They exist... they do prevent the bark you get on letting off, especially when shifting if your truck is stick.

The one I can think of costs $700... Yes the turbo bark does put stress on your turbo, but people aren't regularly blowing the 38's to pieces. Besides you probably have a stock turbo, which you can have rebuild for a couple hundred if it does eventually fail.

The reason BOV's are so expensive for diesels is they must be electronic. A regular BOV or Bypass valve on a gas engine works on the pressure wave from closing the throttle plate. Diesel's don't have a throttle plate therefore a regular one does not work, it will do sweet nothing.

Alot of the higher hp 6.4 guys have them on their twin set-ups. Especially those running with a vgt. it keeps that bad boy safe from overspinning.

That's a turbo bark. (0.55 seconds in)


What's happening is all the boost pressure from the intake, intercooler piping, and intercooler is rapidly exiting through your air filter.... in other words the air is going the wrong way.

This causes your turbo wheel to go from spinning really really fast, to almost stop, back and forth until the pressure dissipates. Causes stress on the turbo.....

Will it make it blow up tomorrow? no

. Will a BOV help? yes

Is a $700 BOV worth protecting a turbo worth less than that? hell no. That's why aside from high boost non wastegated builds you don't see them in much use.
