How many of you actually let your car cool down?

everyAfter installing my Turbo XS HPBC yesterday, I found out that this thing is deep in to boost almost all the time now. Even when I am not actually be in it. So my question is do I have to let this can idle now for 3 minutes after every drive? How many of you do let it cool down after not a beating, but a little bit of a 'spirited' drive?

I always let my car cool for at least a minute, even on easy drives. I'm getting a Turbo Timer soon, but until then, I'll be sitting in my car and letting the turbo cool properly.
Same here, I always cool it for at least a minute or two, and 3-5 when I've been gettin on it.
Most turbos today, including the one in the SRT-4 I'm sure, are water cooled as well as oil cooled. The water will continue to circulate when the car is shut off until the water cools down. I'm sure if you look in the owners manuel you will see that it says that no cool down is required.

Now, that being said...I still cool my car down after beating on it. I have a turbo timer, don't know that I would buy it again, and most of the time just let it control how long the car stays on for (reads boost). Sometimes I will leave it on longer if I have really been abusing it.

I have one but have not yet find the time to install it.

However, I do watch the temp gauge to tell me when it is safe to turn off the engine or expect some coking of the oil.
Before my TT, I would let the car cool for 1-2 minutes. Now that I have a TT, I have it set to a min of 30 sec and it builds time from there. Even on a nice spirited drive boostin 16psi, the car usually only takes about 45-50 sec. to cool down. One thing that you need to figure in is your time sitting at lights because cooling is taking place. My TT is pretty accurate IMO, because it reads boost and RPMs.

if i remember correctly it says no cool down regular driving, spirited driving 1-3 minutes

The reasdon they are water cooled is because most people dont let them cool down, this only helps it. BUt you should always let it cool down, even 20 sec at least.

Tha manaual does say to let it kewl down.
I have an apexi Turbo Timer that adjust cooling time automatically to how hard the car is run but it being water and oil cooled I dunno if it is really needed.

I always let the car cool down for 3 minutes. I find I usually drive somewhat agressivly, so I let it cool down for 3 minutes after EVERY drive.
I'm not really on the turbo that much at all, unless I feel like racing something. The Blitz is on 50 seconds auto mode A-S.
I have a nice long housing area to drive through, I go slow through there every time to let it cool down. Plus the TT for when we really go and play. Of equal or greater importance, remember to let the car warm up before you hammer on it, I sit in the driveway for 30 sec to a minute before I go anywhere, and wait unitl I am in normal operating temp before I play.
Ditto, on the warming up the motor.
For any sythentic type oil, especially the 0-50 racing version, it will require at least a 30-90 seconds for the oil to thicken to environmental temps and protect the motor.

This rule is a good one for any vehicle using thin velosity oil mix-to allow the engine to circulate the oil before operating the vehicle.

Almost fogot that to add that one. Kudos.
I only warm up about 20 seconds, but do not get on the gas until I'm at 200 degree area. Sometimes I feel weird sitting in my car for a few minutes, so I can't wait to get the TT. It will be the first thing that I add to my car that isn't GAS.

The best part is when you get out of the car and walk of while it is still running. The looks when it shuts itself off are priceless!!! :lol:
Just out of curiosity.... lettin the car idle for a few minutes everytime you turn it off,, wont that hurt gas mileage after a while?... especially if you just make short trips everywhere?... I know in my gasaholic Lincoln.... idling kills the fuel economy.. but thats 8 cylinders vs 4 and 4.6 liters vs 2.4.. and does the turbo even run at idle?
:wink: You should always warm up, and let the car cool down. Espacialy if you dont have a timer. At least a minute before you take off, and a couple of minutes after driving, without a timer. If some of you remember the rep that the early mopar turbo cars got, it was pretty bad. A lot of owners where complaining that the turbos where going out to fast. Well when they started asking people if they would let the car idle for at least a minute after driving, the majority would say no!
My SRT is my third turbo car. Second chy product. The labaron 4 door that I owned just had the engine gone through when I bought it. Used it as a cheep trans vehicle to make 115 mile round trip to and from work. Put 48k on it in 14 months. Not one problem. The other turbo car I owned was a 280zx turbo, with a fresh turbo and motor. Had that one for 2 years for work and play. Put 58k miles on that one, zero probs. What I am trying to say is that it takes a little commen sence.

As opposed to letting it cool down, I find that I just don't drive it like I stole it within several miles of my destination.

I originally posted this question because with my new boost controller, I am in to full boost with trying at all. More than 1/3 throttle and 2500 RPM's and it is in full boost. So to go somewhere and not boost it means going very slowly
