Diesels don't need a BOV. Something to do with petrol engines having a higher boost pressure (Correct me if I'm wrong :P) therefore diesels don't usually have them. They also don't provide any performance gains for diesel engines.

Diesels don't have a wastegate - this article is quite good - http://www.dieselarmy.com/engine-tec...ff-valves-bov/

A blow off valve or dump valve is used on a turbo PETROL engine. A petrol engine has a throttle butterfly valve which blocks the inlet when you take your foot off the accelerator. When you do this, the pressurized air from the turbo has nowhere to go. Without a blow off valve, the back pressure can cause the turbo compressor to slow or stall. When you try to accelerate again, the turbo has to spin up to speed again which creates lag or a flat spot.

With a blow off valve fitted, when the throttle is closed, the blow off valve vents the boosted air so that the turbo compressor does not slow or stall so that when you press the accelerator again, the blow off valve closes and the boost is there instantly because the compressor is still spinning fast.

A diesel engine doesn't have a throttle butterfly valve to restrict the inlet when you take your foot off the accelerator, so the turbo does not slow/stall anyway.

When my car was on the dyno road this a.m. I almost needed a dump valve when I heard my diesel revving!!
