turbo timer would be your best option!!

 

always... even 30 seconds after not running it hard...

better safe, than sorry...

 

I agree with SoR. I do almost the exact same thing. On a related note, I let mine warm up to at least the point where the Temp. needle starts moving before I take off.

 

I have the optional guage pack, and I let the water temp needle start moving before I start driving, and I let the oil temp needle start moving before I start getting into positive boost.

 

Can you elaborate on this? Do you mean that the the turbo timer can be used to defeat the engine immobilzer when the car is running or also when it is shut down?

 

i always let my car idle.
i have a pretty long hill that goes down to my house, so i put my baby to neutral and cost it in my driveway. works like a charm. keeps me from waking up the neighbors late night to...hehehe.

 

Instalation of the turbo timer allows the car to run without the specially coded key in the ignition.... it has to in order for the engine to continue running with the key removed. So, your immobelizer is defeated.

I only idle after running the car hard, and that's more out of paranoia than anything. As was said above, driving into a parking lot or something should be enough idle time to "cool" everything down.

The turbo is water cooled, which pretty much reduces or eliminates the need for idling or turbo timers except for in some extreme cases. This article - http://www.spdusa.com/turbo_timer.htm - talks about Subies, but I bet some of this must apply to the Evo as well.

And think about all the turbo vehicles that are on the road. Most diesel semis, trucks, and cars, other cars like volvos, subies, old DSMs, whatever. How many of those owners do you think let their vehicles idle before they turn them off? If turbos were so unreliable that you needed to let them idle, would they be so prevalent on so many vehicles?

 

erm - im pretty sure our turbos are oil cooled?

 

Yes, I meant in addition to the oil. The turbo is lubricated, and hence cooled, by the engine oil. There is a water jacket around the center cartridge that also cools the turbo.

ahh ok.. thanks for the clarification!!

 

A friend of mine has a GMC Typhoon from the early '90s which as you know is turbo and he never cooled it down and no problems. He still has the original turbo. But everything else has broke. go figure.

 

My fiance idles it for a min before shut off.

 

I think that all things being equal, a turbo that is allowed to cool (30 seconds- 5 minutes depending on driving) will last longer than one that isn't allowed to cool before shutoff.

 

Thanks for hte explanation!
