Turbo Timer Options

[3SGTE]

How long do you leave your Turbo Timer on for after a standard run in the 6GC? Sometimes after an easy run i leave the car running for 2-3 mins and even then i hear it bubbling for a minute or two... I also come down a hill to my house which helps cool her down... just wanted your thoughts

cheers

Normal driving: 90 seconds. If I drove it hard right before I stop, 2-2.5m.

I think your doing a bit of overkill

[Kadett]

If continueous driving up to 2500 RPM depending on temp gauge and what I did the rest of the trip 30-60 seconds.

Highway driving @ 3000-3500 rpm I would let it go for about 3 minutes.

High Power, as in continueous going up to 6-7k rpm about 5-6 minutes even more if temperature is very hot (110+ degrees C) But thats only happened once or twice.

1.5-2.0 mins for most driving, 3 mins max.
Idling car for too long is never a good idea.

[Supersprynt]

6 minutes? wow. Out of curiosity I googled recommended times but came up with no results.

Manual says 120 sec.

[3SGTE]

oh well, im not doing it too bad i guess. Better safe than sorry i always say, dont fancy blowing the turbo for the sake of a few minutes on the turbo timer

Can you please explain your reasoning behind this?

Like I said, happened only 1/2 times. The Turbo Timer (HKS anyway) has a built in RPM/Speed meter. It calculates (on auto mode) how long the engine need to run after ignition off. Nowadays when I do a high rev/speed run I just drive for a bit at 2000-2500 rpm with no boost to cool it down and then let it rest for the normal 30-60 seconds period.

It is wastes of gas, more pollution, dirty plugs, more contaminant in oil.
Cooling system also works harder (both turbo bearing and oil are water cooled).

[SlowCelica94]

Waste of gas? If you leave your car ideling for about 15 mins, you'll use less gas then the start up process.

As far as the rest of your claims, all those things would only even make a noticeable difference if the car was ideled for about 4-5 hours

OWNED ! lol

Make sure the turbo timer is hooked up correctly so the cooling fans will come on! I have my cooling fans hard wired all the time through a switch. or you could just unplug the coolant temp switch on the radiator. My switch went bad and car was getting hot at idle.
I cool mine for at least 1 1/2 minutes. After a hot day of hard driving, 2 1/2-3 1/2 minutes.

Comparing to starting up process is a moot point.
We are talking about how long should we idling the car in order to prevent coking.
Noticeable or not, it is the fact.
Longer idling causes more pollution and waste more gas than shorter idling.
You don't need more than 2-3 mins to cool the turbo down.

Well I compare it to the start up process because it'd you're not ideling the car. . .you shut it off.
Prevent coking? If your car on cocaine?
Longer idling with cuz more more pullution then longer idling, yes thats true.....and frankly common sense.

I don't see what you're aruging about anymore. Sorry, you were mistaken, I wasn't trying to be rude.


As far turbo cooling goes, a lot depends on your last few minutes of driving before turning off the car. If you're gentle before parking, 30 seconds will be fine. If you were driving real hard, give her at least a mile of nice easy driving to let your heat exchangers work. Then idle her for about a minute.

do a search on oil coking

[SlowCelica94]

I did, and still fail to see how this could effect even most 3S 6GC owners. Sounds to me like you've been doing more research then actaully work.

[Gary]

That's probably true, since my job is doing research.

Coking occurs when the turbo is not properly cool down.
It is one of the reasons of turbo failure. (CT26 included)

Here is a collection of what companies say about hot shutdown and oil starving.

45sec.

[SlowCelica94]

Yes, but we already have established that this certain vechile WILL be timed down. So oil coking isn't too likely.
