DJsickboy Posted January 7, 2009 Posted January 7, 2009 So this is weird... My Z is behaving strangely.. The revs seems to rocket up but without much drive... It does it in first second and third. I also get this funny twitching feeling from the back end accelerating out of corners!!! It definately seems to be much slower through the gears because of these problems.. Seriously though I do have a strange problem, first thing in the morning for the first mile or two I have a strange whisltilng noise like I have left the window slightly open or one of the tyres is very fractionally rubbing on something, It is a speed thing in as much as I have dipped the clutch and its still there, dab the brakes.. same, check windows (obviously) still there. As soon as it gets warm it dissapears and doesnt come back till the next morning even after being left alone for 9 hrs during work..?? Other than that its been 3 months now and 6000 miles later and I still love it. I also seem to have a permanent stupid grin plastered over my face most of the time, this is occasionally replaced with a look of horror once in a while but not enough to worry me too much. I find the traction control a bit unpredictable, sometimes its like a car with turretts, other times it seems quite laid back about it all and lets it slide quite a way before I get the slap on the wrist. Bit dodgy pulling out of junctions...... go go stop go go stop. But I have to say that I am enjoying this weather but I dont think the Nismo rims are, or the paintwork... Onwards upwards and forever sidewards Jay Quote
IanS16 Posted January 7, 2009 Posted January 7, 2009 I get the whistling noise too! Wasn't going to post as I thought it was me going mad! No idea what it is though. Quote
M13KYF Posted January 7, 2009 Posted January 7, 2009 your exhaust may be going. Where the pipe joins the rear box, it splits. Can sound a bit like a supercharger whine. Revs may be the clutch slipping Quote
H5 Posted January 8, 2009 Posted January 8, 2009 your exhaust may be going. Where the pipe joins the rear box, it splits. Can sound a bit like a supercharger whine. Revs may be the clutch slipping +1 How many miles has the clutch done? Quote

What shoes is she riding on? If they're a bit tired/worn or rough. Presuming of course that you're not on stock tyres too? Quote
DJsickboy Posted January 8, 2009 Author Posted January 8, 2009 Thanks for the replies... The revs going up was me being scarcastic/daft sorry , its because of the cold weather and slippy roads it just spins everywhere.. something I am sure we are all experiencing.. Its only done 5k total mileage so I think the clutch is good.. hence the back end twitches.. The whiney noise is a strange one, I dont think its the exhaust as the car is only 3 months old, its defo a wierd one, sounds a bit like an air leak getting in somewhere until it gets warm and then goes away... The tyres are Falkens on the 19 inch Nismo rims with very good tread with pressures at 35psi... Do these rims + tyres affect the TCS because the are bigger? It is very unpredictable, sometimes it chimes in too early sometimes a bit late.. Its no big deal but a tad confusing/fustrating especially at junctions or exiting roundabouts. In warmer days I just switch it off cus I prefer it that way but in this temp with the black ice and dodgy roads it stays on!! Jay Quote
IanS16 Posted January 8, 2009 Posted January 8, 2009 I agree, it really doesnt sound like the exhaust. Its more like the window rubbers have frozen and are not forming a seal or something. (are we talking about the same thing?) Quote
DJsickboy Posted January 8, 2009 Author Posted January 8, 2009 Yes mate I think we are!! I didnt want to ask either because I thought I was going nuts but it is definately there.. Maybe thats it... You may have hit it on the head, maybe the rubbers are compressed by the window and when its very cold the stay in that position untill some warmth expands them to close the gap??? Dont know meself but I have tried my hardest to at least pin it down to an area with no joy.. Quote
pturbo Posted January 8, 2009 Posted January 8, 2009 i have the same whistling noise lads,i keep thinking the window isnt done up fully,but i press the button and it is.lol Quote
DJsickboy Posted January 8, 2009 Author Posted January 8, 2009 what size tyres have you got on 245/35/19 fronts and 275/35/19 rears... To all who have experienced this phenonmenonon.... Mine gets louder/higher pitched or quieter/lower pitched depending on speed... yours the same? Jay Quote
xStric9x Posted January 8, 2009 Posted January 8, 2009 I get the whistling noise too! Wasn't going to post as I thought it was me going mad! No idea what it is though. I get the whistle aswell but only between 3-4k revs and then it disappears. Defo not the zorst as mine is new. Quote
zedwagon Posted January 8, 2009 Posted January 8, 2009 been meaning to post this for a while as I get the whistling noise aswell ! only happens in winter when temp is less than about 5 degrees and sounds like wind whistling through a window (it warbles a bit aswell) but not really in time with acceleration, more the car's movements and going over bumps etc, it then stops after a couple of minutes could it be coming from a belt? Quote
T2 Posted January 8, 2009 Posted January 8, 2009 Don't get any noise any more, turned out my driver door switch was not working as it should and my window was not being fully closed even though it looked as if it was Quote
martinmac Posted January 8, 2009 Posted January 8, 2009 See what happens when you buy cars with metal roofs Quote
xStric9x Posted January 17, 2009 Posted January 17, 2009 Did anybody ever find out what the whistling noise was? Quote
Stew Posted January 17, 2009 Posted January 17, 2009 I treat all my rubbers with Gummi Pflege. I got no whistling. It's worth a try! ebay clicky Quote
Tilly Posted January 17, 2009 Posted January 17, 2009 Looks like a few of us are 'whistling' to work on a morning My car also does this, just for a few mins until it warms up. My whistle seems to come more from the front of the car, I put it down to air flow thru the 'grill' on the front bumper, but would be interested if anyone really does know what it is. Who needs the radio on what with the whistle combined with the nismo exhaust who needs music baby Quote
xStric9x Posted January 17, 2009 Posted January 17, 2009 I treat all my rubbers with Gummi Pflege. I got no whistling. It's worth a try! ebay clicky Its definately coming from the engine Stew and as said it only happens between 3500-4000rpm. Quote
Chris s Posted April 15, 2009 Posted April 15, 2009 Gents - did anyone find a cause or cure of to this wind noise / whining / whistling? Is it the rubber seals which need some treatment or is there some mis aligned piece of body work or a window which needs resetting? The noise in my car does seem to be coming from the passenger side slightly behind the seat... but the sound is audible even with the windows open so do not think it's the actual alignment of the glass. Am loving my Z so want to enjoy it even more without this noise! Quote
fatalus Posted April 15, 2009 Posted April 15, 2009 I have exactly the same noise for a couple of minutes. Only when cold outside and over 40-60 km/h. Ordered Gummi Pflege to try. At least it is hot these days and dont hear a thing! Quote
Chris s Posted April 15, 2009 Posted April 15, 2009 I have ordered some of hat too...will hopefully see some improvement when I apply it... I did hear the noise again this morning but it was colder than the weekend so it could well be temperature linked, will keep you posted Quote
Chris s Posted April 26, 2009 Posted April 26, 2009 I bought some Gummi Pflege from e-bay and have applied it liberally to every rubber seal I could find to hopefully stop the whistling .... but no luck! The noise seems to totally unrelated to the windows as it whistles even when they are down. I have not pin pointed where it comes from but it does seem come from the rear and only appears when I'm doing 45mph and above, I have checked for any signs of damage, lose trim or misaligned body parts but it all looks as it should. Has anyone else had this issue .. .and ideally fixed it? Quote
