I love my converted 1.9TD Westfalia with the exception of one thing - the
whistle of the turbo charger.  What have other people done for the air box
on their turbo vans?

My intake system is a very simple setup.  It consists of a 2.0" piece of
muffler tubing that is bent at 90 degrees the end that attaches to the turbo
charger was reduced to 1 7/8" to mate up with the turbo inlet - I used some
hightemp silicon hose and stainless camps to mate the turbo to the pipe.
The other end of the pipe was enlarged to 2 1/4" so I could fasten a cone
style K+N filter to it.  This filter sits in the area behind the driver side
tale light and there is a piece of fiber glass isolating this chamber for
the heat of the engine compartment so the K+N can only draw cold outside
air.

It idle, things are good, inside is quiet and if you stick your ear next to
the driver side intake vent you can hear a slight whistle from the turbo.
One you get this thing on the road it is a totally different story.  That
turbo is very loud in side the vehicle - especially a part boost.

What have people done to keep the noise levels down?  I like that whistle of
power but this is a bit too much for me!
