I wouldnt fit a BOV id run no BOV at all you get better cooler noise then and no it doesnt hurt the turbo or engine there are 8 second vl turbos are with no BOVs on them at all

Ok, you obviously don't understand what a BOV does.

It releaves the manifold pressure when you ease off after high load. Without a BOV you put increased stress on the intake manifold and its components. It helps keep things under control allowing everything to work nice and happy....

So no, you can't run sans-BOV on a street car. It is not designed to cope with the increased stress....

thanks for pointing out that pointless nothing

again you dont have to run a BOV if you dont want to if a 8 second vl turbo running 45psi plus can go without running one im sure its not going to cause any problems

What blow off valves would fit the XR6 Turbo? Or Do they all fit? Mainly for the sound they make. I dont have a XR6 T... yet but just looking at things I could do with it when I get one. 

Thanks

Mate top notch one to get is the GFP StealthFX, its a direct replacement for the standard BOV and is adjustable from full vent to full plumb back with 14 settings.

There's one on ebay for sale

Any particular reason why your selling?

Yeah I ran out of room near the BOV to mount my hob switch for my boost guage, so the BOV has to go and the standard one goes back in I couldn't justify having a $550 BOV sitting on the shelf.

Better watch out cause Goose has his eyes on it and he only lives round the corner!

Ahh what a laugh....... Releaves stess on the manifold hey!!!!

Hi Jon

I got a Turbosmart , they make one for the XR6, its the 'Kompact' range, it took about 20 min to install and makes a great sound, it cost $290 and worth every cent

<{POST_SNAPBACK}>

Does that make a loud noise?? I wouldnt mind putting one on but I dont want it loud just subtle...

If you by a new BOV and it plumbs back the same as the factory one, then it will sound no different. If you by one that vents externally then it will be loud as hell, and you will have to find a way to plug up the hole in the intake crossover.

As far as I know the only one I know that fits and can vent externally is the GFB Stealth FX as well as plumb back or both.

Did you actually take the time to read Brian's post?

That's right Adam for drag cars, and I think rally cars as well.

If you keep your foot to the floor in a drag situation, especially where an auto is used, you want to keep the turbo spooling, and don't want any pressure release or boost drop that a BOV may cause... and so it's largely redundant.

But for normal street use, where most people are opening and closing the throttle, the BOV helps protect the turbo compressor, which is desirable.

The 8 sec VL Turbo would be a drag car....not a street car. Probably pulls the motor down and rebuilds it after every drag meet too.

The motor isnt pulled down after each meeting

I know many vl's that run 9's and 10's that drive on the street everyday and dont have a problem my car had never had a BOV on it and never had a problem with it and it has been both manual and auto

My point is you DONT have to run a bov and without it you get better cooler noise and your engine isnt going to die without one

No, you don't HAVE to run one. Its just that by the things you seemed to hold in high esteem in your post, being "better cooler noise" and that "it wont hurt your turbo", indicated to me that you didn't understand why the BOV existed.

Also that you have compared this to (or even mentioned for that matter) a 45psi drag car as an argument for why a <15psi street car shouldn't run a BOV also indicated that you don't exactly understand the physics and reasoning behind why BOV exist for a drivable, tuff street car that has minimal stress on the engine overall...

So my appologies, as obviously you have a doctorate in intake systems and turbine mechanics (yeah....).

Again, my appologies.

So let me rephrase.

If you are running a mild street XR6T then it would be unwise if you chose not to run a Blow Off Valve...

Sorry for trying to help.

Oh, and btw, I didn't specifically mean just the intake manifold in my above post, the specific components that I was refering to would be everything pre throttle body, post turbo.

For ease of explanation I simply coined everything on the intake as the manifold to make life easier, as I didn't reason that he would realise the difference anyways, yes, I shouldn't have assumed this. My bad, I'll make myself clearer next time.

Anyway. Enough of this petty crap, lets just get on the with topic; as it should never have been side-tracked in the first place.

Cheers.

I can vouch for the fact that the stock BOV will happily handle up to 22psi and beyond
