Is it necessary to run the engine for a minute or so after a hard run? I have heard for and against.

I always drive the last 5 to 10 mins after a hard drive at sensible speeds to allow the engine and brakes to cool to normal temps!

I had a turbo timer fitted to an Evo I had a few years ago so I guess there is some thinking behind it!

Turbo runs at approx 10 times engine speed so it gets pretty hot. When you shut down immediately after a hard run all the heat left in the turbo has to dissipate and, particularly if the oil is 'average', the oil will begin to disintegrate (or 'crack'), leaving carbon deposits etc around the bearings. Over time this build up of carbon will affect lubrication and destroy the bearings.

I have a turbo timer fitted to my Furby Vrs. I feel iam doing the right thing with it, although i still think you should drive steady to help things out more ie brakes etc.

yep thats the best way

never heard anyone say anything AGAINST it though ??

It says about running down in the vehicle manual somewhere, so doubt anyone would be against it

I usually let it idle for a minute or so after a drive to let it spin down and 'relax'.

Whether or not this does anything positive i don't know??

after a long drive (30mins or longer) I let it idle for about 30 seconds - 1 minute before switching off.

Why keep it running? Do you live at the end of a runway?

Modern engines/turbos will be fine after a few miles of normal running

Not a runway but i do have to climb 2 fairly big hills (one is a mile long and a dual carriageway) within a mile of my house. It's always fun to give it a blast up these hills as this is where the car really shines.

So yes, i'd say my turbo is cooking as i pull into my drive.

Then just give it a min to cool down

yup, always leave it a bit to cool down

i'm with everyone else on this, i give mine a gentle run into my street and leave it a few moments before engine shutdown to give it time to reduce in temperature.

All it takes is to pull up outside your house, and keep it running while you take your seat belt of ,turn the radio off and get your stuff together then turn the engine off just before you get out .

yeah. I have a similar thing.

I park, turn everything off, go out and close the drive gates, then come back and turn the car off

I always tend to give it 30 secs to a minute after i've stopped till i switch off.

Though at idle are able to generate much oil pressure to really keep that oil flowing around?

I can't think of any sane reason why you would want to not either idle it or run gently before shutting down. As it is, most of my journeys have a slow bit at either end for warm-up/cool down.
