1. usually over 10% of the speed limit, ie over 88 in 80 zone

2. not really sure on this but i think someone mentioned 6-8 weeks or something..

I've heard of many cases where they've been set to less than 10%.

DO NOT speed past them.......

From big-ass trips... speedos are usually set to be lower than the speed you're doing.... If you use a nav. unit, it always displays that you're travelling slower than what the speed ostates (they might not take into consideration contours however)... But the speedo-checks on highway to melbourne registered same speed as GPS; which was at least 7km/h under what the speedo read. - so don't get paranoid, but don't exceed the limit. Driving instructors recommend 3km under speed limit to do driving tests :blink:

I thought fines always come within 2 weeks?

Keep in mind that if is IS 10%, it's still not going to be a good measure, due to inaccuracies in your speedo, the camera etc. Just do the speed limit through the camera.

thats when a pfc commander comes in handy :blink:

If you know where they are why would you speed past them?

like a few people have said, speedos in cars generally read about 5km/h over what you are doing. so if the speedo says 100 youre doing 95. so if you go through a speed camera on, or even slightly above the limit, you should be right.

cops with radar/lidar ive heard need to give a 10% leeway. add into account that your speedo is high as well..

many times ive been in a 100 zone, with the speedo reading 110 to 115, and a cop has been there, and i havnt been done.

10% are you kidding me? lol. It's more like 2 or 3km/h. so 63 in a 60 zone will most likely see you booked, as will 103 in a 100 zone. I have no idea who came up with this 10% theory, but it's bullshit.

your theory is no better

it's definiately not 2-3km/h

Too lazy to edit but:

afraid to say.. not a good year for me :)

Just curious to know, do policemen have a Flash on their Radars?? or any other speed recording device (Laser)? etc

I was doing abt 111kmh in a 100 zone :D:( silly me,

I think i saw a flash from behind some trees and an un marked commodore parked some 2km down on the M4

can't be sure if it was me, as there were a few other cars around me doing the same speed...

but then again, i can't even be sure if it was a police flash or some blue light i saw through the trees in a factory or sumthing else :D ..........

dam , sooooo anxious. hope i dont get anything in the mail.

Most radar's do not have a flash, if the radar operator sees someone doing high speeds they would radio the chasing car (in this case I assume it would be the unmarked commonwh0re parked 2km down the road) telling them that x person is speeding and to chase em down.

However there are new radar setups where the radar is on the ground and the camera is behind it. They need to have a good lock on ~3secs then takes a photo immediately. Quite easy to notice this.

I think all police officers are being currently trained to operate radars, all HWP's know how to use radar's already.

As for your case, ADR's specifies 10% tolerence for speeds, so maybe you are being paranoid.

from

http://rvcs-prodweb.dot.gov.au/files/ADR%201803.pdf

5.3. The speed indicated shall not be less than the true speed of the vehicle. At the test

speeds specified in paragraph 5.2.5. above, there shall be the following relationship

between the speed displayed (V1 ) and the true speed (V2).

0 ≤ (V1 - V2) ≤ 0.1 V2 + 4 km/h

The equation means as follows:

95 Being Indicated speed 90 being true speed.

0 <= 95 -90 <= 90*0.1 +4

0 <= 5 <= 13

So there for Indicating 95 but going 90 is in the acceptable range. Were are as

110 Being Indicated speed 90 being true speed.

0 <= 110-90 <=90*0.1+4

0 <= 20 <= 13 Which means its not acceptable.

So the allowable difference depends on the speed the car is actually traveling.

Put easier, your indicator must NOT be showing a slower speed then the car is travelling, and it must not indicate more the 10%+4km of the true speed

So In a 60 zone, your indicated speed must be between 60-70 to be ADR approved.

In a 80 zone, 80-92

In a 100 zone, 100-114

In a 110 zone, 110-125

You are wrong as far as NSW goes ( as we speak, plans are in place for much less leway) but you are correct as far as VIC goes, 63 in a 60 zone ,84 in a 80 zone and they get you. This is speed cameras only, its up to the cop if its a none camera speed trap. What gets me in the case of VIC is the fact that the equipment they use to measure speed has a plus or minus 3% accuracy according to manufactures guidelines, if I was booked for doing 63 in a 60 zone I would defend it in court and I would win everytime!!

yeah true. I still don't believe it's anything like 10% though. Someone please drive through a 110 camera at 122 and tell me what happens :P my guess is fine.

      Possible swap on R34 RB20DE NEO?

      By GTSBoy · Posted

      If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Turn signal wiring question

      By GTSBoy · Posted

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
