Should be fine. When measured at 30m in the open I'd be VERY surprised if it fails.

Also, the measuring gear is at the front gate and we are at the back of the property (so 300-350m away).

I wouldn't be.

Road noise tests are done at partial throttle holding a constant RPM. Full throttle = f**k loads louder.

When some cars back off they can spike 10 - 15 DBA...

The test of 95DBA at 30Metres that CAMS uses, is at full noise while the car is being driven on the circuit, and can be take at any point on the track, including when the car backfires.

It will be the same at Sutton, the vehicle must ALWAYS be under 95DBA from 30 metres away via EPA stipulation. Not just when it is being slightly free revved in the car park.

Some valid points there Matt but really it's a nonissue. Thanks though.

CAMS are not involved here, and Sutton has outlined to me their guidelines on noise which are the same as when I ran this event years ago.

If you'd like to continue, PM me, otherwise please don't post like that as it makes the noise issue sound like a big issue which will deter entrants who haven't been to this sort of thing before when realistically it won't be a drama.

Edit: It should also be said that previously SAUNSW has run at this venue more than once and not had any issues with noise - even allowing straight pipes for exhausts and externally vented wastegates doing burnouts on the skidpan. One time there was a complaint from the old bloke down the valley who has nothing better to do but the Australian Rally Championship cars running around with their anti lag/launch control was the reason for that. Inspectors came, I explained the ARC cars are loud, they watched for about 15 minutes then left and didn't care.

so if i have an external gate and pass the noise test is there an issue???

As Dave said, as long as the exhaust gasses all go through the exhaust and not out a screamer that's the main thing

I wasn't making an issue of this, I was clearly pointing out that people need to be aware of how road noise tests are conducted are VERY different to EPA (At Events like this) and Race Track noise levels. Maybe we should stop educating people because facts might scare them... What do you think?

As you had noted, the DBA meter is a fair distance from the gate, so it should be a non issue.

Hey Stevo,

Keen to help out, whats involved? Do we just rock up as spectators and go from there? It'll be my first event as a member of NSW SAU :woot: but 99% sure it'll just be as a spectator...

Will be good to put faces to a few names regularly seen on SAU!!

Yeah basically just show up about 830am and say Hi, after drivers briefing I'll call the officials to stand to one side to make sure we have enough to start the day, then you choose a corner you like the view from (if you like to take pictures, thats cool bring the camera) and we set you up with a seat, some shade, few drinks and food etc plus a radio. In front of your spot will be a chicane made up of orange cones which cars have to drive through (just like the ones on the video). If someone doesnt drive through it at all, or knocks a cone down just say on the radio "car number XX hit 2 cones" or "car number XX totally missed gate" and we apply a time penalty to that cars overall course time. If a cone is knocked down, it's great if you can stand it back up before the next car comes through to save a course car having to do it (as it takes the course car longer because it has to come from the start whereas you're sitting right there). Only one car on the course at a time so just as I will say it to the officials on the day i'll say it now, dont be afraid of picking up the cone if one gets knocked down, if you radio in "cone knocked down" you can also say "and im picking it up" - we wont let the next car go until we hear "cone fixed" or something similar to let us know you're off the track.

As many cold drinks and hot food as you'd like will be brought out at regular intervals, also if any officials want to swap corners thats easily done too (for example, you can do corner 1 first, then corner 4, then corner 7 or whatever one you like the view from) - I wouldnt expect someone to sit in the same spot all day (of course if you prefer that, thats perfectly cool), so I'd expect the officials do say 2 hours at one corner, then 2 at another etc.

It doesnt matter even if you only want to do it for the morning and not the afternoon, all help is appreciated and it's so simple to do - plus you get WAY better viewing than any normal spectator will ever get at this place

      What brakes on R34 GTT(Europe)

      By Duncan · Posted

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      Duncan's V37.......race car?

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Duncan's V37.......race car?

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
