Turbo Timers

[seventytwo]

In no way do I suggest after a hard drive you turn the engine straight off, but giving the turbo a chance to cool down by driving sedately for a few minutes before you stop will bring the temp down low enough for the thermosiphon to do its job and cool the turbo down with out risk of damage.

If we can all agree that water keeps flowing via thermsyphon after the car has stopped. I will data the log the water temp just before I turn my car off and check it 30 seconds later and see how much higher it is.

Damn this post has escalated quickly! Im with Azid Rush on this one, Sasha asked for the best place to put his timer and that's what we should be giving our advice on, not telling him its a waste and getting flamed for it. From what I can see and thinking of previous posts I have read similar to this it is going to be one of those never ending topics like, is blocking off the BOV safe? As Agent Orange said, it could possibly be a wank factor, but for 100 bucks and piece of mind I dont mind having one.

I too have seen this warning sticker on the door of a WRX, it says something to the effect of if you have been highway driving for an extended amount of time let it idle for one minute. Different turboschargers know, but again its for my piece of mind...

I agree

I think there should be a place for turbo timers in these cars, anybody that drives these cars, especially drive them hard and then get home and turn them straight off deserve to have there turbo completely shat themselves and then have there car implounded for being idiots

No wonder people have to replace turbos all the time, to drive a car like this requires a brain, and some ppl seem to be lacking

:D

OK show me 1 turbo which has failed due to engine being shut off after driving hard

In a closed loop system, the water will circulate naturally through the turbo, also after the engine is turned off, as it would otherwise turn to steam and blow your coolant out of the system (steam = roughly 1000x the volume of water)

Turbo timers are not needed on water cooled turbos, and are a waste of time and money.

Turbo oil supply is a much more serious issue on the 'T' and I have had a turbo fail due to lack of lubrication, so you should concentrate your efforts on improving the oil flow to the turbo, as the original Ford system is cr*p.

Let me repeat - TURBO TIMERS ARE A WASTE OF TIME AND MONEY FOR THE XR6T

Thank god someone has some common sense. Imagine all the woman and men who wouldn’t even know there was a turbo under the bonnet. If it was an issue then Ford would have a huge warranty problem.

The only Turbo's I've seen fail on the T4 have been as Ninka mentioned>>> lack of oil due to the screen blocking and secondly from debris from a failed piston.

NON from idling down.

So where should you fit the timer? In the box it came in

Yeh Ninka so you agree that oil and overall temp being the problem which is what I have said from the start about it being to hot for the water to cool it down enough to stop oil bake on the bearings.

I would assume most people would idle there car for around 30secs when they finish driving just gettin there stuff ready for when they get out of the car. But people also seem to believe with some posts in this thread that direct shut off isnt a problem after moderate to heavy driving.

My reasoning to this is =>

engine is stopped = No oil pressure flowing through the turbo this means that oil then bakes onto the bearings as its so hot and there is no where for the larger amount of oil to go as larger amount of oil is around the bearings when the turbo is being used. Even a putter will still cause the turbo wheel to spin . If left idling for half a minute reduces the amount of oil on these bearings as it drains back. Therefore less chance of baked oil on your bearings and turbo failure.

This thread just like all others about this has gone way off track as soon as someone steps out of the circle an is different people flame them, if people only listened to what was repeated over and over about mods on here, people wouldnt have figured out that modifiyin the entire intake system on the car with a stock tune wont cause over boost or problems to the stock tune. AFAIK people are putting turbo timers in there car for peace of mind an its more then one or two people puttin these on cars there are quiet a few out there. its a cheap investment for people to keep the turbo alot healthier with a greater reduced chance of failing.

[Ninka]

The only thing I agree with is that lack of oil will cause the turbo to fail.

Under normal conditions a Turbo Timer is not necessary, but if some like to fit one for peace of mind, I guess it will do no harm either (other than breaking the law and emitting more Co2 than necessary)

Even with some hard driving, how many times have you pulled up with screeming brakes and immediately switched off the engine? it is just not the normal way of doing things, and even 15-30 seconds of 'normal' driving after driving aggressively, will see the turbine return to near normal temperatures, and certainly will allow adequate amounts of oil and water to pass through the bearing housing to cool it.

have a look at the Nizpro video and see how quickly the turbine looses the red glow after coming off the gas, and that in a workshop environment without air flowing around it, and also an extreme 1200hp application.

As I said, if you want to have one, I see no problem with it, just it is not necessary, so I hope I can save someone from spending unnecessary cash on what is a bit of gimmick.

im glad im not the only one who thinks there a waste of time and money

I would like to hear what some of the site sponsors think

my tuner has said nothing about needing a turbo timer

[AGENT ORANGE]

There are people who use black track with Ts that use turbo timers Tom
