bypass valve installation, 5kcstq

[Ken Keith]

I was looking at Eric's site about 5kcstq fixin' up:

Cool stuff.

I eventually saw a picture of a modified michelin man hose, for a 
bypass valve.  I was wondering what other installation methods are 
used to install one.  Are there any other pictures of installations 
online?

Here's the valve page:

They don't have to be installed in the michelin man hose, do they?  
Can't they be before the intercooler?

Also, is there a benefit of having the bypassed air go through the 
intercooler twice?  Is that what it's doing in this example?

Thanks,

Ken
