Turbocharger Question Non-LSR

[Dick J <lsr_man@yahoo.com>]

A local dirt tracker that I know, who is also a truck driver, happened to pull 
up next to me in his big rig on the way home, and tried to demonstrate his 
racing technique.  I couldn't get over the whir of that big turbo right next to 
my driver's window as he pushed it to the max.
   
  Just exactly how high do those great big turbos spin?  I've seen the one on 
his  rig and it must be a foot in diameter.
