Attention: TDR Forum Junkies 
Went to a open house at PACCAR (parent co. of Kenworth and Peterbuilt) last saturday. Cat had a new engine on display. It had staged turbos on it. The rep said it was to meet EPAs New polution decree. I got my Diesel progress news and there is a article on those engines. They are twin charging there 11-13 and 15L engines. This is a very nice looking setup. I have not checked the Cat site but a guess would be they should have information on them. . It is not just the hyperformance dragracers and sled pullers anymore!!
