no not as in dixon of dock green - anyone noticed how traffic cars have a sort of constant whistle sound when travelling at any sort of speed, any idea how/why? in the bad old days of waiting hours (even days :frowning: ) for an ■■■■■■, you could doze in the sunshine and often still know when they were passing the other side of the motorway to come back for you :sunglasses:

Its the lightbars on the roof, they disturb the air and cause a whistle sound, can be heard on most vehicles with lightbars but the police it is more noticeable as they tend to be doing faster speeds

Turbo whistle??

Flatulence? :wink: :grimacing:

I agree with bug, they have intercooled turbo’s on them, so the whistle you can here is the cooler working.

intercoolers dont make any noise its just another radiator on the front of the engine

at motorway speeds the turbocharger is not actually doing a lot,

and you would not hear a turbo whistle due to the silencer in the exhasut system

trust me its the light bar and maybe even the extra aerials on the roof that is disturbing the airflow across the car :laughing: :laughing:

As Discopete says, the turbo isn’t making any noise at constant speed - listen to your own truck & you’ll hear the faint whistle whilst accelerating but it will tail off when speed is reached. Anyone with a roofrack/bars will know about the whistling as well.

i agree with pete as that is what i was going to say, it will be to do with re vamp and extras they put on them to turn them into police cars.

now i was once told that police cars are offiaclly rejected cars from the makers you when ones that have failed the tests they do before they leave the factory as the police adapt them themselves… now as i write this i know it sounds a load of ■■■■■■■■ but i was told this of a very good source that i cant remember. :blush: :blush: :laughing:

Pete is right. It the extra external fittings. As a Radio Ham, my car bristles like a porcupine with 3 transmit antennae, none of which are particually discreet. and yes they whistle like hell.

At my late brothers garage they used to supply a few cars to Humberside police, occasionally they would come back for warranty work. The amount of equipment they carried as well, probably overloaded on the drive axle :smiley:

That, and the light bars probably make the extra noise.

Why do the police whistle? Because they don’t know the words! I know, I’ll get my coat on the way out! :laughing: :laughing: :laughing:

Makes perfect sense to me. I know the Royal Mail did it with the LDV vans they had. Used to arrive with big “REJECT” stickers on the windscreens :laughing:
