This may be a good candidate for a sticky?

I've been given a few tips from a Scooby owner at work, and wonder how many more there are.

I'm not only new to the Scooby, but to turbo charged cars so I think this is relevant to a number of people here. May be worth turning this into a bullet point list too

1. Don't drive full on until the turbo/oil has reached the correct temperature. This will take approximately twice as long as it takes for the cooling water gage to get to normal temperature.
2. Allow the turbo/oil to cool before turning off after a 'session'. This would be a 3 minute drive under normal 30mph driving conditions - or get a turbo timer. Else, the oil can melt parts of the turbo.

What else - or corrections to the above?

Thanks,

whats the normal temp for the water gauge?

madfiddler

I guess when it levels off and doesn't continue to rise?

Underworld

and where do u find that????

madfiddler

I guess the time it takes between the temp needle at zero, to the time where it stops moving up. Every car I've driven so far has a 'normal' operating temperature.

That's what this thread is about.. I may be completely wrong here, but any which way, I would like to know.

Underworld

suppose my car temp stops moving (and stays still halfway) after ive switched it on a morning then drove 1 - 1.3 miles

that means if i drive the same rate, it would take another mile for the turbo oil to get to the appropriate temp???

madfiddler

I think that's my interpretation mate, but I think we need some Scooby experts to help contribute to this. At the moment, I have no idea, but am worried that there are things like this n00bs like me should know, and don't...

and me!! least i have no worries on the turbo front i dont have one lol

madfiddler

yep

Any more tips please peeps?

I was told the safe assumtion is oil takes 3 x longer than water to heat up. 2 x should do it but play safe and go for 3 this is usually after around 10 minutes i find. Alternatively get a oil temp gauge!

And my addition is that the theory is that oil will bake onto the turbo-shaft if you stop after "violent abuse". But I've never heard anyone on here admit to finding that they've done just that...

5 minutes at 30 mph is fine, the air flow will rapidly cool things down, imho

And my oil temp is fine after 3 miles. water is usually normal after 1.5 miles !

P.S. the oil temperature myth is worth a look as oil at body temperature is pretty thin, i.e. 40 degrees, but it's your engine. I used to give mine a little bit of a go some nights out of work, but now wait till the oil has reached 50 degrees before opening the fuel taps...

Off boost until at least 80 degrees, normally 90. Takes about 8 miles or so.

I don't care if it's over cautious, it's what i've always done and will continue to do.

p1doc

70 degrees for me as that is what it says in the subaru manual-lamco gauges

After reading this thread, I'm never going to allow the revs to rise above 3,000, unless I have covered 150 miles!

It's obviously far too risky for the turbo!

With a dedicated oil cooler fitted, I have to drive it like I stole it for 5 miles to get to 90, let alone get it up to temp.

As a previous poster said, 5 miles at normal pace, keeping it below about 5k but not slogging it in too high a gear, will be fine. The ambient temp doesn't really make much difference in this country so don't worry about cold days, hot days.

You'd be surprised how quickly the oil will cool down too, so if you've left the car for a couple of hours, consider it cold and do the warm up thing again.

i don't use boost until my psi3 datamonitor shows at minimum 85 deg. the temp gauge shows normal from about 40deg so it does take about twice as long to reach normal running temp compared to the gauge.

It takes mine about 5-8 mile to hit 70deg at 06:00 in the morning when cold out side I.E icy. 3-6 miles to hit 70deg when not icy.

As I only ever drive 2.5 miles to work, 1 mile to the gym and 1.5 miles home I may as well sell the car for a sport

I do other miles obviously, but that's the vast proportion of them!

I give it some boost (not from completely cold), perhaps I am 'living on the edge' but its been fine for 3 years and its on 105k.

i find the warm up on my scooby to be the quickest out of all the cars i,ve owned

(i,m only going by the guage though)

I also never use the heater until the engine is fully upto temp

and i dont give it full beans until i,ve been driving on normal water temp for at least 2/3 mins (well i rarely give it full beans anyway as the old girl has done 112k - bless her)

sammydice

I viewed a 2003 STI at a main dealer on Saturday morning and asked him the same question as in my old 200SX I would warm it up and cool down via a turbo timer he said you didn't have to do that with a scooby rattled some technical sh*t off about the turbo that I didn't understand....

Good job I didn't take him on his word I didn't buy the car in the end anyway..

So just for the record you would treat a scooby the same as any other turbo car and warm it up then cool it down again afterward ?

yay - threads running again Interesting points being made - keep 'em coming

Just to add my 2 pence worth.

When i had my type R a few years ago i used to think that the car oil temps would warm up pretty close to the normal water temp guage on the dash.

How wrong was I!!!!

Now i have my Spec C with the defi's installed it can take a full 10 mins after the water temp is at normal before i get to 70c ish for the oil temp.

So would say never give it the full heavy right foot treatment until your car has warmed up properly. Not that it will break down on the spot or the turbo will fail if you did but its just good practise to do it.
Make sure you cool the car down after any hard driving but rather having to sit parked up for 5 mins after driving the car hard, its best to use the last couple of miles of your journey to let the car cool down as it will call down quicker as the car is moving rather then sitting in one spot.

All this is IMHO of course though.

I'm the same as most on here - never give it stick straight from cold (regardless of the car).

I have gauges fitted to my Type R and I usually give it 15mins of cautious driving befotre I open her up a bit.

TBH - I don't drive her that hard anyway but I would prefer to be over-cautios than going through engines and turbos etc.

Just be sensible and listen to the advice of experienced owners and you'll be fine.

Inevitably things go wrong but you live and learn and just deal with them.

10 miles minimum on the oil, it also depends on the exterior conditions, driving in snow could mean it takes longer but less in boiling hot sun
