Bov Legal In Sa?

[jdmr33]

Hi does anyone know the legal status of blow off valves in south australia?

Give regency a ring.

I did some time ago and was told you are not allowed to touch anything that is concerned with the bov, being; the bov its self, the cross over pipe, the pipe that runs from the bov to the turbo inlet pipe AND the turbo to afm inlet pipe.

Thanks i just imported an r33 gtst and it has a blow off valve which you can hear quite easily i haven't had a chance to look but i assume its after market i wondering am i going to get defected for it should i get another quite one cheers

Even though the skyline std bov is recirc you can still hear it.

Especially if the car runs a pod.

[nos man]

urmmm just remove it and use the air filter for noise!

[Madaz]

yeah its quiet possible as cubes said u have standard BOV and a pod mine is quiet loud without being intrusive

[bixby]

As far as I know, ATMO BOV is illegal due to some air pollution thingy..... My friend got sent to Regency for that.

[Cubes]

Yep the std recirc bov is there for emission reasons.

[MistR33td]

Yeh ive got an R33 Gtst and its got a stock blow off valve and an apexi pod......u can very easily hear the BOV noise, sounds sweet! but yeh its probably a stock BOV coz wen u import ur car and it gets complied dont think defectable mods to ur car are allowed.

yeah, crankcase emissions.

[Cubes]

yeah, crankcase emissions.

More so how it plays with the afm and dumps fuel.

I blocked my bov off when testing if it leaked and found it would pop and fart & occasionally stalling.

Venting the air would play havoc with the air metered even more so.

[nos man]

you're allowed to have plum backs though yeah?

[nisskid]

^^yeh

[Cubes]

I asked regency about aftermarket plumb backs.. I was told no, its part of emissions so I can't touch it.

This was some time ago.. Give Regency a buzz and see what their stand is on it these days.

Just block the std off and enjoy quicker turbo spool and almost zero lag between gear changes.

As mine spools so soon it caused a few driveability issues but nothing I couldn't work around.

[nisskid]

um...a BOV (or recirc. valve) increases response in some cases, yes the air is released and that air does need to be replaced causing lag, but at the same time, the air not being vented without a BOV is forced back towards the turbo going the oposite way to the turbo causing the turbo to slow down quicky and to spool to the turbo up again takes time, creating lag.
