Turbo Timer

[MAS_R33]

Hi,

When should you use a turbo timer?

I have a turbo timer installed (standard car running standard boost) and i only use it when i give the car a bit of a thrashing. Normal driving i dont bother with turbo timer.

is this wise? or should i always use it?

cheers

you only need to use it when you've been on boost just before you're turning the car off.

If you drive normally and stay off boost when you're getting close to where you're going, you dont need to use the TT as the turbo hasn't been doing anything

TTs are after-market gadgets. If Nissan had wanted you to use one, they would have installed them as standard items.

TTs are generally for idiots who can't control their right foot during the last km of any trip, and are then too impatient to wait with the car for a minute while the turbo cools down a bit.

[WazR32GTSt]

contrary to what blind_elk has aid, i leave mine on always. i give it 30sec after each drive regardless of how i've been driving

am i an idiot?

am i impatient?

no and no

i just care about my car...

you should too, astro_r33

I have the blitz auto timer... which decides a cool down time automatically...

99% of the time all that is needed is 10seconds...

If nissan were that concerned they would have installed turbo timers standard

I dont have a TT...

...I just take it easy as im approaching my destination, and usually wait about 15-20 odd seconds (Usually spent closing windows, sunroof, side mirrors) before switching it off....but i never let it sitting idle as you'll end up trapping a bit more heat due to no/less airflow.

exactly. letting it sit on the spot idling creates heat soak, which can raise the temp. if i fan it around close to home i usually just idle around the block to let it cool down.

Ha? Can you elaborate? I live near a big hill and when I climb it my car usually sits around 2000-2500 RPM. So the turbo is working slightly and needs bit of cooling (20-50 secs) so I just idel in my drive way If i have time or walk off with TT on.

[Nismo_God]

How can a turbo timer be harmful...so i just use it all the time....its not a pain in the arse to have it on...and it is helping....better to be safe then sorry.

[GTR_STEALTH]

I dont think anyone is saying a TT is harmfull champ!

Sir-D,

Im not sure what you want me to elaborate on? ...basically all im saying in my post is to take it easy as u approach ur destination and you wont really need a turbo timer.

And my personal opinion is that if you think a TT is gonna save ya then think again.

Thrashing your car then coming to a complete stop and leaving it on TT will NOT cool down the rest of your car like transmission etc...

[Kinks]

TTs are a bit of a wank, all that's needed is some common sense either drive gently and give it 10 seconds to idle before turning off or let it idle for 30-60 seconds and be done with it. Did this with my last car and never had a problem.

I do have a TT integrated with the alarm on my current car, this lets me be lazy and take the key out, get my stuff etc and then as I walk away I override the TT and turn the motor off then arm the alarm. Could count the number of times I've let it run the full 90 seconds (fixed) on one hand.

But isnt that related to any car, turbo or not as far as cooling the tranny etc goes?

[Kinks]

the point is a TT makes people think they can flog the car and then park it and leave it idling while they walk away.

a bit of mechanical sympathy goes a long way in ANY car, not just turbos.

You're prety much spot on the money there champ....

From Wikipedia, the free encyclopedia

A turbo timer is a device designed to keep an automotive 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 compressor assembly to run down in speed and cool from the lower gas temperatures in both the exhaust and intake tracts. At the same time the lubricating oil from the engine is able to circulate properly so the turbine won't burn the lubricating oil that would otherwise be trapped within the charger with the turbine rotating at high speed.

Ive seen on some TT's it says suitable for Turbo charged Vehicles and NA vehicles. I always go easy a few mins before reaching destination and give it a few secs when i pull up.

The shafts on most turbochargers spin in excess of 50,000 RPM and generate lots of heat. To keep your turbocharger's heat under control, most are cooled by circulating oil or water (coolant) around the shaft. The turbocharger's shaft is free to rotate at will and there is no way to stop the shaft from spinning after shutting the engine off. To dissipate and stabilze the heat in the turbocharger, most manufacturers recommend that a car be idled for a period of time after moderate to hard driving to allow the oil/water to take heat out of the turbocharger.

Failure to reduce the temperature of the turbo could result in the oil around the shaft "coking". Coking is basically the baking of oil, turning it into a hard substance that could plug your oil lines and cause oil "starvation", preventing proper cooling of your turbocharger and reducing it's operating lifespan.

If you take it easy just before you reach your destination.. a turbo timer isnt needed..

anyone who thinks they can drive hard then shut off their car immediately is stupid.. turbo timer or not
