I Know you all say don't bother, and with good Merit for most applications... but my usage of my vehicle for work is a tad different to most...

i don't often have time to sit and idle the car, ( i do when i can) but often i will drive down the highway to a meeting place ( i am newspaper Photog remember) and jump out and do the shoot and go again...

or i will have to fang it across town to try and get a shot of something going down, or a whale sighting off the beach or who bloody knows what! so i just don't have time in these instaces to do that... and the times i have had to fang across town ( previously in NA vehicles) i have pushed my friendship with the local establishment!

now to my question... i have the Brandt removed... so i am told by the previous owner... but have an aftermarket immobilizer... this should hook up as if it were on any car that has an immobilizer fitted yeah??

also.. those of you that have them or have had them... any brands or features i should know about??? seen some apexi ones cheap on ebay... are they copies??

Too long, didn't read.


No.



You don't need a turbo timer.

[Morgan]

Whilst it is a good idea to let you car idle for a bit before turning it off, it's not completely necessary.

I've heard that the engine's cooling system will continue to circulate water through the lines once the engine is shut off. Unless your car is very heavily modified, this is sufficient.

I'd suggest putting the cash towards something more worthwhile.

you don't need a turbo timer. as morgan said (and alex in less words) it's not needed as our cars have water cooled turbos. the reason you know what they all say is because it's true, having one fitted would only be for show

from Subaru:

"TURBO COOL DOWN PROCEDURE

FHI's position regarding this is that it is not necessary to perform a "cool down/idling" procedure. Our current 2.0L turbo engine has a far greater cooling capacity and, coupled with technology advances, makes this practice no longer necessary. This explains why information about cool down is not included in the Owner's Manual.

The heat contained in the turbo charger will begin to vaporize the coolant at the turbo charger after the engine is stopped. This hot vapor will then enter the coolant reservoir tank which is the highest point of the coolant system. At the same time the vapor exits the turbo charger, coolant supplied from the right bank cylinder head flows into the turbo. This action cools the turbo charger down. This process will continue until the vaporizing action in the turbo charger has stopped or cooled down."

and thats why mine is sitting in my tool box ever since i got it off you aek

[Jovi]

I have a turbo timer on my B4. I had it sitting around so i used it and the brant was removed thats the only reason....

[Cam.]

Don't bother, As others have said. Unless a turbo is only oil cooled then it's not going to do anything except use extra fuel as it's idling for no reason.

Thanks AEK, appreciate the response... and Alex... i know you like to be the devils advocate, but sometimes its good to understand why you need or not need something...

now that i know that i have nothing to worry about it wont bother, but i did think for a bit there i was an advocate for needing one...

I only like to help people who help themselves.

I don't spoon feed.

http://www.mrtrally....ce/whytimer.htm Good ol' MRT

[Dimeb4g]

But you see Alex I Was prepared to help myself... I knew all about the benefits of one, in a normal application... And I respected what people say about not needing them... By asking what I asked I found out a fact based answer that I wouldn't have found myself... There is no spoon....

You do not need to sit and idle your car. It shits me how people say this...
Other than cranking the car over letting the engine start nd give it about 5 seconds for oil to be happy, there is no point idling the car at start up.
Just start driving and keep it under 2500/3000rpm. This process will warm your gearbox oil up to (something not happening sitting there) not to mention other moving parts.

I wrote a long post on this ages ago on rexnet and i cant be bothered finding it, but its pointless. unless you get in and floor it (which is stupid) then there is no need to sit there with the car longer than about 10 seconds.
Take it from me, i had a my00 wrx and she went till 396000km original engine/gearbox/turbo and pretty much everytime i got into her (partly cause she had a loud exhaust and i was working early mornings back then) it would be in, start engine let clutch out and reverse out the garage and drive.

/rant.

As for your turbo timer, from what you wrote i still dont see why you would need one :S Just dont go full boost then turn it straight off.

Stuff the boi racer mods and spend the money on sorting out your tranny/aftermarket immobiliser Frankenstein-ness.

if i have to boot it down the road to an accident scene, or to a photo of a local polly or a bunch of greenies chained to some trees or something like that... its arrive, action, go go go no time to worry about the car... which is why i thought that a timer would be of assistance... but i am leaning towards not bothering...

haha yeah thats the plan... i can get a timer cheap... and in my defence, it was out of a specific requirement to consider one... not **** factor... unlike remote starting and all that jazz! lol

[glenisanutter]

To everyone who thinks a turbo timer is just to cool the turbo.
By keeping the motor running It also keeps oil pressure to the turbo bearings until the turbo had slowed down to its lowest possible rpm hence saving the bearings! Cutting the oil feed to a shaft that is spinning so fast is what causes problems!
This is far more important that the temperature!

[ams]

Im not sure he means turning the car off at 20 psi...

[Scuba-Roo]

i'd assume when the oil pump stops pumping the oil, oil thats sitting around the bearings doesn't magically disappear and leave the bearing bone dry.

sorry mate, but this is not right.
I worked on a race team a few years back, we had an experimental turbo made specially for us by garret, it included an rpm sensor so we could directly measure the speed of the turbo. Anyway, the speed of the turbo would go from 300,000+ rpm at full boost to about 50,000 rpm in less than 1 second when the throttle was snapped shut on the engine dyno. A tiny factory b4 turbo would probably accelerate and decelerate even quicker than this, basically, by the time your engine has reached idle speed when you stop the car, the turbo will be at its minimum rpm, its not going to get any slower letting the engine idle. When you shut off the engine, a plain bearing turbo will be completely stopped within a couple of seconds.

The idea behind letting the engine idle before shutdown came from the days of oil cooled turbos on big trucks that ran at 30-40psi most of the time, where there would be no natural circulation of coolant after shutdown. The red hot turbo would bake the oil to the bearing surface in the turbo and cause premature wear.

Basically, unless ur exhaust manifold is glowing after an extended period of thrashing, there is no need to idle the motor.
Excessive engine idling causes the oil to be washed from the cylinder walls and wears your rings quicker.
Just look at modern turbo diesel engines, they are basically on boost 95% of the time, and there is no need to idle them.

[Cam.]

Turbo timers...lol.

[TSG]

But it makes you look cool when you leave your car idling loudly in the maccas carpark and walk in to get a big mac. That way everyone knows you are a douche.
