[Euro] Turbo Timer

[jl88rl]

hey,

Ive seen a few ppl with turbo timers in there euros, would just like to know do they leave the alarm and everything else (eg, auto lights as key retracted, windows still active until doors open, etc.) still working once activated?

Thanks

[yfin]

Ive seen a few ppl with turbo timers in there euros,

Any of them members here? And what sort of turbo are they running? ;)

[stephen8512]

that should be the case because essentially the car is still running, its just that u dont have the keys in the ignition and its counting down till it has to shut down the engine, thus the name turbo "timer"
but why would u get a turbo timer for a NA car? waste of money IMO and not very beneficial.
but i guess if u also have the money and if u want that wank factor, then go for it

[Tobster]

Don't know about other states, but technically turbo-timers are illegal in SA.

[destrukshn]

yeah turbo timers are illegal same as remote start.
you are supposed to be in your car when it is started or very close to it.
something like 5-10 metres or something.

[DLO01]

Sorry not that its on topic. But for the people that think 'turbo timers' (even though the name states it) are only usefull to turbo cars your wrong. If you car is NA and you use it on the track or even give the car a canning on the road. Its a good idea to let it cool down a little before shut off, hence a turbo time is very helpfull to a NA car.

[Tobster]

You'll still cool down more effectively driving around due to increased air flow...

[JasonGilholme]

but if you're pushing your car hard right before you pull into your drive and turn your car off, the oil and water pumps shut off and leave the oil and coolant sittin in an engine that will still be building up heat.

At least when your car is idleing its still pumping the fluids around and cooling to some degree.

[stephen8512]

cant u just stay in the car for 5 mins while it cools down or something......

[UNLS1]

hahaha turbo timers on N/A cars now ive herd everything....

maybe its just a 4cl thing..... i dont think the 6 or 8 cyl boys would ever be that sad!

unless they have turbos bolten on!

[stephen8512]

ive seen 1 euro with the apexi pen timer.
but in all honesty i cant see why u would want a turbo timer on an NA car
im sure theyre useful to any car but all im saying is, i just personally think a turbo car would get the most benefit out of it

i believe in gettin bang for ur buck.....and to me a turbo timer on my euro would just be a waste of $$$ when u can use that money to get a rear sway bar or something more beneficial

[DLO01]

Have I started something? Lol.

Just research the reasons for needing a Turbo timer. The reason is applicable more so to turbo cars but also NA cars.

Have a search on the net.

[stephen8512]

yeah true true
thats why apexi pen timer is called NA/Turbo timer
although of course u can use any turbo timer on any NA car

but hey by all means if u want a turbo timer and u think it'd be beneficial, then go for it :thumbsup:
was just stating my point of views is all :D

[gelo]

or u can just do a cool down lap

[Tobster]

but if you're pushing your car hard right before you pull into your drive and turn your car off, the oil and water pumps shut off and leave the oil and coolant sittin in an engine that will still be building up heat.

At least when your car is idleing its still pumping the fluids around and cooling to some degree.
And if you've been pushing your car that hard, then you should back out of your driveway, and go for a gentle drive around for 10-15 minutes...

[albii]

omg..does anyone here actually know what a turbo timer does?
1. total waste of time and money on a na car..why not put a boost gauge in too.
2. turbos oil feed runs very hot oil. the timer allows the hot oil to escape the turbo preventing heat soak on the turbos gaskets and bearings..
IT HAS NOTHING TO DO WITH COOLING DOWN....how does a running engine cool down ffs.

[DLO01]

Lol at Albii

A turbo timer is a device designed to keep an engine running for a pre-specified period of time in order to automatically execute the cool-down period required to prevent premature turbo wear and failure. After a period of driving when a turbocharger has been working hard, it is important to let the engine run at idle speed for a period of time, allowing the turbo to run down in speed and cool. At the same time the lubricating oil from the engine is able to circulate and cool so the turbine won't burn the lubricating oil that would otherwise be trapped & choked within the charger. In Natrually Aspirated applications a turbo timer is also usefull, the extra heat associated from continuous high rpm associated with Circuit racing and/or spirited driving can also cause the oil to choke.

Does this need further discussion???

Thats a perfect explanation........might add that turbo timers are a waste of money, :D

That will work very well but if you've got time constraints then that won't be possible. Its just a convenient thing to have.

