How to pass the "noise test"???

You are right of course Beejay.... and that's part of the reason photographs are being taken so even your average "side of the road" DOT or RTA inspector can pull them up at his leisure to check for modifications.

Regarding the brake test....I have no objection to the test being done at sane speeds and by some-one who will take the responsibility if some-thing goes wrong.

Regarding noise.....I question a standard which had it's origin in exhaust noise and has now gotten so tight that now we have to address induction noise and mechanical noise. It is getting that way that even a sneaky "passing wind" if heard by these microphones will be illegal.

My concerns are further magnified when certain "interest groups" have favorable attention...ie..Harleys, trikes, trucks,railway etc.. To me....noise is noise.

I can understand brake tests being conducted from the speed limit down, or even 20% above the max speed limit in that state, but from 160km/h? Thats 45% above the max speed limit on roads. Moreso, the roads with the 110km/h limit make up less than 1% of our total roads!

This is ridiculous.

I do not think the noise issue is just us these days - I have a few friends who ride Harleys and they have heard of other riders getting some nasty fines this year.

Cheers,

Ben

20% above NT posted speed limits is 156, Is this 160kph test part of passing ADR (Australian Design Rules)? If so then this could be the direction they have headed?

But I do agree that it does seem mind numbingly stupid to specify a test that requires a vehicle and its driver to break the law.

I do not understand the change to 160kms it makes no sence and as you guys have said I am sure most of the cars will not be driven at that speeds, expecially the LS1 powered cars

I think we have done fairly well with the ICV rule changes in the past, but as Matt has said the move to a more taylored set of rules like the hot rodders would be the only way the ICV will survive.

Good work Baz

Les, the numbers are scary, but this is what could happen.

Phil,

I had a feeling that a certain portion of your post was imminent, and what do you know, there it is. I thought it would make it's appearance earlier, but there you go. I'll have to work harder on honing my psychic powers. See you at the breakfast.

Hi Bobby,
I have been where you are going, I have a G-Force with an LS1. I am in NSW and our DB ratings are very low, so very challenging to get through. 1) restrict throttle to 1/3rd. 2) forget the sidepipes, go one single exhaust, with at least 2 mufflers in-line. 3) get some lead impregnated foam matting and encase the complete engine compartment, under over,sides, everything 4) use an old commodeore air pod, have about 2 metres of hose leading to it and absolutely stuff the pod full of foam, make sure the engine can't suck any foam in. If you do all that you should get through first time. Out of six cars that were being tested on the day mine was the only car that passed!! 2 db under. All the other cars on the day were at least 5db over, some as much as 15db!! Rob...happy to field any questions drop me a line 0411487527

3. The car turns sideways and rolls several times.
4. The engineer survives but is now disabled and unable to work.
5. Workers Compensation knocks back his claim because the accident was on a track and he was driving over the state posted speed limit.
6. Your insurance refuses your claim to repair the car for the same reasons.
7. The last resort for the engineers family is to take legal action against you as the owner of the car.
8. Because the engineer used to earn nett. $k100 per year and had 20 years before retirement they sue you for $2,000,000.00 loss of income, indexed at the court discretion plus $k10 per year disability support and care. Total about $5,000,000.00 minimum plus distress at court discretion.

Obviously you contest and after 5 years the court awards the family $1,000,000.00 and costs. Your legal costs are $250.000 and theirs $300.000.

There goes the farm.

This is ironic. One point first...the owner did the driving and the engineer did the measuring. Now to the irony. The supposed reason for the RTA's high demands was because an engineer passed a hotrod/modified car and the RTA approved it. The owner crashed the vehicle with his pregnant wife aboard and she lost the baby. The owner sued the Engineer so the engineer sued the RTA... sounds like an internet myth but I heard it first hand from a very good signatory engineer.

Thanks for the offer to call you Rob, I will take you up on it.
