Flutter is caused by the lack of a BOV. Theres another 11ty billion page debate thread on whether its dangerous or not.

true, but a BOV that is too tight will not open under low boost situations and give you flutter, however it will open when you are on full boost

I hate it when people come in and just say go with stock, whats wrong with personalizing your cars sound??? Yes stock may be fine but that doesn't mean he cant get something that sounds different.

Some people don't like blow off valves and that's their preference but they shouldn't shoot down someone wanting one.

If your wanting a decent basic blow off sound with flutter down low revs id recommend the Greddy RS or the new RZ.

Really good bovs and you can tighten it to what suites your preference or plumb it back if you want.

Ah ok, I hadnt heard of doing it like that.

I got defected for BOV VTA a couple of months ago around the corner from the erd head office :happy: should I have contested it?

OP: I have a Tial 50mm sounds good just a nice quick exiting of air no silly putchuu chu cheeeee ft ft chu

If your car is stock why do you want to chang it?

Thats funny Anna copped a atmo bov defect in the sil80 just around the corner from ERD too, they must all sit at Yatala Pies and wait!

dude there messing with you

the flutter although it sounds great it actualy doing damage to you turbo!!!.

if you have your bov spring too loose it doeasnt vent properly so the air is forced back through your turbo (the wrong way ) to the

doooo dooo do do dod do do noise you hear is the blades of your turbo cutting through the air .

as for bov increasing power im no expert but if that were true it would be stated in the sticky about skyline power mods .

Awh nu someones sarcasm detector is busted, PS air doesnt go backwards through turbos, the sound you hear is what heppens when the turbo is pumping more air than the engine can swallow so yes the air stops flowing but it doesnt go backwards.

And if it is not opening at low boost you know it isnt opening at idle wich should avoid a lot of the stalling problems if you run it to atmosphere.

why not.... when people put atmo bov's on their street cars just for noise/wank factor they draw attention from the police which in turn makes all of our lives harder.

Id agree with that.

Personally i think the stock BOV sounds like a sack of crap with a pod filter. But thats just me. I stuck to the stock airbox for a while because of it. But even with the stock airbox, it still sounds pretty horrible.

I came accross a brand new Genuine GReddy RS for a ridiculous price. Thats the only reason i bought it. Im quite fond of the sound and managed to tune the richness more or less out of it. Flutters a bit with low rpm, but nothing to worry about.

BOV's are not the reason cops target these kind of cars, And is buying a nice sounding exhaust a "wank factor?" no, theres nothing wrong with making your car sound the way you want.

Some BOV's sound like absolute crap and some are really nice, hense the reason for these kind of threads.

and if its illegal in your area then don't get one. simple

Hard. ive just gone back to the factory airbox after having an HKS pod, sounds 100% better and has more response.

Factory r33 series 2 and r34 turbos sound like poo through a pod.

Id agree with that.

Thats a very similar reason to why I changed mine, I dont like the sound of the stock one and I got a Greddy Type RS (Copy but, not genuine) for really cheap brand new. Mine is plumbed back, Sounds a bit like a SSQV but a bit more original.

I get peoples points but, theres alot of people that go buy blow off valves thinking they will get power gains and look heaps sick but end up with a stalling car that chews fuel.

No, they are not THE reason.... but they don't help... and they are not required for most applications like an exhaust is....

for a car to make, lets say 300rwkw (as that's the new 200rwkw) you NEED an exhaust, however the stock bov is totally fine in 99% of applications

i am running the stock bov with an HKS 2835 and it has seen 20psi all day every day for over 2 years now, and has been on a couple of excursions to 30psi when a vac line popped... never missed a beat

also... why do you think the cops always look for a bov when they pull you over? its because they hear atmo bov's from across entire city blocks and it attracts their attention... the wrong kind of attention... for no reason other than sounding fully sick

Yeh i understand where your coming from. so that covers the performance side of things, but the OP wanted to know the best sounding BOV also.

TBH im just sick of people knocking blow off valves, getting a nice sounding one does NOT make you a poser or a wanker or whatever.

I just want my car to sound nice and the way i want it.

And im in NZ so cops dont give 2 sh*ts about blow off valves. and ive never been pulled over for the sake of having the car i do

If you have aftermarket turbo, block off your blow off and get the flutter going. Everyone on here pretends that they hate it when really in my opinion, its the best sound. Just 'cos someone wants flutter doeskin give you a free ticket to bag and abuse a member.

wait guys are bovs illigal even if you get them plumbed back????????

my gtt is fitted with a ssqv along the cooler piping blowing in the atmo, so i just bought a plumb back nipple to connect a hose from it back to wer the stock bov plumb back pipe is.

sooo wat im doing now will make the bov leagal and no chance of defect on the bov???

    • The values for HID colour are also defined ~ see https://www.legislation.gov.au/F2006L02732/latest/text  ~ goto section 3.9 onwards ....
    • So, if the headlights' cutoff behaviour (angles, heights, etc) are not as per 6.2.6.1.1 without automatic levelling, then you have to have to have automatic** levelling. Also, if the headlight does not have the required markings, then neither automatic nor manual adjusters are going to be acceptable. That's because the base headlight itself does not meet the minimum requirement (which is the marking). ** with the option of manual levelling, if the headlight otherwise meets the same requirements as for the automatic case AND can be set to the "base" alignment at the headlight itself. So that's an additional requirement for the manual case. So, provided that the marking is on the headlight and there is a local manual adjustment back to "base" on the headlight, then yes, you could argue that they are code compliant. But if you are missing any single one of these things, then they are not. And unlike certain other standards that I work with, there does not seem to be scope to prepare a "fitness for purpose" report. Well, I guess there actually is. You might engage an automotive engineer to write a report stating that the lights meet the performance requirements of the standard even if they are missing, for example, the markings.  
    • Vertical orientation   6.2.6.1.1. The initial downward inclination of the cut off of the dipped-beam to be set in the unladen vehicle state with one person in the driver's seat shall be specified within an accuracy of 0.1 per cent by the manufacturer and indicated in a clearly legible and indelible manner on each vehicle close to either headlamp or the manufacturer's plate by the symbol shown in Annex 7.   The value of this indicated downward inclination shall be defined in accordance with paragraph 6.2.6.1.2.   6.2.6.1.2. Depending on the mounting height in metres (h) of the lower edge of the apparent surface in the direction of the reference axis of the dipped beam headlamp, measured on the unladen vehicles, the vertical inclination of the cut off of the dipped- beam shall, under all the static conditions of Annex 5, remain between the following limits and the initial aiming shall have the following values:   h < 0.8   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   0.8 < h < 1.0   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   Or, at the discretion of the manufacturer,   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The application for the vehicle type approval shall, in this case, contain information as to which of the two alternatives is to be used.   h > 1.0   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The above limits and the initial aiming values are summarized in the diagram below.   For category N3G (off-road) vehicles where the headlamps exceed a height of 1,200 mm, the limits for the vertical inclination of the cut-off shall be between: -1.5 per cent and -3.5 per cent.   The initial aim shall be set between: -2 per cent and -2.5 per cent.