[Tobster]

That will work very well but if you've got time constraints then that won't be possible. Its just a convenient thing to have.
That's like saying, "I didn't have time to check my tyre pressure," or, "I didn't have time to get it serviced."

Turbo timers are still illegal in some states, regardless...

[ECU-MAN]

yeah turbo timers are illegal same as remote start.

something like 5-10 metres or something.

so you have a better chance of chasing it down the road. or to witness the devistation you have just created ??? :)

[Catcha]

Having a turbo timer is convenient, but driving the last 1km off boost eg for a turbo car is sufficient time to let it cool down.

Take for example, current wrx 2003 and onwards, From What I have heard nobody can fit a turbo timer to make it work with the Brant alarm, its been and issue from when people have tried when they were released.

People live with it and adjust to it.

I was going to fit a turbo timer to my MY99 but driving off boost and and letting it idle for 10secs after is good enough for me.

What turbo timer manufacturer did you quote this from? What does it mean by "cause the oil to choke"?
Bull(cough)shit

Turbos run hot. After turning off your car, the oil doesn't not circulate because the engine is off. The oil trapped in the turbine will burn because it is in contact with the hot surface. Trapped oil = choked.

otherwise known as heat soak...kills turbo seals and bearings.

[CUL8R]

anyone with a turbo, go out right now and thrash the shit out of ur car for 10 mins
pull into a pitch black street/area and turn everything off and open the bonnet. the turbo is glowing!!!!!!!
u need oil to continue to circulate and give the turbo enough time to cool so to not lessen the strength of the turbo parts (i dont know turbos so im not gonna explain this in too much detail)

in theory the time for a turbo timer to be on for is the amount of time the turbo glows after giving it absolute hell. something like that anyways

a turbo timer will have use in NA cars, but why do it? its hardly as important as for turbo cars.plus if ur giving ur car hell i doubt ur gonna pull in and bam turn off the motor and park and leave, do u not know what happens to your brakes when u put the handbreak on when they are hot? just sit in the car for an extra minute or two if ur paranoid.

Yeah I know about turbo’s aaronng, I'm talking about NA. A timer will not benefit you one bit in NA. The timer when put in a turbo car is there because of how highly stressed the turbo's get and thus generate huge amounts of heat, NA cars just don't get that sort of excessive heat build up due to a thing called a radiator.

I know people will disagree but if a car normally running at about 90 degrees gets thrashed and then turned off immediately what kind of temp do you think it will soak to, 100? 110? 120? what? Let's say it gets to 120 after 10 mins of soak, as soon as you start the engine again new water will be circulated through the engine and cool it down to 90 again

Say you run your NA car hard. And then you reach your destination. You turn your car off straight away and run indoors because you have something urgent to attend to. What happens to that heat? The radiator is not removing that heat because coolant is not being circulated. The pistons, rings and block are hot because you just had a nice taste of high RPM. The parts are all in contact with each other, at high temperature and there is no coolant flowing through to remove the heat. What happens?

What engine block runs at 90ºC? You're quoting coolant temperature. The temperature of the parts that are in direct exposure to the combustion that occurs is much higher. In the combustion chamber itself, you're seeing over 400-500ºC. At the engine oil, you're seeing over 100ºC. The problem is that if you leave your engine off at high temperature, there is a chance that the high temperatures at local spots will cause uneven metal expansion. Remember, the block is much hotter closer to the combustion chamber. After a hard drive, it is very important to let your engine run to circulate the coolant to remove as much heat as possible.

Yes, if it is a street-driven NA car that does not see hard acceleration, then the turbo timer is a waste of time. Heck, if I was driving normally at the normal RPM range of below 4000rpm, I'd just turn the engine off after I reach my destination. But after hard driving, it is important to let the engine cool. I don't like turbo timers. I'd rather wait next to my car while it idles for 3-5 minutes after a track session. Personally I see turbo timers on an NA car as a waste of money. But I STRONGLY feel that letting your engine run for a few minutes after a hard drive is a good thing. I agree with you that the turbo timer is a waste of money. I don't agree with you that letting an NA idle for a few minutes after a hard drive is pointless.

[msnealo]

All fair points raised aaronng.

[poid]

Say you run your NA car hard. And then you reach your destination. You turn your car off straight away and run indoors because you have something urgent to attend to.

then you are an absolute muppet, as you should have simply taken it easy the last minute or two of the trip.

