This might sound a very n00b and newbie question, but guys, what can you recommend as a general cool down period for the turbo? (14b)
For how long should I keep the engine running to cool it down?

Two cases:

1. Lets say normal use, cruising in town.
2. Highway use


Also, is there any recommended warm-up period for the turbo before it can be "punished"? :hmm:

Sorry, new to the turbo scene :)

cheers, all!:thumb:

ps: please, I know there are turbo timers, but can't get any at the moment, hence the n00b question. thanks.
 
In this cold weather I usually wait for the temp gauge to move before I pull out. Then I just keep it out of boost until the engine is up to operating temp.
 
When my car was stock, i would let it run for at least 30 sec to get the oil flowing then drive it real easy staying out of boost until it was at least 1/4 of the way on up on the coolant gauge. Now with my built motor if it is cold out i let i warm up for at least 2 minutes and in the summer i let it warm up for about a minute. Cool down i just have my turbo timer set to 1 minute 30 seconds and try to take it easy when I am nearing my destination so the turbo isn't red hot.
 
If I was driving the car hard at all, I'll let it cool down for 2 minutes or so. On long drives, I try to stay out of boost for the last few miles and then just let the car sit for about a minute. If I go on a really short drive without beating on the car, I'll just let it cool down for 30 seconds or less. As far as warming it up, I usually take about 30 seconds on a warm day and then stay out of boost for a little bit.
 
rather be safe then sorry, cause you dont wanna be messing up your turbo. But i will let my car warm up for 5 mins, here in jersey its been a steady 35 degrees all week long and nights obviously colder so i play it safe, and i don't go beating on the car right away when i pull out the driveway neither. Wait til the engine is warmed up to go playing around with it. For cool down periods, long trips on highways i would give it let it run another minute or two before i shut it off. however if im out beating on the car, i def play it safe and let it sit for 5mins. I would play it safe, it wont hurt the car to let it run for another minute for it to cool down or wait another minute for it to warm up.
 
id let the car warm up a bit before driving it for sure. just the same as you would any other car. cooling off is just intended so you dont just trun the engine off with super hot oil in the turbo. this is because the inside bushings/bearings are actualy quite sensitve. and if you always just shut your car off right away after driving it the oil will start to coke up in the center catridge. thats all that happens. its kinda hard on it is all. the owners manual in your glove box recomends 30seconds of idle before shut down. you could easily just pull your shifter into nuetral and coast the last two or three blocks to your drive way or work parking lot and then just turn the car off right away like a normal person. i have a turbo timer but i usally just coast a couple blocks and turn the car completley off right when i stop in the driveway
 
I let the car warm up to where the idle is normal at 800 rpms and theres no more lifter tick :p

Then I'll drive it very gently. I wait for temp gauge to be at the regular operating spot and then allow another 10-15 minutes of driving after that before I beat on it at all.
 
Oil temp gauge is a good instrument to look at when it is "OK" to punish, since the turbo is not the only thing you need to look after.
EGT's and oil temp during normal cruising dont differ that much from idle, so I personally dont see much point in idling the car "cool", assuming punishment has not taken place just before the parking place.
 
30-60 seconds of cool down should be plenty for just about anyone. This is far less important on water cooled CHRA's.

Also, I typically let it run for a few minutes before driving it and I ALWAYS wait until my engine is at opperating temp before I beat on it.


This is a golden rule to follow. Always wait until a car is at operating temp before beating on it. Unless you just like to break, or fix engine components regularly.
