Hey guys,

The R33 I just bought has no BOV and as you would expect has your typical no-bov flutter from the air bouncing back and forth. The flutter only occurs when you put a fair bit of load on the engine and it begins to build boost (2800-3000rpm)... Its a GT3582R btw and atm has a pod but am reverting to standard airbox so you cannot always hear it but its still there and would dare say be quieter with the stock airbox.

The big question is, if a cop, 'somehow' were to hear the flutter, could they pull you up and try and get you for an atmo bov (because they probably cannot tell the difference in sounds). If you tried to argue that you do not have one they would probably not believe you etc etc.

Point is, can I technically be defected for this? Has anyone had something like that happen or a similar circumstance. I dont want to have to buy a plumb back BoV just to make it quiet if I dont have too.

Cheers

Its not a loud exaggerated 'dose' like you normally hear its actually really quiet and short with no high pitch lol and doesnt happen if youre just cruising which is good because Im not really into the whole fully hektikkkk dose thing haha.

And yes I am more worried about the huge turbo and will be going to my own measures to make that less sus (probably to no avail).

Could do that angry but its still the whole buying and paying someone to weld it in. It hasnt go any stock piping.

Whack the stock BOV on, pipe it up, then blank it off. Gonna be some effort to fit the stock airbox in with that turbo. I'm gonna assume its got a big intake pipe with a pod on the end. I'd say just make a box out of metal and paint it black. The stock airbox is probably the last concern on any modified skyline drivers mind.

In my old S14, ran no BOV, came out of a round-a-bout one night and shifted gears, cop heard the flutter and pulled me over..

Basically said he heard my BOV, but after explaining it was removed and wasnt running a BOV at all he just left it at that.

Each copper will be different, if they want to defect you, they can and will. Treat them with respect and they may just leave you be.

My 2cents..

No you can't be defected for no BOV. If the cop is a dick he will issue you with a DECC inspection notice and then the inspector will pick out all your defects.

You can. Technically, being part of the inlet tract, it is part of the emissions system and is therefore verboten to alter.

Technically you are correct however a cop won't defect you for a BOV if he cannot see it.

Both times I have had my car DECC inspected I was told by the inspector "Remove your BOV because the people at the EPA don't like seeing them"

That comment alone tells me the pen pushers there are inconsistent in their rulings.

in summary, you can be defected for any modification (removal, addition, change) to the intake / turbocharger system

regardless of what or why

its simply a matter of if the relevant authority notices the modification (removal, addition or change)

Technically you are correct however a cop won't defect you for a BOV if he cannot see it.

I have been defected for an aftermarket ECU, copper couldn't see it.

Basically the police will defect you if the believe its modifies/not original. Then you have to prove it to whoever is clearing the defect.

I'd say nope, not defectable. When my 33 first went over the pits 5 years ago when I didn't know any different, first thing they spotted was my atmo BOV. Got told to block it off, so I replaced it with a blanking plug and they gave the all clear.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
