Did you guys notice the JCB diesel streamliner using all the fancy

I thought that diesels don't have to run with extremely low  
compression ratio when running high boost.  I mean, they've got to  
have the CR high for starting and when the turbo isn't spooled up, and  
anyway, they run by ignition because of compression making heat.   
Strong innards are required -- that's how they hold together.

Clem Roberts (that was his name, right) ran his Ford p/u at Maxton  
(and once at Bonneville) with sequential turbos making 120# boost by  
the time the charge air got to the intake valve.  It was transmission  
troubles that did him in.