Besides which, i would love to see how hard people actually manage to drive on the streets to have a heat soak problem when stopping their NA cars!! Are you guys doing a time trial to your driveway or something?

All theory aside, in practce a turbo timer is rarely needed on modern turbo cars during daily driving, and i would say never needed on an NA car during daily driving. Talking about race-track type examples is simply not relevant.

the oil circulating is for lubrication not for cooling..
GET THIS RIGHT..OIL CIRCULATING IN TURBOS DOES NOT COOL ANYTHING...
FFS ..OIL DOES NOT GO ALL OVER THE TURBO IT IS ONLY CONFINED TO THE CORE....(CENTRE SECTION).
and can someone please tell me how hot oil pumped from engine through core of turbo does any cooling...
the only way to cool a turbo is to stop driving the car a timer is only used because when a car is idle it is not producing boost and its not feeding hot iol into the turbo and what ever oil is in it has time to exit it because if hot oil sat in the turbo it would damage seals and bearings.(heat soak ffs)
everyone please ,hot oil does not cool turbos.

[CUL8R]

did i ever say the oil does the cooling!?!?!
i mentioned u need it circulating to give the turbo enough time to cool.

[Omotesando]

The correct thing to say (and someone already mentioned it) is that the turbo is literally glowing hot after a bit of thrashing. So the primary concern is it will burn the stationary oil, which will inturn seize the turbo's internal.

The other thing - oil DOES cool the turbo. There are oil cooled turbos, and there are also water & oil cooled turbos. Most of the newer turbo cars are water/oil cooled but the oil always has a role in cooling down the turbo's internal rotating parts because as you can imagine, coolant cannot run inside the turbo that is spinning at 1-20000rpm. Coolant helps the cooling further by running parallel to the hot metal in a separate water line.

In fact, oil helps to cool the engine as well as the transmission and the power steering. That's why transmission fluid and power steering fluids are oils and in circuit use vehicles, you need the respective oil coolers for them.


As for NA/Turbo Timers on Naturally Aspirated cars. OK, everything has been covered here to death already. I would say it can be useful but not as useful as on a turbo vehicle. You don't need a turbo timer on a turbo car, you could just drive around slowly or idle for a few minutes sitting in it. I didn't had one on my modded turbo car before lol.

But if you're late to work or a meeting, some people always on a rush might find it useful, even on N/A cars. Hell, even humans doing gym exercise needs to do warm up and then a gradual cooling down period set by the machine. Its always better when the changes occur gradually! Turbo Timers in general just looks ghey and ricey in an NA though, that part I would agree. But some others put a gauge (water or oil temp) on the A-pillar on an NA anyway.... Each to their own.

But since Turbo Timers are illegal, and it does not have a huge benefit, why put one in? The only other thing which would have enticed me to put one on especially on an NA is if my car was highly modded and the turbo timer also has Drag Timing built in as some of the BLITZ or HKS ones have....

[msnealo]

Nice Omotesando nice

[albii]

sorry Omotesando but oil is a lubricant and NOT a coolant.
thats why there are oil coolers and transmission coolers because the oil or lubricating oils runs so hot.
and if the oil in a turbo served to cool it then why do we need turbo timers to let the oil drain out of it ? and why does it cause heat soak?.

[aaronng]

The oil doesn't "drain" out of the turbo if you use a turbo timer. The flow of oil around the engine and turbo is maintained so that the oil does not overheat and break down in the turbo.

Anything that absorbs heat is acting as a coolant. Heat has to go somewhere and does not disappear by itself. If it is not too hot like in an N/A engine, the heat can be released into the atmosphere (block to atmosphere). If it is too hot in a trapped enclosure like the cavity in which the engine oil flows through in a turbo (which is hot), then the heat might not be able to escape quick enough before the oil starts to burn and form sludge.

