Bov

[Adz2332]

OK ive been talking about this in a thread in the forced induction but it seems different states have different things that are legall etc... SO

Apart from the standered BOV can you legally change it to anything else? I was told Plumb back ones are legal that true?

Please clear this up for me, what is south australias stance on them...?

[Cubes]

When I spoke to regency Vehicle standards they said you can't run an aftermarket bov regardless if its plumb back or not, he also said I couldn't modify the return pipe or modify the afm to turbo pipe.

BUT.. ring another day and I probably would have received a different response.

so were stuck wid the standered BOV?

thanks, shame i dont live in other states lol

Looks like it.

For myself.. No bov, thin sheet metal plate blocking it off. All looks standard. 4" afm to turbo pipe.

Large afm to turbo pipe reduces the ever so slight drivability/stall issues you get with no bov.

You get better next gear boost response when not running a bov.

doesnt having no BOV ruin ur turbo?

[Cubes]

No. Its a drivability/smoothness/emissions thing.

If your running a big turbo with lots of boost you may encounter your silicon joiners blowing off if you don't run tbolts & have the lip of the pipe flared. Silicon is slippery.

[Adz2332]

Nope.

Its a drivability/smoothness/emissions thing.

oh i thought some one told me no bov hurts the turbo or something... does it make a wooo wooo woooo sound without the bov?

Lol sorry bout the sound affects!

[Cubes]

lol yes the bov manufactures tell you it hurts the turbo. lol

With the stock afm to turbo pipe the dose sound is fairly quietish but with a metal afm to turbo pipe it is quite a bit louder.

Have a read of.... Simon from Nispro.

Also Quiz Shaun @ Boostworx if your worried.

[sinistaGTR]

wuoldnt do can f**k your turno....and you get the ultra gay vl turbo noise

[Cubes]

Says who? The Marketers

I know of a VLT running 12psi thats been running no bov for 270,000km's still on its std origional turbo that even worse... is a journal bearing turbo.

It will be fine. Speak to Shaun if your worried.

[Murry33]

whats all this bulls**t about no bov ruining your turbo lol??

that flutter noise is just air getting chopped up by the blades yeah?

cubes gives good advise, however it does cause stall/drivablity issues, so larger afm is a great idea. which i need to do soon myself!

[Cubes]

Not larger afm.. Larger pipe that resides between the AFM and Turbo.

Help slow down the air a little.

[Murry33]

well that's my next mod then haha, my car keeps stalling on idle

[/2on]

Yeah the whole comp surge wrecking your turbo is a bit of a myth, no ones actually had any proof it does do any damage, and Adz with your BOV question apparently no BOV that can be adjusted is legal regardless of wether its atmo or plumb back.

[andz]

bov gives u the wank factor

chicks and pedestrians love them

thats about it

[Pauly33GTS-t]

yeah but andy u say the same about flutter too and I been telling you that flutter is a product of no bov...

run no bov u get flutter.

[Cubes]

run no bov u get flutter.

+ better boost response when selecting that next gear.

Flutter... also if you run a bov thats too tight.

Some bov's you have to tighten right up so they don't leak on higher boost levels.

[Murry33]

so no bov+large piping between afm to turbo = lots of flutter yeah?

need someone that sells/makes the aftermarket piping, does anyone know of a good place?

cheers

[Pauly33GTS-t]

I doubt it, I have never seen aftermarket pipe for our cars.

I got my stainless steel intake pipe from Shy180 - not sure if he's still a business trader on here though.
