Diesels dont have a use for them at all. You dont have a throttle body. The excess air comes back out the intake when the turbo slows down.. thats the whoosh you hear. no big deal.

not trying to bash but.....
i was told that those of us with the manuals put a lot more stress on the turbo each time we shift at the higher rpms
maybe someone can elaborate on this

I dont see the point... but because I'm feeling helpful.

Your best bet for a BOV would be from the place where BOV's are prevelent, the import world. Some of the best companies for BOV's would be Greddy/Trust, HKS, and Tial.

You're gonna have to fab it up yoruself, unless someone makes a BOV kit for the PSD. Also, it might not work how ya want it unless you have a manual tranny. If you have an auto, you'd have to just kinda rev up and let off the throttle to get the effect

the whoosh sound is not a good sound i thought... its called turbo surge which after prolonged use can shorten the life of your turbo, for that our trucks have wastegates. if are you looking for better performance out of your turbo you might try a better wastegate that doesn't open so early. also if you want a cool sound straight pipe your exhaust, the turbo whistle will put a smile on your face.

I am an import guy at heart and in reality the only reason to buy a BOV is when you NEED one. These trucks don't need them, much as Audis don't (Although some douchers put them on). Many factory cars have bypass valves, that work in a similar manner, but for somebody to spend the money on something just to draw attention to themselves that is otherwise pointless is rather idiotic to myself.

Yes you can put a BOV onto your truck. And YES in some circumstances it will help extend the life of your turbo.

With more modified trucks, with modded (IE different than stock) turbo's, they can experience compressor surge. For instance you go WOT making 30psi of boost, you suddenly let off and you here the woooooosh woooosh wooosh woosh wosh sound. That is NOT good for the turbo, and in that case a BOV will help.

But for a stock or mild truck you dont need one.

The wastegate is to control boost. They went to that for a smaller exhaust housing to help make boost quicker (vs a OBS PSD with a non gated turbo) to help with emmisions. The wastegate is used to help the turbo to not overspeed, creating high inlet temperatures, and shortening its life. The wastgate has nothing to do with compressor surge, that is the compressor side of the turbo (cold side). Wastegate is the turbine side (hot side).
