I am currently contesting a fine issued to my missus whilst she was driving my skyline

They defected the car for being 110db @4500 rpm which is ridiculous

Also by law you only have to rev the car to 3200rpm for a 6 cylinder vehicle which is on the national roads and transport commission website

my car was tested in braddon by roadside police and RTA also at 4000rpm and the car was 91db only a month back

The way they are conducting the tests is false and by law is wrong

I want to borrow a meter so that I can conduct a test properly and take my report to the head of police ACT and also to the RTA themselves as the way the roadside police and Rta are testing is wrong and not correct by law

I have one at work that I MAY be able to borrow. Let me know and i'll see what I can pull, may need to get you to test at my place or something one night after work.

However, just to correct you on some unfortunate facts since I've been through it before as well. The roadside tests (whilst never performed legally to the book) and all metered exhaust tests are to be conducted at 75% of ESMP (Engine Speed at Maximum Power). For an RB25 (I've only looked it up for my engine sorry), the rated RPM to measure it at is 4950rpm including stepping off the gas ubruptly to include that decel pop.

The dickson station has only ever measured at 3200 or 3400 (can't remember the exact one they did for me) and passed without issue, but the roadside, they only ever do 4100rpm+ etc because its the easiest way to get you off the road for driving an import. Which, technically is still legal since by the book it should be rated at 4950rpm.

Still chasing up the doco I had on the ESMP of our engines, sorry.

Ok, found the PDF... http://epanote2.epa.vic.gov.au/EPA/Publica...;FILE/317.1.pdf - 2 and a bit meg in size, give it time to load.

RB20E - ESMP 5600 - 75% reading done at 4200rpm

RB25DE - ESMP 6400 - 75% reading done at 4800rpm

RB26DETT - ESMP 6800 - 75% reading done at 5100rpm

RB25DET - ESMP 6400 - 75% reading done at 4800rpm

Interestingly, cannot find RB20DET listed, which means it should be measured at 3200rpm the way I read it....

Edited by sfrizza

mine has the rb20de engine mine is a GTS not a GTS-T

I also downloaded the Test procedure guidelines in PDF format

which state

vehicles from 1970 to 2000

Default speed tests

Should not be higher than 90db @ the following RPM's

5 cylinders or below test @ 4000rpm

6 cylinders test @ 3200 rpm

8 cylinders test @ 3300 rpm

Above 8 cylinders @ 4300 rpm

and Rotary engines test @ 4500 rpm

That is the guideline set out by the NRTC I can send ya the PDF

Yes, but you are only reading what you want to read there... The guidelines specifically say that it is to be < 90db at 3/4 of ESMP UNLESS they don't know what that value is. In which case they are to do 6 cyls @ 3200rpm as a default setting.

All sorted ...

The Car goes in to the exhaust shop Mitchell for a new cat back section on Wednesday to hopefully Quieten the whole exhaust note a lot so the car isn't such a target

I will also keep my old cat back setup for track days as it is a nice exhaust

Was giving the Varex muffler option serious thought then was told by the RTA that they are infact illegal themselves so a complete catback overhaul should do the trick and shut it up

Want the car to be legal im over getting stupid fines and defects and not being able to enjoy the car for what it is ... I seriously don't have the time for the RTA/Police bullshit anymore

Somehow I keep having a feeling either my name or the cars that I drive are on some sort of police black list

Because twice now when the police have pulled up my missus driving my car they give her a lecture and keep asking her questions about me which I find to be an invasion of privacy ...

They also went right through the car searching everything when they stopped my missus I dunno what they were looking for but they didn't have my permission and I am the owner of the car , she was just the driver ...

Dunno if there is anything I can do about that by law ?

    • 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.
