hi all how good are turbo timers and are they easy to fit and where is best place to buy one thanks
You dont really need a TT imo...just sit in the car relax, think of the great drive youv just had, then turn it off after a minute ;)
dont finish work till 1 in morning so would like to just get out and get to fridge for a beer
What sort of alarm do you have? If it\'s something like a Clifford you can get a timer unit on that as some turbo timers won\'t allow the alarm to arm. If it\'s built into the alarm it\'s all sorted :)
The best thing to do is watch the Temp on the PFC, I found the best way to cool it down is drive with low load for a few miles before shutting it down, BUT if you can\'t do this Stop the engine when you arrive then leave it for a minute then restart and let run for 20 seconds then shut off.
I Know it sounds sad but i went through a stage of watching the Water temp after i\'d been for a run, usaly letting the car idle for 2 minuits just builds up the under bonnet temp as its not getting the air flow through so it can increase the temp rather then lowering it.
My advise would be watch your PFC and play with diffrent stuff until you find some thing that reduces the Heat build up rather than Storing it.
Totally understand what you\'re saying Grizzly but I thought the purpose of the timer is for the oil to the turbos to keep lubricating it instead of stopping straight away?
It is, so you don\'t end up with oil coking up and clogging the turbos etc. Problem is you end up with warmer oil at the end of the 2 minutes idling that you would if you drive carefully for the last couple of miles and allow the oil cooler to do it\'s job so when you do finally stop the engine you\'re in a worse position IMO.
BTW I also open the bonnet for a few minutes after I\'ve stopped to help the heat escape a bit better :)
I guess electric oil and water pumps are the \'proper\' way to go so you can keep the fluids circulating without running the engine.

Yep you are quite correct the main reason is to stop carbon build ups in the Turbo, But when i have been watching the PFC i found the water temp gets very warm (around 100deg) which is getting close to killing water seals. So i\'d still tell you if you have a PFC before you fit a Timer do a few diffrent things and see which one brings the temps down better and i can tell you know it won\'t be letting it run for 2 minutes, All that does is build the heat up stuff like the Intake temp etc as there is no moving cool air.
The Proper way to cool it down is to run the car down, lots of moving air through with little to no Load on the engine this will cool it down better than abything. But you are right in saying the electric water pump is good too becouse that will keep the water circulatin after the engine is off, Combined with the Ign rad fan trick it would work very well.
The reason i say stop the engine then restart and turn off is becouse in doing this the water/Oil will absorb alot of the heat from the Engine and Turbo so it will become warmer then the fresh stuff in the Rad and oil cooler/sump, all you are doing is taking the heat out of the metal into the liquid before it has time to boil away change it for some cooler oil/water, if you where to just keep it running the Heat soak would keep the oil/water hot and start a visous circle.

Thing i noticed is no matter what you do with a stock Oil/Water system when you turn the Engine off the temp will always rise, the idea is to remove as much heat out of the Engine itself to start with then the Temp dif between the Coolant and Engine won\'t be as great and the temp won\'t go to Dangrous levels.
That\'s a very good point. Seeing the rise in water temp having stopped the car to pop into the supermarket say, there are \'hotspots\' around the system that a quick restart of circulation will help sort out. I\'ll have to try that :)

There should be some \'Thermo Syphon\' effect with the water and possibly the oil as well, so there will be some movement of water and oil from hotter areas to cooler areas. Although this will certainly not help the turbos, which really do need to see oil / water circulating until they have cooled sufficiently.
There are some intelligent turbo timers that change the after shutdown run time based on how the car has been driven - if it\'s been ragged just before you switch off it runs for a longer time, but if driven carefully, the turbo timer will only run for a few seconds / tens of seconds before shutting down.
I\'d still say unless there is Air movement through the Rad and engine bay leaving the car idleing will not help cool it down without long periods of idle, i have not left it for move than 5 mins but i can say without a doubt the Engine tends to heat up if you hammer it then pull up and Idle for 2 minutes.
I don\'t think you see what i am trying to get across, When a cars stopped the air flow is dramaticly reduced so the only thing thats providing air flow to take away the heat from the Rad is the Fans, Now if there is constant coolant flow through whill the engine is running the fans won\'t cool as efficantly as they would if the Water flow was stopped, So now with the amount of water in the Rad being cooled more Quickly and the Engine transmiting more of its heat to the Water that is Stoped in the water ways when you restart it and the cool water hits the engine in turn cools down dramaticly quicker, Thats Acording to the Power Fc hand controler. (BTW this is on an FD using the Ign Fan trick to help cooling, Fc\'s have to keep the engine running becouse of the fan set up)
Try it, Its the way to cool Fd\'s down more effectivly that Idleing for 2 minutes, but i still belive the Only real way to cool a motor down Quickly and effectivly is to Run it with no load on with plenty of air flow through, the Water temp does\'nt climb quite as high when you turn off. But thats just my Opinion if you have tried diffrent methods and feel that running for 2 mins is best then go for it, i just say watch your PFC.

Hi Grizzly,
Who is this addressed at? If it\'s me I\'m a bit confused cos I totally agree with you! That\'s why i said:
"Problem is you end up with warmer oil at the end of the 2 minutes idling that you would if you drive carefully for the last couple of miles and allow the oil cooler to do it\'s job"
I.e. driving with no/little engine load so air is passing through the oil coolers and rad is the better way of cooling the engine down than by leaving the car idling for a bit after stopping :)
My Commander is so useful in giving accurate information about what is going on, scary how uninformative the std gauges are...
Cheers,
Alex
ok thanks ill save my money, just a thort i have a switch under bonnet to swith fans on if i put that in car and switch then on when driving home would that do it
if the engine is hot the fans will be on anyway.
how come the fans don\'t stay on after you switch off the ignition..surely this would help to bring temperatures down after you stop even if the water/oil isn\'t being pumped?
I pulled up last night after driving gently (over speed bumps!) for the last half a mile from home, ran the engine for a minute or so. Went into the house, went back down a couple of minutes later as I\'d left my phone in the car and the apexi was showing water temperature of 123 deg. I then sat with the ignition on (fans running) for 3-4 minutes and the temperature slowly dropped to below 120 deg but eventually I had to leave it!?
Firstly, is this normal? and secondly, how would a turbo timer help?

That\'s the way the standard fan setup works, they only run whilst the car is on...
Because I\'m nice:

Found out that the one I have was fitted with fancy rubber heavy duty double sided tape. Found out when it fell off.
Any idea where I can get some fresh tape from ??? It\'s about 2" wide and you need about 3" of it
Like mine i use the same method as grizzly to cool mine down...leave the fans on to cool the rad water and then turn it on again...best way iv found with all this overheating BS iv been through the last 3 months!
