turbo timer Options

[dagreat1]

I have a 3sgte with an up graded turbo (T4).... about how long should i set my turbo timer for?

[CaliJeff]

doesnt matter what kind of turbo u have, depends on how hard u push ur car. so if u gave it a good a hard drive, maybe a minute, otherwise i would set it for 30 seconds any other time.

[dagreat1]

even when pushing 20lbs?

even when pushing 20lbs?

besides just a turbo upgrade, what other mods do you have?

Lew - what?

DaGreat1 - post some pics seems like a nice little setup you have.

For reference - I set my timer for 1 minute if I'm driving around normally, 2 if I drove it hard.

And it matters a little bit what turbo you have because some are water cooled & oil cooled or both and different substances have different requirements.

[playr158]

water & oil cooled = don't use a turbo timer

oil cooled = use a turbo timer, 1 min is a typical run time

[Supersprynt]

Well, I wouldn't say DON'T because it sounds negative. It's not required. It's always a good idea to warm the car up before boosting and cool it down after driving.

[LewFX]

mines oil and water cooled but i still want to use the timer. usually i wait 2-3 minutes to turn it off

[Kadett]

It depends on all kinds of things.

When I get from the highway and have to wait a minute for a traffic light and then drive slowly/normal (2k rpm)I dont use the TT or max 10 seconds. When its green all the way to my house and have done some high rpms speeds its about 3 minutes.

3 minutes just seems like a waste of gas to me; especially with the water cooling.

i know ya didn't need to know half of that, but w.e.

you are going to do more harm with the safc trying to control 550s, then you will by running without a turbo timer. but to answer your question, i set mine for 45sec, and 1min20sec, if i JUST got done beating on it.

[playr158]

the purpose for the TT was when turbos didn't have the advancement of water and oil cooling.

With oil cooling alone, when people would turn off their cars, the oil pump would stop and flow ceases. This would leave a small pool of oil left inside the turbo journals, which from the heat would coke. Thus giving negative affects to performance & part longevity.

With the advancement to oil & water cooling there is no longer an issue with oil coking. Which brings the bandaid of the TT to a superfluous piece of equipment.

Although I do highly agree that you need to let your car cool off for a BRIEF period of time after a nice hard drive. really no longer than a min or 2 at the most. Reason why is most modern cars now have provisions for after you turn the car off, it keeps a fan on or other cooling measures. the longer your TT runs the easier it is to steal.

[Supersprynt]

There are safe guards against being stolen. First and foremost being the E-brake must be up to enable the TT.

[playr158]

i wouldn't like the E-brake as a safty..

only because when you are driving hard (IE track days/mountain runs)
you are braking hard, this brake heat normally lasts just as long as your engine heat.
when you stop you shouldn't be applying your e-brake, but leaving your car in gear to hold it.
having an e-brake applied on heated brakes can easily cause severe rotor damage.

any suggestions for another way to safeguard, for those who fall under that catagory?

for the most part, i agree that turbo timers are a ricer toy, but if you read the owners manual for an alltrac or mr2, they even tell you to let the car idle for about 120sec or so after hard driving.

I think "track day" is something few and far between to negate the safety feature altogether. That being said, your point is still valid.

Regardless of the ebrake light being on - without the key wouldn't the steering wheel lock?
