after having a 'discussion' with a friend, one seems to think having a timer running for a good 3 minutes is needed after a hard/long drive, whereas the other says ~30-59 seconds is fine.
i personally think that the drive through suburban streets to my house, and then 30-59 seconds is enough time to stop the turbo dieing from coking.
it's not like you (well me anyway, dont know about anyone else) thrash your car right up to the driveway, rip up the handbrake, and get out..
nor after a long country drive/cruise, etc.. you dont thrash it all the way home.
please elaborate as to what choice you made, and why.
cheers.
