Illegal

Not warrantable !

[PhatRS]

Unless they have mufflers and exit behind the last rear passenger compartment?

[Joker]

and are under 89db correct

they are classed as an exhaust leek WHICH technically a Atmo. venting BOV is anyway...

Under the db and exiting behind last passenger compartment, wouldn't make it a screamer

This would make it an external wastegate that is quite and legal !

And and Atmo BOV only vents intake charge NOT exhaust gas

everyone knows that bov is for intake.

the bov amendment for the virm is on the same page as exhausts, even comes under the same heading.

depending on where it exits the vehicle and sound, also size of turbo matters here....

The WOF code doesnt go into turbo size etc etc. Just has externally venting equipment necessitating exhaust or otherwise...something along those lines.

once its in the intake its not allowed to leak (past the Filter)

It can be legal, mine is legal and has passed many wof's. You must have a screamer pipe venting out the back of ur car ie like mine a seperate pipe by exhaust. Otherwise it could be classed as an exhaust leak, plus numerous safety reasons it's in ur benefit to do this or at least have the pipe take the hot gasses away from the engine(Don't want leaking oil to catch on fire).

The only issue is the noise, which is the whole point of a screamer for wank factor which is illegal. Yes I have one so not having a crack at you mate. As mine is now a track car Im not too concerned bout the noise(majority of vehicles out there are far louder then my screamer), but if you boot it on the street you are up for noisy exhuast fine and at worse a green sticker.

I dont have proof on me but one of those thing s that came from a W0F inspector (new tard) - but also one of those things they dont ride 'us' on...

[sultan]

then surely my car will fail on this (bov) when it undergoes the certification process shortly

[nztintin]

I've passed multiple wofs and a cert with a vta bov, it's even on my cert papers stating it's aftermarket vent to atmoshphere. It may depend on your certifier, mine was pretty cruisy!

[sultan]

who'd you go to?

[nztintin]

automechanix in tokoroa, he's not the cheapest tho as i found out after the cert.

[Rex_in]

Ive just looked at the VIRM, section 11-1 Exhaust Systems:

there is nothing in this section that relates to any noise being emitted by a VTA BOV,

I also looked under Section 13-1 Engine and Transmission

and there is nothing there that relates to VTA BOV's

but it does state that

"LVV Certification is required for the fitting of a Supercharger or turbocharger as a modification, or the substitution of a Turbo or Wastegate, or the re-chiping of electronic engine control units on turbo cars,"

So any of you guys who have an External wastegate, have swapped your TD04 for a VF22, or had your ecu chipped/reflashed technically need a cert......
