aerialbender262 Posted August 11, 2013 Share Posted August 11, 2013 Hi guys...I'm not used to forums so please be patient... Now then...I gotta 350z-gt4 2005 36k on the clock. From day 1 of having this car it has a beautiful high pitch whine when accelerating away (sounds like a supercharger) Now some tell me this is not a characteristic of the car and it has a fault??? Can anyone shed light on this PLEASE...? Quote Link to comment Share on other sites More sharing options...
Fluke Posted August 11, 2013 Share Posted August 11, 2013 (edited) Do you happen to have your girlfriend or wife in the car with you when you accelerate and does it stop when you slow down? Edited August 11, 2013 by Fluke 3 Quote Link to comment Share on other sites More sharing options...
KyleR Posted August 11, 2013 Share Posted August 11, 2013 What happens when you let off the accelerator? Does the whine die off with the revs or does it just stop flat? Quote Link to comment Share on other sites More sharing options...
aerialbender262 Posted August 11, 2013 Author Share Posted August 11, 2013 Gotta think now...? Pretty sure the whine is there while its accelerating only...only noticeable in 1-2-3 gears (from memory) not driven it for 3/4 days... Should have mentioned before in case this makes any difference? the car has Scorpion back pipes on...As said its a lovely supercharged sound, you notice it as soon as you pull off at low speeds...

Ekona Posted August 11, 2013 Share Posted August 11, 2013 Gearbox whine, I reckon. Fairly normal, seems to be more obvious on the HR cars though. Quote Link to comment Share on other sites More sharing options...
Ricey Posted August 11, 2013 Share Posted August 11, 2013 Having owned a supercharged car that would not be a sound I'd be happy about if its really that distinctive and loud. Little gearbox whine is fair enough but supercharger sound .......eek Quote Link to comment Share on other sites More sharing options...
aerialbender262 Posted August 11, 2013 Author Share Posted August 11, 2013 So should i be worried about this??? call me stoopid but what are HR cars??? Quote Link to comment Share on other sites More sharing options...
Ekona Posted August 11, 2013 Share Posted August 11, 2013 Ones with the HR engine, the 313 ps/309bhp cars. Quote Link to comment Share on other sites More sharing options...
Ricey Posted August 11, 2013 Share Posted August 11, 2013 Depends how loud it is. Get it into a garage that you trust for an opinion or see if you have a local forum member knocking around local who can have a listen to if for you and give an opinion.

Omegamanuk Posted December 30, 2013 Share Posted December 30, 2013 I've just recently purchased a HR and would mines the same when giving it some hammer, I came to conclusion it's a characteristic.

BulletMagnet Posted December 30, 2013 Share Posted December 30, 2013 If it is the gearbox, try to find out when gearbox fluids were last changed Quote Link to comment Share on other sites More sharing options...
Desey Posted December 31, 2013 Share Posted December 31, 2013 I make a high pitched whineing noise whenever I fill up with gas 1 Quote Link to comment Share on other sites More sharing options...
GIXXERUK Posted December 31, 2013 Share Posted December 31, 2013 If you rev the car when stationary does it make the sound ? Quote Link to comment Share on other sites More sharing options...
aerialbender262 Posted January 3, 2014 Author Share Posted January 3, 2014 If you rev the car when stationary does it make the sound ? ...Nope not at all, the whine is a lovely overtone to the engine note (noticeable between 1-3-4 after then its all scorpion pipes and road noise???? the whine isnt that loud really, your just aware of it there. I dont think its a fault just a characteristic (but as said i'm a wheels man no mechanic!) Quote Link to comment Share on other sites More sharing options...
