Nyezhov Posted December 4, 2019 Share Posted December 4, 2019 It makes me nuts because I dont understand it. Im an early riser and my palace of love is near the main street route to the port area. Plus I have a traffic light. So at 5am, when the gaily painted heavy trucks are taking off from the light its like weeeeeeeeeeeeeaaaaaaaaaaaawww as they run through the gears. My bud says its the turbo on the little engines they use but it doesnt sound like a turbo whine, it sounds like a tranny whine, or even a whine coming from the pumpkin. It sounds horrible and its not like its only once in a while, its from all the trucks. My question is, why do they whine so loudly. Is is a mod for torque or something? Any motorheads know?

Docmartin Posted December 4, 2019 Share Posted December 4, 2019 Is the pumpkin being pulled by mice ? If so you've got a Cinderella problem. The noise is probably turbos spooling up and then maybe wastegates opening. Link to comment Share on other sites More sharing options...

metisdead Posted December 4, 2019 Share Posted December 4, 2019 To avoid further confusion, topic title has been corrected to transmission so that others are not confused about whining by transvestites. Link to comment Share on other sites More sharing options...
CGW Posted December 4, 2019 Share Posted December 4, 2019 There are a few trucks same up here in the sticks, pretty sure it is some sort of "device" that is supposed to sound like "turbo" it's not, pathetic kids playing with their toys? Link to comment Share on other sites More sharing options...

I was wondering if its some kind of "noisemaker" because to me, If I was driving something and heard a noise like that Id pull over and stop driving. Especially coming out of a manual box on upshift.

Coremouse Posted December 4, 2019 Share Posted December 4, 2019 Also curious, my AWD Celica also have pronouced tranny whining, thought it is cute, but puzzled where it came from? Definitely not wheel bearing had all new on 4 wheels. Is it axle? Viscous coupling? LSD? Or just worn gears? Btw. this video car had a similar whine to mine( note 02:40 the car come to a stop ) : Link to comment Share on other sites More sharing options...

DeeMoney Posted December 4, 2019 Share Posted December 4, 2019 If they are diesel pickup trucks then it is the sound of the turbos spooling up. On newer trucks the sound is muted and can only be heard if the engine is being revved high. However, they can be modified to have bigger turbos and sound deadening within the engine compartment removed to increase the noise. Link to comment Share on other sites More sharing options...
Nyezhov Posted December 4, 2019 Author Share Posted December 4, 2019 Yep. Sounds like a deep and loud turbo whistle. What for? Link to comment Share on other sites More sharing options...

Or you can put on an electronic gizmo to make it sound like you have a huge turbo! along with a couple of hundred rear view mirrors, some spotlights, a Michelin man or two, a very load noisy exhaust mod and some coloured wheel nut covers and you will be the envy of all - least if you are very small minded & think like a "man child" you will think so!

That's description is it !!!! although I never look askance at anyone's choice of customization, since I started with a baseball card clothespinned to the spokes of my Stingray bike!

dddave Posted December 4, 2019 Share Posted December 4, 2019 The yellow air-con buses have a similar whine..very distinctive and it does cut through the normal roadway din, especially at night. Luckily, most of the AC buses stop running after midnight. Link to comment Share on other sites More sharing options...
LennyW Posted December 4, 2019 Share Posted December 4, 2019 It is indeed turbo whine, often coupled with outrageous modified exhausts, they are damned annoying. Link to comment Share on other sites More sharing options...

NanLaew Posted December 4, 2019 Share Posted December 4, 2019 Compressor surge or turbo flutter caused by back pressure. Truckies here mess with the stock waste gate on their diesel engines to get that cool (to them) sound. Link to comment Share on other sites More sharing options...
Jitar Posted December 4, 2019 Share Posted December 4, 2019 Most diesels don't have wastegates. A lot of the older trucks have more open exhausts making turbo whistle more obvious when working. Trucks do make a bit more gear whine than light vehicles due to more drive-train components (range change, power dividers between axles etc) and higher loads. Gear whine is lower frequency that the turbo whistle. Link to comment Share on other sites More sharing options...

So that loud, falling "Owwww..." as the driver takes the foot of the accelerator and up-shifts is coming through the modified exhaust systems? I've never heard the older 'long nosed' Isuzu's ever making that noise but just about every second newer cab-over one does. Link to comment Share on other sites More sharing options...
