Torbo whine

[Jim Smith]

I just started to get a turbo whine at start up speeds and then it goes away. I have 12k miles and I wondered if this is normal. All help is appreciated. Thanks.

Nothing like the sound of a trubine! It's normal. Can't get rid of the noise, but you can make it sound louder!

Turbo Sound

The new Fords really have that sound upon startup. Their turbo's are louder.

Oh yeah, the Ferds are LOUD! Some kid around here has an '04 F350 CC long bed 4x4 with a 6. 0 PSD, lifted to the sky with 38's. He didn't say what kind of intake, but he has removed the cat and straight-piped it. Otherwise the truck's stock.



You can literally hear his turbo coming or going from 1/4 mile away or more. It is unbeliveably loud. I don't know how long I could drive it like that. Sounds sweet, though. It must be the VGT turbo. I can't wait to see a Cummins with one.



As far as turbo noise on my truck, I think after a while I just heard it more (with the stock airbox) because I was listening for it.



Last weekend I drove 200 miles with the radio off. I find myself doing this more and more. I was only listening to the symphony coming from under the hood and my exhaust

Does it sound more like a roar, than normal turbo whistle? - Could be your cooling fan kicking-in. Only engages up to 20-30MPH 'ish (when it's warm out and/or your air conditioner is on), then assumes there's enough airflow.
