I have just come over to the dark side and bought myself an Evo 8 MR300 
What is the crack with turbo overrun timers? I understand that after a hard run you'd want to run the engine for a short period to cool the turbo etc. How long for? And should you be doing this even if your last few miles have been sedate town miles?
Turbo timers don't seem particularly expensive considering what they promise to do/save. So do you use them?
The last turbo car I drove for any length of time was a Uno Turbo (1986). Built of tissue paper but solid engine that took continual abuse and shrugged of a completely frozen winter with no antifreeze in the radiator (mates car). Speedo once showed 155mph on the M1, with boost at 1 bar.

There's a little bit of difference between different ones - some integrate better with the alarm than others. Mine's failry integrated in that any attempt to move the car while on TT will cut the enging and engage the alarm/immobiliser. It also varies the length it times for depending on the treatmetn the car has had on the run out.
Mostly I just switch it off - as PS said - it's rare that you're hammering it close to home but it's nice for track days etc.
I leave mine off mostly and just engage it if I actually want the car to run for a while before switching off or if I need to take the keys out and leave it running.

I have one and find it's ok, I just switch the engine off and it runs along by itself for a minute or two, I usually lock the doors without the alarm unless i'm leaving the car for any length of time when I will wait for it and arm the alarm, I always figured that it might be fun to see a little punk get in and drive the car off for 20 seconds before the engine cut out on him and I caught up, dragged him out and beat him senseless.
Saying this, I don't think I would buy one, i've only had them on my cars because they have been there when I have bought the car, i'd save the money and just let the car run a little when you park up, or if you are just pootling around town and not really stretching the turbo you can usually just switch it straight off.

I run with one.
It's more of a reminder to be honest. And the car sits on the drive, so it's never really out of my sight.
I'd get one personally. Plus, walking away from a running car that then shuts down and alarms itself as you're getting the first round in* is rather cool.

TBH,the only time mine gets used is,when I need to jump out to lock the garage but want to take the keys out & leave the engine running.
Letting the turbo/oil cool a little after a decent run is just common sense really.A T/timer that kept the boost low/off when engine & oil were still cool,after startup would be more useful,imo.

I had the turbo timer option on the Clifford Concept 300 fitted to my FD when I had it, it was easy to use and I never had any problems with it.
AFAIK there are 2 potential issues with turbo timers.
1) If you leave it running on the street you run the risk for being done for "quitting a motor vehicle"
2) Insurers don't cover you if it is stolen when running on the timer (although some timers are linked in so that if the handbrake is dropped it cuts the ignition).
