If the engine has:

i)i) 5 cylinders or less 4000 rpm.

ii)ii) 6 cylinders 3200 rpm.

iii)iii) 8 cylinders 3300 rpm.

iv)iv) more than 8 cylinders 4300 rpm.

v)v) If the engine is a rotary engine 4500 rpm rpm.

In selecting the 45 degree alignment from the outlet of a motor vehicle fitted with two or more outlets, only the angle resulting in the microphone being farthest from any other outlet must be used.

4.1.44.1.4 The height of the microphone above the test site surface shall be equal to that of the orifice of the exhaust outlet ±25mm but shall not be less than 200mm above the test site surface.

4.1.54.1.5 The distance of the microphone from the exhaust outlet orifice shall be 525mm ±25mm.

having an exhaust silencer is illegal in nsw

Yeah its illegal but honestly wouldnt you rather put it on ? I was with my cousin on the weekend he has one on his RX7 And his got a bridgeport 13B Very Very loud , A police officer pulled him over and asked him why it was so loud ( He didnt see the police officer in enough time to press the button ) He told the officer there was a loose screw in the engine thats why it was loud he opened up the bonnet made it look like he was screing something pressed the button and it went qiuet and the cop believed him :thumbsup:

ahh no, i got my exhaust done by hi tech mufflers made to pass db levels (84db at 4800rpm) so i dont have to dick around with silencers and have to put up with that annoying drone in the cabin. and it's not restrictive at all. i honestly don't know how people drive around with loud exhausts day in day out.

and it's sounds like that cop was a dumb shit btw :thumbsup:

Do cops know if you have a silencer or not?

you would get into alot of Sh*ts if they found out rite? :P

is it possible if u could record ur exhaust with and without the silencer? :thumbsup:

another question... r motorbikes, truck & buses the same? i.e 90db? or do they have another figure?

I read somewhere that cars were to be 90db or less and motorbikes 93db!!!!!

Harleys are that at least just at idle!!!!

I've been sent a letter home from the EPA surprisingly for a reported loud exhaust, mine is pretty darn quiet. Someone must of dobbed me in.

Anyways had to go to a muffler shop and get it tested.

For a Skyline, the letter said it had to be revved to half the rev range, but mine said 4500rpm. Got it tested, all was under until the throttle was lifted at which point a couple of small pops set the reader over 90db.

Ouch!!! Get a life dobbers!!!

sorry man i dont really have time for the track ,

Look cops can bust you for a silencer but what can they do ??? They can issue you with a defect in which case you wil go pass it and then go from There ??? But i dont think many cops would pick these electronic ones as it is very hard to notice it unless your the smartest cop around. there aint many of them :thumbsup:

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
