Warming up engine?
Jus as a general rule is it better for my engine If I let it warm up from cold sat on the driveway or warm up under load at v low revs while driving?

I personally let mine idle for a couple of minutes first, then i will drive off whilst keeping the revs under 2-2.5k i only really give it some when my temp guage is halfway!

Just get in and drive off boost for a couple of miles until the oil is nice and warm. This takes a lot longer then water temp, so this is not a good indicator of how hot the oil is.
The only way to do this is via an oil temp gauge, remember to let it idle after a hard run as well.

How long should you idle it for??? i tend to stay with mine 30 secs if i've been taking it easy - if i've give it a thrashing i normally make it a couple of minutes at idle!

I only start "driving" mine after 7 miles minimum. water temp is pretty quick getting to temp but i also like to make sure my oil temp gauge is reading around 30 - 35 degrees. Thats me but i'm fussy

Due to the heavy duty materials used for the clutch (so it can handle the amount of grip the car gets), when cold you will notice a bit of clutch judder whilst changing gears when warming the vehicle. Once the clutch warms up the judder goes away.

I leave mine to idle until the idle speed is at normal, the drive it under 2.5 for 10 miles.

Seeing as I only keep mine for around 25K miles I see no need for cooling down Time is money (and you can look a right **** at petrol stations )

You are joking!!!! like i said i warm it up for a few miles, cool it down, Optimax only and serviced at the best garage in the northwest!!!
It would be a great car when i come to sell it!

I always drive the scoob straight away, but dont go higher than 2000rpm - it means im crawling at a snails pace for ages, but i get so bored just sitting waiting for it to warm up!! lol!
I always wait for the temp gauge to get around halfway, wait another 5 minutes and then boot it!
Then when im cooling it down, i just drive off boost at around 2000rpm for about 2-3mins, whether i've been thrashing it or not!
Cant do much more than that really!!

Unless you kerb crawl on-boost there's little need to let the car idle for a while before switching; off-boost driving serves the same purpose as letting the car idle. What you must do is come straight off the motorway or a good blast down your fav road and turn the car straight off.
Mine always gets left to idle anyway, as I find that by the time I've finished faffing around with the steering lock etc... its a couple of mins anyway.

I was always told to not let the car idle on drive when cold starting, as it doesnt do the plugs any good apparantly. Get in the car and drive off boost for a few miles. I have an oil temperature gauge and never rag it until i'm up to about 75-80degs.
It's up tp you though.

Shaun.

I also take it very steady after first starting in a morning. I leave it to idle for a short time before setting out steadily...
BUT - surely, you'll do your engine more damage by driving in too high a gear to keep the revs low? ie, you are making you engine work harder to maintain the same speed in a higher gear than a lower gear? (and when the oils not up to temp, surely this is going to be very damaging?)
I keep my revs below 3k for the first 5 to 7 miles - but I try to keep my revs around 2 to 2.5k in order to keep the load on the engine down.
I'm not a tecky - does this make any sense?
I've just ordered a Blitz r-vit to monitor everything, but it doesn't display oil temp, so probably not that useful for this. I don't want to fiddle with it too much (adding sensors etc) as it's a standard UK MY05 under warranty!

Apparantly it's down to the fact that on cold start it's throwing more fuel in, which isnt very good on idle for plugs or your cylinder bores!
In any case..... what ever is the good or bad to the nth degree, do what you see fit.

This is probably the nth degree for a standard car.... but I presume can be more logical if you are using bigger injectors.
All this was based on my old 500bhp RS500..... so may not be relevant here, even though the same theory seems sound.
To the other extreme, I know someone else who just rags the backside off his Scoob from cold and has never had a problem. In fact when the turbo was inspected (along with the engine) everything was fine!
