Impreza Cool Down and Warm up
Discussion
Do you scream the nuts off, right up to your front door??
If not, just keep the revs below 2500 for the last 4 mins off your journey, and just switch it off.
The car will be cooler than sitting an extra 2 mins, with the engine warming on tickover with no air colling the rad.
Obviously, if you do drive hard to your front door (or come off the track withour a cool down lap), ticking over for 2 mins will cool it, but not as much as a cool down drive.

Mine has a rarely used turbo timer so if i've been giving it the beans it gets the last couple of minutes of the drive home taken easy and then around 1min30secs on the drive.
I have a point on my journey home where i start the ccol down, and find that works best for me.
ETA: I more likely to leave the Turbo Timer on outside the shops warming the car and confusing the local mongs than at home.

Sometimes i do but if i do then il leave it for a while until the cooling fan comes on, otherwise when driving normally il leave it for about 1 minuteIf not, just keep the revs below 2500 for the last 4 mins off your journey, and just switch it off.

Yeah I used to wait until the fan came on before switching the car off, but now I just tend to leave it idling as I take off my seatbelt, turn off the radio, gather my phone and wallet and step out of the car. Probably a minute max?
Of course if I've been for a fun run or just driven the motorway I'll give it an extra minute or two.

Just a quick point on the warming up process is not to go by the coolant temp gauge.
It is the Oil temperature that you want to rise in order to protect and lubricate the engine (I forget the temp for those with oil temp gauges..think it is maybe 80deg. off the top of my head before giving it full beans??) and ofcourse the coolant will gain temperature faster than the oil.
Only something to be aware of guys

I have an Evo 8, so a pretty similar engine and turbo in terms of the warming up and cooling down requirements.
The best piece of advice I can give you is to get an oil temp gauge. They are about £40 from Prosport (look like Defi's but a lot cheaper.)
It will tell you 3 important things:
i) When the oil is warm enough to use boost.
ii) When you've been going too hard too long and need to back off.
iii) When you're done driving, how long you need to wait before shutting off.

The problem i have is my Scoob is used everyday to get to work so living on a estate its not possilble to warm up the engine at 5am in the morning without upsetting all who live around me as its a bit on the loud sude,so for the first 4 or 5 miles i farely use the boost keep the revs low although i do cool down once at work i just drive slow for the last couple of miles its the only option for me i've not had any issues just yet.

I think a few people have some misconceptions around 'warming up' and I anticipated they may come up on this thread.Basically, there's no point in letting the car idle on the drive as it won't warm up anything other than the engine. The gearbox, brakes, diffs etc will all still be cold. You're better off driving a few miles carefully until everything is warmed up, then pressing on.
This isn't directed at you, Micron, as you mention you do drive off and drive conservativly until warm. This is directed at those people who might reccomend idling on the drive as a good way to warm up. (Also, as the engine is not loaded and only doing tick over revs it will take a lot longer to warm the oil than if you start driving. i.e. 10mins of idling will lift the temp as much as 30-60 secs of careful driving in my experience.)

This a good place to get gauges from. Loads of guys in my club use them. Really good looking units at sensible prices.

OK chaps - please tell me where I'm going wrong in my Scoob's driving. I'm sure you'll hate me for being some young t
t who doesn't deserve his car.
Start-up from cold: idle for 5 minutes while I smoke a ciggy. Then drive sensibly for 5-10 minutes before booting it (if necessary, not every drive).
General driving: Tends to be mostly motorway, whatever mph 3500rpm gives :P - slight overtaking up to 4000rpm briefly
Cooldown: 2 minutes(ish) off-boost, a minute cooldown
Tends to be my standard routine. My STi rarely gets driven in town - you'll probably see it lumbering its way down the M4/M5/M25/A3.
That alright? Or should I take more care in warmup/cooldown?
Bear in mind I run it on Shell VPower and change the oil every 5000 miles. I like to pamper it - even if it makes me look a bit sad.

Seb, you sound like you take more care than i do. From the sounds of it you have a good little routine so stick to it. t who doesn't deserve his car.Start-up from cold: idle for 5 minutes while I smoke a ciggy. Then drive sensibly for 5-10 minutes before booting it (if necessary, not every drive).

And yeah you jumped up little scrote, having a nice car at a young age, f
k you, fk you completely, fk off and get a Saxo.;)Sorry couldn't resist
Sorry to say but if your car is standard, or mildly tuned why bother with a warm up??? Just take it steady for the first few miles until everything is warmed up... Why bother warming up the engine when the Gearbox fluids etc are still cold when you drive off?
Also why leave your car to idle for ages before you turn it off? surely if you live in a residential area you will have drove for a few minutes in a 30 or 40mph zone off boost.
I didnt bother with a warmup or cool down on mine when i had it. Cover 60k miles running a aftermarket map, Nothing went wrong in the 2.5 years i had it.. all servicing done by main dealer.
