<VV> turbocharger cooling

[Bryan Blackwell]

Hi Frank,

Be aware that the VNT-25 used a plain bearing, much like a Corvair  
turbo.  In that design, it's essentially the same bearing with the  
addition of a water jacket and they can indeed be used without the  
water cooling, assuming you take care of the turbo bearing by not  
shutting it down hot and changing the oil.  The ball bearing turbos  
are different, which was the point Frank P was trying to make, I think.
