Is this type of "open" air filter illegal too? I had a cop look at it once and say "I don't think that air cleaner is legal". It is a genuine Ford air cleaner, lol.

Ummm, I would have thought that with them junking the engines after each race it was probably weight and plumbing that was not needed, but I will leave you to have your opinion.

like wally said
Atmos BOVs the noisy ones are rice on most cars and vent the metered air charge into the atmosphere. which the factory computer thinks is still being fed to the engine.
plumb back BOV's like factory recirculation valves return the intake charge back into the intake before the turbo keeping the precisely metered air charge correct.

simple answer = yes it is ‘illegal‘. That’s not the original cleaner assembly so while its a nice shiny engine bay, I wouldn't be writing a RWC for it. It needs to be remembered that the air cleaner assembly is also engineered as a silencer to suppress induction noise and the car must meet certain ADR's pertaining to drive by noise levels. An open or pod filter has little silencing effect so would render the car un-roadworthy and or the mods could be deemed illegal if they interfere with the engines original emission control systems. Don’t ask your local coper, 99% of them don’t actually know the rules (nor do they need to) if they have doubt they will issue the cannery and than its up to you to prove that its legal...... nice car BTW

Both are illegal due to emissions standards.

I do disagree however with an unboxed airfilter or pod filter being a waste of time. I have experimented many times myself on many cars and read a lot of articles and I do not support the opinion the it is unbeneficial. It depends on the particular vehicle and set-up, so many variables ect. often the negative impact of more heat is more than offset by the positive of more air and vice versa - you have to tinker...

I agree in part merlin, performance improvements can be had if the factory system is a poor design but IMO, most standard engines won't benefit from the change, but added to improvements in exhaust, carburetion and or ECU mods than a modified CAI can really start to make a difference. Unfortunately many people associate the increased induction noise with improved performance, or just think it makes their otherwise standard car sound tough........... :

Agree with the 99% of the police don't have a clue but guilty until proven innocent? Isn't it supposed to be the other way around? You can also recieve fines, demerit points and be sent to the EPA on a hunch of someone in uniform who doesn't know what a turbo is let alone if a vehicle has one.

The things that skew the argument about pods and pipes is the remarkable results enthuisiast maintain they garner. Generally the gains are at the expense of something else or made on an engine with a standard ECU which has been tuned for longivity.

A pod filter should be of no consequence to breathing ability, but the standard filter box may need it's intake mouthed more.

A CAI system will have an effect, mainly due to pipe length changes. With a standard ECU you can usually predict the change to be:

Short pipe (ram pod) :- higher bottom end power, lower topend power
Long pipe:- lower bottom end power, higher topend power

Somewhere in between will invariably give the best result...... usually resulting in the filter being inside the engine bay, not in front of the grille as implied by CAI

Thanks

The only thing lame about the R33 is the way this one was modified.

Even if they came from the factory with a vacuum operated hot/cold air flap, like the XC/D/E??
Can you back this up with a link? Something I can print out and put in my glovebox for the next time Sgt. Schmutter pulls me over?

[paulie0735]

Bottom line is very simple, the vehicle is designed to comply with ARD's these design rules are protected by law! If a cop, or any other authorised agent of the gov suspects that the car has been modified in a way that contravenes the law than the responsibility rests with you to prove it isn't! The truth here is that there is simply no room for modification to any part of the car that is controlled by ADR's. No different to any other law that is put into place to protect the population at large. For example, you aren’t allowed to change the plumbing in your house so that the sewage empties into the storm water system and there are a million more examples where we are controlled by laws to protect the population. Emission controls are put into place to help keep our air breathable. If you don’t want the hassles than don’t mess with ya car, just don’t complain if you choose to modify your car illegally and than get caught. I'm no saint, but I do understand that if you do the crime......

[GXL078]

Pitty they don't make them tune all the smokey trucks.

[Dauphin]

Hmm, interesting. One of my friends has a Nissan 240 and in the engine bay it has this massive flying-saucer pod-like filter exposed. I might let him know it's an issue.

He'll probably just laugh at me though.

the mid 80's represent the peak in emission controls designed to try and clean up dirty engines. This era saw the introduction of EFI and ECU's designed to help the engines to meet the ARD's of the day. I have no idea where you’re getting your info from ebfalcon13.5.............

[NC_Steve]

IMPCO 300A gas mixers use an exposed air filter. How could this part be fitted legally to vehicles if exposed air filter elements are illegal?

They could save money by tuning the diesel engines correctly. Black smoke is often due to too much fuel and can put more soot into the oil.

If it's really a crime then innocent until proven guilty applys. What about the mechanics that install it all? There's a hefty fine if a workshop installs an exhaust without a CAT but no-one asks where you got an aftermarket ECU installed.

R33 is a JDM only vehicle and as such was never designed with ADRs in mind : ADRs are also only applicable to a point such as pre 86 vehicles can have a slightly louder exhaust.

Besides one if the rules are no modifications to the standard ECU which is also a common modification to police vehicles :togo:

That's what I meant. Notice how the big dollar fuel tankers blow no smoke. The flap atthe top of the stack just sits open, no smoke

[paulie0735]

Your right fairmont99, apart form a few exceptions like the one you mention with the cats, the law doesn't care what you (or anybody else) does to your car, its only a problem when you drive it out on the public streets.

Quoting an instance where people (mates) have gotten away with this or that is hardly stating the law!

The Grey import is a weak argument in this thread as it’s imported under a loophole in the law in the first place so what you can get away with in them is not a safe assessment of what you can get away with generally. A loop hole that is closing very quickly I might add and not before time IMO.

Why? It is a nice looking car, very reliable and quick, he likes the noise of the bov, why is that "lame"? pffft :

The poor bloke went to the shops, jumped back into the car when he was done and the copper heard the blow off valve, he wasn't fined for reckless driving or riot and affray, mate. It was an ******** cop who was probably having a bad day and thought he would save the world by fining a guy whos car was too loud for his liking.

Lol?? I was just asking if it was right as I was not aware that it was illegal, gee what is with the attitude with some of you blokes? FFS.

[INDEEP]

Ford_Crazy, if you only take on one piece of advice from the users of this forum; please let it be mine. Have your cousin get onto Vic Roads (or whoever the governing body is in his state), and get the vehicle standards emailed/posted to him. Eliminates all confusion straight off the bat.

Let's face it, if 90% of forum users knew as much as they think they did, they probably wouldn't be on them in the first place... I signed up because I needed to find out something (not related to rego or vehicle standards however), and I'm sure many other users did as well...


Cheers,

Rus.

[paulie0735]

I'm struggling to understand what the confusion is re all this. It’s very, very simple. All vehicles have been engineered to comply with the Australian Design Rules applicable in the year/month it was manufactured. If you choose to modify any part of your vehicle that was engineered to comply with these rules than the onus is on you to prove that your vehicle still complies with the rules. Could it be any simpler than that?

Here’s a link to the ADR’s ……enjoy!
