8.04 (beta).

The xingmux parameter makes no difference to how the CD rips--I still
end up with 128 cbr files instead of 160-192 vbr or 160-256 vbr :-(
