Just wondering how many of us cool down the turbo and do it effectively.

I like to cool the turbo while driving home. I would shift at 2k and coast as much as possible (Drive half way down the block than coast the rest in neutral and so on for the next couple of blocks). Once I get to my house, I just idle the car for about another 20-30 sec. In my opinion, cooling the turbo while coasting is way to go since the car is at near idle and you're getting cool air.

When I get to the mall or other places, I keep track of how much approx. time I spent at a light and behind traffic right before the mall. Then when I park, I don't need to idle the car that long. Most of the time I only idle the car for about 10 to 15 sec since I spent a min or more at the light and drove at 5 to 10mph in the mall where my rpm never went higher than 2500K. Just remember, every time you are stopped at a light, you are cooling the turbo.

This technique has been very helpful for me since I don't have a tubo timer. If any of you have good ways to cool the turbo let me know. Thanks

 

You must install a turbo timer if you want to prolong the life of your turbo... dont do it by ear... dont take the risk... you can get those that are auto sensing so it sets the cool off time according to turbo temperature and they dont even cost more than $20 i think...

Fastest way to cool a turbo is to pop open the hood... or to drive around slow (under 2k RPM)

 

simevo is 100% correct. Driving at slow speeds (zero load on turbo, plenty of cool air) is better than idleing in the parking lot. The last 1/2 mile pulling into work is all 25 mph for me, and comming home my neighborhood is all 30 mph zone so the only time I worry about cool down is when going to the mall, out to eat, the bank...whatever. But on my daily commute it is not a concern.

You don't need a turbo timer, because you can judge how long to let it cool down yourself.
If you've been caining it then let it cool down for a few minutes.
If you've just been slowly driving around then 20-30 seconds will do.

 

Look at this....a New Zealander & a Bruneian (is that how you call it?) on the Evo board...cool stuff...


I do a similar routine....for everyday driving I'll coast to my destination at about 2000-2500 rpm for 30-60 sec. to cool the turbo down.

But after a more spirited drive, I'll just extend the cool down period and even let it run for about 1 to 2 minutes idle, before turning off ignition.

 

I do drive slowly near the end of my trips, but I still wait the additional one to two minutes or more. If it was hard driving, then more. It's not that much of a hassle for me, and it is a good conversation piece. Or it can just be good time to make out.

 

we run synthetic oil, or most of us do, The turbo in our car from what i hear is oil and water cooled, so sense such thin oil and the turbo being watercooled , cool down procedure isnt that big a deal, but it is always wise i would think to idle for a few seconds before cutting the car off (after a hard drive, not normal driving), or just drive normal for 1/2-1 mile after driving car......well thats my thoughts anyway.

 

Just don't beat on the car for the last few miles on the way home.

If the turbo exhaust housing is bright red Let it idle until it stops glowing.

Turbo timers work fine but they are not really based on turbo temputer.

Is our turbo actually water cooled (i.e. coolant cooled)? I've been wondering about that...

btw what's up 93civEJ1!

 

Yes water cooled. Most production car us water cooled turbos BTW.

VW
Audi
Subaru

 

yeah from i what i remember they are oil and water cooled...hehe...and wahts up to you too!! Badge looks great, thanks man...Had a tuff time getting the stupid thing to stick completely but that was nothing a blow dryer couldnt handle, by heating up the glue, pressing it, and letting the glue dry.

 

Just get a Turbo Timer, they're cheap, easy to install, and let you forget about idling your car around. Making a conscious effort to do this on your own might seem easy enough now, but it's going to get very tedious in the long run

 

I cool my turbo down by giving a quick spurt of NOS into the intake and it works.
Turbo cools instantly. Everytime I hit the button my EVO feels like its driving in 40 degree weather which comes in handy especially when you live in hot South Florida.

 

Lucky u for the NOS but i think rapid cooling for the turbo is bad since it causes the components to contract too quickly...

 

Turbo timer for 1+ minute(s). Peace...
