blow off valve ?

Hey guys i own a 01 7.3 powerstroke diesel i am from Ilinois, and i want to put a blow off valve on my turbo diesel ? i did see bov on a diesel jetta but never on a 7.3 truck any recomendations?
I searched here on forums quite a bit and couldn't find anyone that done it.
I know how bov work and what they do but i also know that our trucks don't come with bov, why ??
i wanted to locate the bov on the upper inter cooler pipe, and connect the vac line to the wastegate actuator.
Please point me in right direction thanks in advance.

Adam.

you will need to creating some vaccum which the diesel trucks do not do. if you were to fab and create a blow off valve for a diesel you would find that the valve would never open. if you want that cool woosh sound just buy a nice set of bags

A BOV on our trucks would be simply for the sound effect. If you are looking for that effect, just put an intake on your truck, floor it to build some boost then let off the gas. The more boost you build the louder the "blow off" noise will be

As you know, the blow off relieves excessive boost pressure & is usually found on manual trans gas engine vehicles. On gas engine vehicles, the throttle plate is between the turbo & engine. When your foot comes off the gas pedal, the throttle plate closes between shifts & the BOV vents boost pressure and helps keep the turbo spooled up. IMO the powerstroke engine does not need a BOV because there is no throttle plate. With the diesel engine the fuel is cut out when you lift on the gas pedal.

And there is already a wastegate. If you have a straightpipe exhaust and good intake you WILL hear the noise you're looking for. There is no point to a BOV on a diesel with a fixed vane turbo.

thanks for the input guys, i found what i was hoping to find here and yes i have a straight downpipe which is loud as hell and you can hear the turbo spool up, there is one more thing, i found that there is some kind of line that goes to wastegate to open it would that be a vaccum source of some kind ?

Diesels are in need of blowoff valves, and actually contrary to everyone's belief there is a blow off valve for diesels. People may think its cool when their truck makes that tsh tsh tsh tsh sound when they shift, but thats your turbo going from 150,000 RPM to like 5 RPM in like 2 seconds, aka your compressor wheel wants to explode, this is where blow offs come in, Yes you need vacuum and yes boost is controlled electronically but here is this link below. Its pricey but if your really interested i would say its a good investment. It will save you a couple turbos through out the life of your truck.
