Folks,

I seen this guy outside my office today with a Scooby and was a bit surprised to see him walk away from his car with it running and no-one in it. :eek:

After about thirty seconds or so the car stopped though.

I have heard something recently about leaving turbo engines running for about thirty seconds after you stop the car .

Just wondering if this car had some fancy turbo protection device that allows you to lock the car and then leave the engine running for a set time then switch off?

Does anyone on this site know of any such devices or the importance of leaving the engine ticking over for a while ?

Cheers

It's a turbo timer Available as part of some alarm systems. I wouldn't worry too much about letting the turbo cool down unless you've been doing hard driving and pull straight off the road (eg motorway into a services) where it won't do any harm to idle for 30 seconds.

I've been recommended to get one fitted - but I think the logistics of it are a nightmare.... So would rather just use common sense and if I've been boosting in the couple of minutes leading up to my destination, I'll hang fire in the car on tickover for a short while and then turn it off.

I've also read on here that turbo timers invalidate your insurance.

I'm having a coolant run on pump fitted with my latest upgrade which keeps the coolant circulating around the turbo after switching the engine off.

And, if you've parked-up on the road or anywhere open to the general public (e.g. Supermarket car-park) you risk being charged with 'Leaving your vehicle unattended (with the engine running)' (Not sure if that's the exact legal term, but you get the gist).

its not so much the coolant round the turbo as more importantly the oil , this is what lubes the turbo bearings and if these aren't allowed to cool down after a hard run , i.e. turn engine straight off , the oil in the bearing will probably burn/dry out with consequential damage to bearings and seals eventually :eek: , thats why you leave the engine running at least 30 secs before turning off therefore allowing the turbo to cool down

Yeah that's true of the standard turbo that uses a journal bearing but not so important on ball bearing turbos.

Anyway, I find the best thing is just to drive easy for the last few minutes of a journey.

Thanks for all the replies guys

Will try a conscious effort in the future to wait a bit before i turn my engine off

Once again thanks :orb_clap:
