Erm... Well sort of Dave.Originally posted by Cupra Dave
I know I do not have a turbo but what a turbo timer does is leave the engine running after you have been driving when you take your keys out,
leaving the engine running after the car has been driven hard allows the turbo to cool
I do not know about all timers but most (I think) can be adjusted to leave the engine running for different lengths of time depending on how hard you have driven the car
As with any metal the turbo housing expands with heat.
If the car had been driven real hard and the engine switched straight off then the turbo can cool too quickly, contract too fast and crack
I am sure there is someone here how would be able to go into more details but thats the basics
hope this helps a wee bitty
Yope, try to feel it 2 hours after you stoped the car. Damn hot!Originally posted by Steve
Bills totally right,
You can get turbo timer's on clifford alarms but i haven't bothered.
If you've given your car nuts before stopping give it a bit off a rest or you might find that your turbo is still spinning at 40,000 rpm with no oil feed! Causing premeture(?) aging of the turbo.
The buzzing is a secondary water pump that runs for exactly 10mins after you turn off the ignition.
Not many people know that engines actually get hotter after you turn them of for a period, no cooling, thats why your cooling fan sometimes runs when you turn off your engine.
I would'nt generally advise that anyone drive the car hard from cold... Get the temps up to normal first. Does'nt take too long.Originally posted by Surfer_D

How long do you guys wait before switching off the car,
If I drive hard I leave it for about 4-5min, if I drive it normaly not above 3000 rpm than I wait arround 20 sec. Is that allright.
P.S: can I flor my car if I turn it on and leave it for about 5 min runing on idle (the fan is already working) or should I drive it more safely for some minutes and than I can trash it.
