I managed to pass the noise testing, but it took a lot of sound proofing and induction pipe trials before I got even close.

The brake testing is pretty freaky at 160 Kph - I am glad it was the engineer doing this and not me! The tyres and brakes sure get a workout.

Ben,

I really hope the RTA are reading this.

I passed the noise test with my car by doing exactly what Ben did and wrap everying up seal off all holes like side vents well wells etc.

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.

I should have been clearer guys, no issue talking about the stupidity of 160 Kph brake tests in an open forum - it probably deserves it's own thread.

I do think that we need to be careful about discussions on passing noise, officially our cars should stay in the same configuration as when complied.

Cheers,

Ben

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.

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.