Think of it this way. If you move your hand across a lit candle's fire, it doesn't burn. But if you moved your hand very slowly across or left it above the flame, your hand would feel the pain. Same as for the turbo. As long as oil is being circulated, the heat in the hot turbo is absorbed by the oil and passed back into the sump before too much heat is absorbed. In the sump, the small volume of very hot oil added to the large volume of hot oil results in a very small temperature increase. Plus, the oil is being passed through the oil cooler and also pumped up the galleries where heat is also removed by the engine coolant lines (which in turn is cooled by the radiator).

um.. it sure does..the turbo has an oil feed that is fed by the engine oil and is fed to the turbocharger when it begins to boost, and then back to the engine at a constant flow.
When the turbo is not boosting and left idle the oil simply drains from it and that is why a turbo timer is used.
otherwise the excessive heat resulting from the extremely hot temperatures that the turbo's core reaches would result in burning oil in the core reulting to what is known as heat soak.(the cooking of the seals and bearings )

When the engine is running, the oil pump is running. When the oil pump is running, then oil is flowing through the oil line that runs to the turbo. The turbo doesn't need to be boosting to have a supply of oil being fed to it.

Wow! This thread has blossomed. Good discussion though.

Though the topic starters question has not been covered unfortunatly. ;)

Hmm, if the engine is running with the timer on, that means the immobiliser is not activated. I guess you could stil have the door alarms and shock/glass break sensors still working while the car was running.

you've just jumped from one subject to another..and you also know what i mean...and it does need to be boosting hence why a turbo timer is used .
(when the car is idle the turbo doesn't get an oil feed.)

what exactly do you mean by "when a car is idle"?

Do you mean when it is idling, or when the engine is turned off?

The turbo is fed oil any time the engine is on.

[albii]

idling.......if the turbo was fed oil all the time then tell me why we have turbo timers ..car idling and not boosting allows the hot oil to drain from the turbo and therefore not damage it.

[albii]

do you know anything about turbos? cos i've owned a 95 lancer GSR, 93 liberty RS TURBO and a forester GT.

[albii]

yes , like aaronng said the oil disperses the heat from the core of the turbo a little but it is mostly for lubricating...my arguement is that oil does not cool the turbo. and it doesn't.

[DLO01]

idling.......if the turbo was fed oil all the time then tell me why we have turbo timers ..car idling and not boosting allows the hot oil to drain from the turbo and therefore not damage it.
When the motor is idoling oil 'is' circulating.

The reason for use of a Turbo Timer has been covered previously.

I don't care what cars people have owned in the past. That dosn't mean you automatically know anything.

[aaronng]

I've been browsing through turbo oil line kits and the lines run from a port off the outlet of the oil filter. Since the oil filter is having a flow of oil all the time from the oil pump, I also believe that when idling that oil is flowing in and out of the turbo via the oil lines.

[coladuna]

I wonder why people are even arguing the need for a turbo timer on a Euro when even my turbocharged WRX doesn't come with a turbo timer, which makes me think it's pretty much a waste of time fitting one on a modern turbocharged cars, let alone a N/A car!
How many people drive all day long as if they are racing on a track?
It may have some purpose for track driven cars,which I don't care about, but for street application, I wonder how many people will actually benefit from it.

just because a factory car doesnt come with something doesnt mean its a waste, thats stupid logic.

the fact is if you have a nice fang in your wrx then turn it off straight away without driving a little more sedately to let the turbo cool down and get the hot oil away, your turbo will quickly die.

LOL, people are too lazy to just drive gently for the last 1-2km back before they reach home. Silly. I'd rather drive gently. If I was on track, I'd have a cool down lap and then either idle the car (coolant is hot enough that the radiator comes on) or to go on the roads outside the track and have a gently cruise to have the air blowing past the radiator (even more effective).

[Omotesando]

Albii - I'm sorry to inform you but a Turbo Timer is barely a timer that keeps the engine running/idling for a period of time. I don't know what kind of function or miracle you 'presume' it performs when its installed 'that will keep oil running in the turbo', but unfortunately it doesn't do anything more than a change of the dial on the oven clockwise, so your turkey will bake for another 15 minutes.

Oil always runs through the turbo even not on boost. If it doesn't, then everytime your turbo spools up you'll be hearing screeches.

Also, oil I agree isn't mainly used for cooling but to say that it doesn't cool is very unrealistic. In phsyics/chemistry, anything that is running at a lower temp next to a higher temperature component, will absorb heat. Heat always transfer to the cooler side its a law of nature.

The fact that there are Oil Cooled Turbos on this planet already proves you're not grasping the central idea...

Have you ever owned an Oil Cooled Turbo car? Check out some of the old Saabs.

2ndly, on a race track, one of the main reasons why people increase the engine oil sump size and with fins inside and outside, is because more oil means engine runs cooler, the fins outside dissipate heat better, while the internal fins plus larger capacity gets rid of oil starvation problems.

