Hey guys,
i need help with some problems...

well here is my Z's problem.
when i go on highway, and passed about 70 mph
start making a " HwinG~" noise !! i thought it was from A/C!!! but i found out today it wasn't from A/C, when i let my gas padel go, it goes away, and press little it start making a " HwinG~" noise again, but passed 70 mph then it goes away again...

anybody has this problem ? or experience on this probm?

 

so it sounds like, '휭~!', lol.
What year is your Z? I drove '03 and it had the same problem as you mentioned but wasn't that annoying.

 

search!!!

Its normal, I dont think anyone know what it really is, but its a good thing.

IMO is some harmonic balance, the engine is at the right amount of work load, getting the perfect amount of air/fuel,etc. -- In short: the sound of healthy Z engine.

Of course this is assuming your talking about, what I think your talking about, its more a hissing sound or what a turbo sounds like spooling up , rather the what ever the hell a HwinG~ noise sounds like

 

haha,
well i got 04, complete stock.

 

I think a lot of us hear the same thing, mine at 80. But it might be a different noise -- I am pretty sure its from the tranny.

 

hopefullly it's normal. =P

 

I think someone has been watching some old Batman Episodes.

 

You should hear what being passed at 160mph sounds like-dont worry about it.

 

=]

 

my eclipse sounds like going any mph haha... **** is beat... i think i might need to get my oil changed for it, but i'm selling it next week so whatevs

 

That sound is a signal that the Turbonator is kicking in. Hold on tight!

 

dont't sweat it bro, enjoy the noises the Z makes

 

haha

 

It's the Tranny. If your cars still under warranty go get it replaced!

 

When I go over 102 mph the air starts whistling past the side mirrors...

 

Its not the tranny, your going to scare the guy. Hearing the tranny whine is common on the Z, buts it unlikely what he is hearing. When its cold outside, often the tranny will sould like a owl howling til the oil warms up, this is normal, especially if your running after market gear oil.

Plus tranny problem shouldnt be assumed til, there is shifting issues.

 

its the turbo spooling

 

if your talking about a whistling, DOHC cars have it (SOHC has it too but it's not as pronounced). under light load you can hear the wind whistle through the throttle body... such a beautiful sound....

 

Spit my lunch out on that one....

 

maybe it's your ring & pinion whining? since the diff is mounted to the body of the car, they are more noticable with that...mine does it too
