Can anyone advise whether you need to leave the engine runnning for a few minutes (a la Lotus Esprit Turbo!) to lubricate the turbo turbines after a brisk run or not?

Also, any other operating points to note?

BTW - is there a rev limiter (and, if so, what's the setting)?

Thanks.

You will *definitely* want to leave the car idling for between 30 seconds or 1 min before switching off. This applies to ALL turbo cars.

On any turbo car you should let the car idle for a bit before you turn the engine off. If you dont the heat from the turbo's will bake the oil and you will have problems later on.

Yes - always leave the car running (or "coast home" without any boost) for at least 30 seconds - preferably about a min. or more.

Rev limiter is there (i've hit it), around 6750 or similar (I wasn't actually looking - you don't really get the chance when it's accelerating that fast!)

OK, thanks but what if you forget to let the car idle (or say, a copper "requests" that you "switch off your engine and get out of the car")?! Should you switch back on immediately or just try to remember next time?

Has anyone thought about fitting a Turbo Timer:

Have used one on my EVO – weird sensation of locking up the car and walking away from it while it is still running…..

Best regards

Fitting a turbo timer is fine, but it is illegal in this country to leave a car with the engine running, I believe.

The other issue with turbo timers is that they tap into the engine to keep it running without the key, this can cause problem for some car alarms and possibly make it easier to steal.

Hi Dakkon,

I will contact HKS to find out the following:

1. Is there a harness for a Noble?
2. What are the legalities?
3. How does it work with alarms?

The only other issue is where the heck to fit it!

Regards,

Lynton

There is some great info on the forum about running in and on going running. Does the factory not give all this info in a manual. If not is it worth a go "factory".

Or else we could start a separate topic on this and get every one to add there bit which will eventually become the manual.

But who will be the Editor . . . . now theres a power struggle.

Yep - it's all there in the 30+ page manual that comes with the car

As the manual has a different set of running in instructions to the dealer.

Manual - max 4000rpm, no full welly until after 250 miles.

Dealer - max 3000rpm, no full welly.

Going back to turbo timers and alarms, most can be fitted without interfering with the alarm.

But a car that can be left running whilst alarmed does not meet the Thatcham CAT 1 specification. This will almost certainly affect your insurance!

Re: turbos.

We recommend that you leave the engine running to cool the turbos, but it depends how you've been driving the car beforehand. After a gentle drive, especially if the last few minutes has been at low speeds thru urban areas, there's no need to keep it running. But if you've been driving the car hard, eg on a track, keep it idling for a minute or so before turning it off. Same goes for fast road use, obviously.

Hi Micknall (or is it just Mick?) - nice to see the factory on here more and more lately dishing out the advice.

All I can say is

My Audi Ur Quattro manual says the same thing.

Personally for the last mile or so (which usually equates to about 2-3 mins of driving) I try not to make the waste gates fisss - i.e. keep it under 2.9k or so.

It's no real bad thing, and I've only done one turbo in 100,000+ miles in the Ur so something must be right....

Reminds me of the manual in the old Metro Turbo - it specifically said that if you didn't leave it idling for 45 secs minimum, 2 minutes if you had been "larging" it the car "would suffer catastrphic failure very quickly" In those days they just said it as they found it!
