I've browsed through the manual for this but didn't see anything.

What is the general consensus on this? I would have thought if you were flogging it, then let it idle for a while before shutting down? I remember a mate with an early Rex claimed it must idle for 2 mins or thereabouts before stopping.....

You don't flog any car then immediately bring it to a halt and shut it down.

Some people argue the effectiveness of turbo timers.. I say just try and drive with a light foot in the last 2 mins or so of your journey. Thats pretty much what I do if theres been a bit of spirited driving.

I've always made sure the last few kms are quiet.

Track days are harder and brakes need cooling as well, so I do a quiet few kms again before shut down. Mallala track here in SA is easy, you can just do a quiet loop into the town itself and back does the trick.

+1 on the toning down of your driving for the last few km's / minutes of driving.

Depending on how hard I've been driving prior to parking, I would normally let my car idle for approx 30 seconds before turning off... Sometimes a little more. After say a Nasho run, my car would be running for a good few minutes before I even think about shutting her down.

Yes there has been a lot of talk about how useful a turbo timer is on the newer turbo cars. At the end of the day, I still think it would be a useful mod & personally I'm looking at getting one in the not too distant future Just means you don't have to think about it when your in a rush.

turbos these days arent like the older ones where it was a definate to cool down.

i agree though give the car every reason to cool down after spirited or long hauls .. not only turbo but brakes as well..need cooling:wink:

turbo timers are illegal in some states...

It's a fine-able offence to get out of your car at a set of traffic lights ffs. There are 3 or 4 different offences the cops can use depending on the situation

From what I've heard that is only the case if it is not installed correctly.

IE - Timer should be connected to the hand brake... So should someone else get in the car, the minute the hand brake is released engine shuts off.

I believe this is mainly a safety thing, should you have an acccident you can over ride it to shut the car off.

I'm not 100% on this, but it's what many of my friends have done in order to keep their insurance companies happy etc.

sorry, rant wasn't directed at you - rule makers with nothing better to do than to screw around with everyone else's lives.

IMO, the turbo timer legality you mention is similar to the legality of getting out of your car at a set of lights: rule makers messing with the populace for no good reason

Turbo timers are not to be fitted to vehicles manufactured on or after 1 January 1972 (ADR 25 Anti-Theft Locks). ADR 25 requires that the normal function of the engine only occurs when the ignition lock is in the engine on position.

problems have occured in over turned vehicles where the driver has been unable to turn the car off ....unconscious, dead, what ever.. they can be dangerous in the wrong place, wrong time scenario..

so the handbrake excuse doesnt wear unfortunately..

my neighbours use to hate my Turbo Rs2000 ..with 2 minute turbo timer

Spoke with STI man at my recent service. He said there has never been a requirement on any Subaru that he is aware of to "cool down" after driving as they have an automatic wastegate that operates after the car has shut down.

My MY94 WRX had a sticker on the inside of the driver's door advising to cool the engine down after hard driving.

I'm a bit puzzled how operation of the wastegate helps cool the turbo down in a controlled manner (rather than the relative shock of turning the engine off immediately after a hard drive)? Any idea?

Turbo timers are crap in my honest opinion, they only create heat soak after you stop. Its better to have the airflow through the engine bay and drive the last few kilometres.

I tested this with a temperature sensor on the turbo and the turbo gets hotter while sitting idling.
