in my eyes it kinda kool to have a turbo timer... lol

but you will need one if you upgrade to a biger turbo with out water cooling.... thats for sure and even that big oil cooler and high flow fan!!!

theres my 2 pennies

I like your two pennies. The sales dude tried to tell me it had a turbo timer when I test drove the one I bought. I just smiled at him, and said "is that so..." and let him live in his little fantasy world. Actually our cars do take a few extra seconds to shut down, but it's because the TC-SST is configing for shutdown. You only see this behavior if you put it in park and shut down right away (which he did and thought he was clever).

They do have a turbo timer. It has turned on three times for me. I drove it hard then shut it down quite quickly and the turbo timer kicked in for 5 mins (roughly). Apparently because we have the cooled turbo the ECU decides if the turbo needs additional time to cool off and allows for that time. Most of the time it doesn't do it because of enough cool down time. I asked my local Mitsu dealer and a mechanic verified that to be true.

Are you sure that's a turbo timer and not simply the fans staying on or something like that?
Edit: The reason I ask is if the car has a true turbo timer built in as you suggest, it's the first I've ever heard of and it requires some pretty fancy electronics/ECU tuning. If the ECU can adapt and keep the car running based on how you drive, it must have some way in which to determine how you drove and equate that into a cool down time. There are two basic options for this, the car either has sensors that can monitor things like oil temperature, oil pressure, water temperature, maybe even turbo temperature in a very precise manner or the car monitors things like time spent at WOT, boost pressure used over a period of time, etc. Either way, it could mean a very expensive bill.

There is a guy on another forum I am on who put a turbo timer in his Lancer GTS. No, he doesnt have an aftermarket turbo...he just wants to make sure the engine cools down after he has driven to Superautobacs

I wanted to add to what ambystom01 said.

You guy's do know the difference between a turbo timer, and the cooling fans, correct?

A turbo timer keeps the engine running once your keys are removed which circulates, oil, and sometimes water through the turbo allowing it to cool down after boosting. Under high load the turbo get's extremely hot and needs time to cool down, but normal driving your turbo won't see these extremes. Turbo timers are setable from less than a min to 5+min. A normal safe and practical cool down period does not exceed 1-2 min. Remember this is with your car stopped, ignition off. If you set the timer much longer than that it's counter productive because your oil, and water temp will increase without the air flow that you have while driving.

The cooling fans running is to cool the water temperature, not turbo. when you stop there is no cooling airflow over the radiator which causes the water temp to rise. the cooling fan kicks on to keep the temperature below the point of over heating. The fans can even kick on when the engine is off, and usually do in the summer immediatly after shutting off a vehicle, if not the water temp can rise, and the expansion will cause coolant to drain out.

It is doubtful that it keeps the engine running, as it would not be a good idea if you pull your car into a garage, pull your key out, and have the engine run for 5 minutes without your control. If the car had an electric oil/coolant pipe, then it could cool the turbo down without the need for the engine to run.

You sir don't know how a turbo timer works.

It wouldn't be a bad idea, I guess if you had a pump to circulate the oil, and or coolant through, but I have not seen an add on setup like that, It could be done though, but it's easier to just let the car run a minute.

unless your really hard on it like just ran down the track or boosted down the street to your parking spot, you really won't need it. If you do drive like a bat outa hell then I would suggest you let your car run at idle for a min or two before shutting down. Over two min in the summer becomes counter productive as your car will heat up if it's not moving.

I do know how a turbo timer works, and that's why I assume that the R/A does not have one. My point was that it wouldn't be wise for mitsubishi to have that feature without owners knowing about it, so that the car doesn't stay running when the driver intended to shut it off, and park it in an enclosed area, or perhaps even when the owner is really low on fuel.

no neng, that is just the fans dude, no car i have ever heard of comes with a turbo timer a true turbo timer (meaning the car keeps the engine running even after you remove the key), your just keeps the fans running do to the explanation further above my post, when shutting the car right off before letting it cool for a second

fan does not equal engine

I'd imagine it might be a bit difficult to install a turbo timer with the anti-theft system.
