It might be a leak or hole in vacuum hose. As you increase RPM by pushing the gas pedal, pressure builds in the hoses making a whistling sound (e.g., 65 mph, high idle). High pressure goes down when you release, and the sound goes away. Have someone hold the idle high so you can locate the leak. Also many high flow air intake systems and some stock air intakes make a whistling noise at higher engine speeds. This can be checked by slightly reving the engine while someone listens to the air intake. P.S. Check the breather hose to the PCV valve and the PCV valve itself. Is it stuck? does your engine have a turbo? a turbo working properly , whisltes. if no turbo, you have an air leak, most likely in intake manifold
Your vehicle will go into high rpms and not move very much. Also clutch will start to "slip" as your driving it will just start to rev high.
major vacuum leak?
A defective vacuum line can cause a whistling sound when the vehicle is accelerating. A loose belt can also create a high pitched whistle sound.
lower rpms use less gas higher rpms have more power
yes, a whistle sound is high pitched sound
Boat engines are built to hold high rpms (revolutions per minute) for long periods of time. Vehicle engines are not built for high rps or most of the anyways. Vehicle engines also have more torque the marine engine.
A whistle is a High Pitch because its really loud and not really low.
What cause a whistle song on my gmc jimmy
A seven letter word that means a high shrill sound would be "whistle".
If you do not reach the read zone in your RPM scale, you are fine. Just make sure that you are using a good coolant and thermostat. I would even use low opening temperature thermostat if you like to drive with high RPMs often.
did they want freedom
Probably a worn out engine.
Many time the high pitched whistle will be cause by a loose or unattached vaccuum line on the engine.
Obviously depends on RPMs. Normally 15-20psi at idle. Could be as high as 30-40psi when the engine is under high RPMs.
This is known as the Doppler effect. As the train approaches you, the wavelength of the sound waves it emits are compressed, and therefore the whistle sounds higher. When the train is moving away, the wavelengths are extended, causing the whistle to sound lower. If the train were not moving at all, the pitch you would hear from the whistle would be somewhere between the high and low pitches you hear when the train is moving.
AnswerBombs generally don't whistle (there may be an exception or two). Some mortars whistle or whine. Stuka dive bombers had sirens to terrify the public, although I would have thought a Stuka dive bomber would be enough terror for any purpose.AnswerThe bombs don't whistle, the air passing over them at high velocity does.The whistles are the product of high velocity air current eddies making sound vibrations. Airplanes and whips also make the same types of noises.
Either the throtle cable is hanging or the idle control solonoid is not working
My KIA Sephia is doing the same thing. I was told that my valve body was stuck and needed to be cleaned.
its either the throttle position sensor or the map sensor.
Because your motor is spinning faster at higher speeds causing higher rpm's