[vtec_jet]

great discussion ...

chance a few N/A drivers are gona be havin turbo timers now .. lol

My DIY turbo timer: A 5 minute egg timer. I stop my car and start the timer. When it goes "Ding", I turn the engine off.

Please name a turbocharged car that comes with turbo timer from factory. I have not read a single word of warning in my owner's manual about cooling down the car before turning off the ignition after a hard drive. If there was a chance of any damage being done to the engine, I think they would've mentioned it.

WRX, WRX STi, Golf GTi, Polo GTi, XR6 Turbo, S15 etc etc don't have a timer from factory, and N/A cars surely won't need one. Simple as that.

[Omotesando]

Good point.... if its important then it'll be installed from factory.

On the stock WRX 1997 I tested once, on the side of the door it did say - please let car cool down after a spirited drive though. Didn't really see it on any subsequent WRX's I tested (I go and test cars all the time hmmm if I'm interested in purchasing it). Haven't tested the 2.5L WRX however - pigs nose.

obviously u have noidea what will happen if u dont let your car cool down..
rather than forcing it to cool down with sudden tempreture change. (shutting it off)..cooling it with the gradual decreasing tempreture is wise. (letting it run for about a 1-2 or too.
if there was no benefit out of it.
why do bignames HKS,trust,apexi etc spend lot of money developing these products.

BUt yeah...IMO turbo timer on an NA car is a waste. You only drive it hard every so often....and for that minority of time just drive around the block till the car cools down!

[thenozman]

Sorry guys but i am not really seeing the point to this discussion.

A turbo timer is designed to ensure that a turbo charger is given a chance to cool down and that any oil and water in the turbo charger doesnt cook.

Think of it this way, trash a turbo hard and you can get the turbo to glow. If you were to shut the engine down without allowing the temperatures to normalise two potential problems emerge:

1. The turbo will cool down too quickly which may lead to the turbo housing cracking, exhaust manifold cracking and excess wear on the turbo seals and bearings (i.e. the differing metals in the turbo will cool at differing rates);

2. Oil sitting in a housing that it at 500-600 degrees celcius will cook, this would could cause the oil to turn to sludge pretty quickly leading to choking of the oil lines and journals in the turbo, thereby leading to bearing damage from oil starvation.

The above problems are inherant to turbos due to their high operating temperatures.

I dont ever remember seeing a n/a car this hot!!!

Sure you can get a n/a car hot but if you are driving that hard you shouldnt be on a public road and you ought give it a cool down but nowhere near the amount of time required by a turbo. I am not saying that a cool down for a n/a car after a thrash is not required, but you would not need a cool down after say driving home from work of to the shops normally.

PS. Most manuals for turbo cars do say to give the car a cool down. I've owned a few. However, with the advent of water cooled turbos the need for a cool down after normal driving (i.e. no excessive boosting) is deminished. Anyway since when has it been the case that just because a manufacturer doesnt tell you to do something that means that it isn't required.

I think the most stupid logic is the fact that some people are considering or even have installed a turbo timer on a N/A car.
Please name a turbocharged car that comes with turbo timer from factory. I have not read a single word of warning in my owner's manual about cooling down the car before turning off the ignition after a hard drive. If there was a chance of any damage being done to the engine, I think they would've mentioned it.

WRX, WRX STi, Golf GTi, Polo GTi, XR6 Turbo, S15 etc etc don't have a timer from factory, and N/A cars surely won't need one. Simple as that.


you obviously do not really understand how your car operates.
if you believe that turning your car off after a hard drive without cooling it down wont damaging it, you are a douche and do not deserve a wrx.

]']obviously u have noidea what will happen if u dont let your car cool down..
rather than forcing it to cool down with sudden tempreture change. (shutting it off)..cooling it with the gradual decreasing tempreture is wise. (letting it run for about a 1-2 or too.
if there was no benefit out of it.
why do bignames HKS,trust,apexi etc spend lot of money developing these products.

Very simple. Because they develop them for people who race their cars?
Stop wasting on money on stupid rice gadgets.

You obviously don't get the point.
No idiot drives around on public roads like that to require that sort of treatment. No wonder I have one and you don't.

so youre saying noone with a factory turbo car ever drives it hard?

you truly are an idiot
