They are necessary in gas engines to blow off boost after you let out on the throttle.
Diesels have no need to blow off boost.

Yeah, I think he means BOV.

Although some people do put them on diesels to keep their oversized chargers from surgeing when they let out on the throttle

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
Simpler=Better

But it would sound cool you would just need to find a throttle actuated vacuum switch. My old 1980 300sd had a vacuum switch that controlled vacuum to the transmission. IE full vacuum with no throttle and 0 vacuum at full throttle. On that car it was on top of the injection pump and hooked in to the linkage. It basically made vacuum act like it would on a gas engine with an open or closed throttle plate being that the diesel has a vacuum pump that is constant.

Wouldn't do anything performance wise besides save your turbo if your having severe bark or surge issues when you let out on the throttle.
They do sound cool though

I could see it being very useful if you where using compound turbos or supercharger turbo set up

04-19-2013, 10:36 AM #11It still should not be nearly as bad as a gas car since there is no throttle plate getting slammed closed. unless the engine can loose all of its rpm very very quickly. It should just gently slow down as the rpm lowers as it looses back pressure from the exhaust.

IT'S USELESS cause youre loosing boost but the point to build it
on/off
cause i love the sound of BOV )))

My buddies 5.9 cummins needs a BOV. His 66mm charger surges like CRAZY when he lets off the throttle. Slow or fast.
