GEN 2 bov block off plate

[Biggwrm]

So you are removing the BOV? That doesnt make sense.

In a turbo vehicle, under load, the throttle plate is open and the turbos pressurize the intake tract. If you let off, the turbos dont instantly stop spinning, nor would you want them to, instead the BOV opens and vents the pressure when the throttle plate closes, under load again the bov shuts and the system re-pressurizes as the throttle plate opens.

Without a BOV you will have pressure spikes in the intake tract, and you will have reverse flow through the turbo which cause damage.

Why would you want to do this?

side question, for my own knowledge... My 97 powerstroke, doesnt have wastegates or bovs. Is diesel just another animal? Curious why they dont suffer the same, maybe they do..
Figured someone on here had a quick answer.

I asked if someone tried if u can't read properly [emoji6]

To answer your question, no! Nobody has tried this.

 

[MEATSWORD]

Yeah,that's not the way it works. At least not for long.

You do realize that they specifically make BOV’s that make these sounds. They were all over in Japan 10 years ago when I was there. If you want the sound track one down

Interesting! Would definitely try it if I can find one

If you stuff a sock in the intake it helps muffle the sounds. Good for a few hundred ft.lb of torque.

Removing the BOV completely is a BAD idea. Closed-throttle surge may not be as bad as open-throttle surge but it will still cause damage.

Going VTA may not be great for the truck either - I don't know enough about the Raptor to say for sure. The 2.3L Mazdaspeed engine (EcoBoost predecessor) tuning was based primarily on mass air flow. If that's also the case for the Raptor, switching to VTA will cause it to run very rich momentarily any time the BOV opens. This isn't necessarily "bad" for the engine but it could contribute to issues developing long-term. It can also cause some hesitation if you let off and then immediately get back on the gas.
I run turbosmart 50/50 BOV's in my high power cars. At lower boost it recirculates everything. VTA only happens when the recirc is too much of a restriction. It still sounds good and the air that does get recirc'd helps a lot with the rich condition.

Your powerstroke doesn't have a throttle body either - power is managed by how much fuel is injected. When you let off, fuel is cut but the pressurized air continues to flow through the engine so surge is not an issue.
Some newer diesel engines do have throttle bodies but, as far as I know, they're only used for improved emissions and are not required for normal operation like in a gas engine.

Atleast nobody thats going to ad

Ahhh got it now. First diesel .

Ok turbosmart... make a 50/50 EM bov now.. I’ll return this one. I had a 50/50 on my audi, same thing. It needed to have some air flowing back into the intake or it would throw codes. But still gave the sound.

I do admit I thought I lost a lil response going to the vta mod, tho haven’t heard anyone else complain.

It does not have a BOV because it does not need one. There is no throttle body. Power is controlled through fuel metering. Diesels always run lean because of this.

Anyone tried bov block off plate for the flutter sound? and do they throw CEL codes ?

Might sound similar

My God In Heaven. This is the dumbest thing I have ever heard of. That Goat Banging be giving you brain damage!

Well damn.. now i gotta find a VTA tune
