It has a larger exhaust housing that allows for egt’s to stay down without a wastegate.I have always been curious about the lack of a waste gate in the vans as well. I thought they were a mandatory by design of a turbo to prevent (i Guess) it would be over pressure or over speed RPM of the turbo? What makes it possible for the vans to not have them? Can I guess it has to do with the other thing I have heard about the vans being "de-tuned" and THAT was done because there was an inability to provide the necessary amount of cooling air flow around the engine? So because the engine has been tuned down I guess it just isn't possible for it to develop enough EGP to over spool the turbo? Therefore no WG needed?
