So I'm purchasing a 91 Talon in January. It's fully rebuilt and all. But the turbo timer in it cuts out so the kid just took it out. I was online looking for another timer but a friend told me it's a waste unless I'm running the car hard or at a track which I won't do. So what's some other opinions. Turbo timer or no?
Are turbo timers necessary if not running hard or at a track?

Basically, a turbo time will allow you to take the key out, lock the door, and go in while running cooling down your turbo. It really is not needed, I usually sit in my car for a minute or two before shutting it off. After hard driving, its usually between a minute to two to cool down the turbo. Its not needed, but you can get an ebay one cheap, and they work.

I already know what they do. And I figured instead of sitting in my car I could just time it. But I'm not too sure if it's honestly worth the money for a timer and the harness.

Here is the question you have to ask yourself. Is it worth keeping a fully rebuilt car safe with proper cool down time? As you said your not going to drive it hard or take it to the track. Im assuming it will be a DD so really its not needed but its up to you. personally I would because even after a long drive you can heat the oil up to the point of, what we call it in transports, cokeing the oil lines. which is where the oil turns to slug and restricks flow to the turbo in turn hurting the turbo because of insufficiant oil cooling and lubrication. just my two cents.

Well I was leaning towards getting a timer because I have the image in my head of me being in a hurry and forgetting to let it cool down. So the timer will save my wallet and my enginge and all. Any good timers out there for a 91 Talon TSI?

HKS is pricy but is great but even the ebay one work well its really what are you willing to spend the ebay cheap ones work but may not have a plug and play harness like the HKS ones. google reviews on them and find out the good the bad and the ugly on all of them.
I actually have one built into my alarm/starter from Zenesis its one of the most expensive I have bought at 300 buck but its something that is three functions in one.

I used to run them but nowadays it's IMO pointless. I haven't ran them in 3 years and 100,000 miles. I tend not to drive into my neighborhood/driveway or parking lots at full throttle. While I agree going full spool and shutting it down imediatly isn't the best idea. Modern oils and the fact most turbos are watercooled and have come so far since the oil coking problems of the 70's. I think a turbo timer is pointless.
I guess I'll add that, I've really never liked the idea of letting my car idle and heat soak until the fans cycle, like all turbo timers do either.

This is a good point. I think that oils have come a really long way. I ran ams oil in my evo once for over 20,000 miles and it was fine. And yes I sent it out to get tested. If you are going to drive the car a lot I recommend AMS oils if you are not going to put a tone of miles on but are going to drive the car hard (not that ams oil should not be driven hard) I would go brad penn.

If the turbo is water cooled there's no need for turbo timing. Although it is a good idea to let the car idle for a minute or two after doing some hard driving or just getting off the highway. Think high EGT's.
Now if the turbo is oil cooled only, turbo timing should help with the longevity of the turbos lifetime.

Got a GReddy one and I use it as a voltmeter. Don't know why but the sleep time when set in auto mode can climb up to 7 minutes after "kind of normal driving" !? Now it's set at 2 minutes. 
The only annoying thing is people telling you: hey your car still running !? Than you say: with that 3" exhaust, I still can hear the car running in the shop, do you think I really forgot ...

I only mentioned the coking problem because it still happens even with todays oils. I work on transports and they are only oil cooled but this can still happen on a oil/water cooled turbo. There are hundreds of variables but with todays sythetics very rarely with it ever happen. Im just stating facts from experience. In the OP case I would run one because it is a freshly rebuilt car and why not keep it running more efficiant longer is all Im saying.

I put many many miles on my DSM over the course of many years with no turbo timer and had zero problems with turbo longevity.
Be smart. If you are driving the car hard let it cool down a bit before you kill it. If you are almost to your destination spend the last few minutes of the drive just cruising out of or at low boost to keep temps lower.
As said above water cooled turbos and oils have come a long way.

I had my old FWD with a 14B with no TT, and like above, if I drove it hard I would just let it idle for a minute ot two.
I did learn one thing though. Usually why would you drive it moderate-hard? Because you have to be somewhere quick. If you're running late and giving her a little beating, then you arrive to your destination and realize the time you gained now you have to sit in the car and idle it.
Look around if you really want one, I got my HKS with a 1G harness for $40-$50.

It is mentioned in my Evo's owner's manual (which of course comes stock with a oil and water cooled turbo and factory filled with Mobil 1 full synthetic) that after hard driving it recommends letting the car idle a min or two before shutting it down - so take that FWIW.
With that said, my GReddy TT in my Eclipse stopped working and I haven't been concerned about replacing it. I used to have it set for 1 min flat, but even that was annoying because my car shakes so much from the cams and hard bushings that it would set my alarm off. The only way to stop it was to turn the shock sensor down to the point where slamming a fist into the car wouldn't set it off.

The best and cheapest turbo timer is to drive it like a granny for a few minutes before you get to your destination after doing some hard pulls. Then you will not have to sit in your car for as long of a time.

When I was going to school in Pittsburgh I was late just about everyday. I didn't have time to sit in the car to let the car cool and was very thankful for the greddy turbo timer I bought to use as a voltmeter because it didn't take up valuable gauge-pod space.
On the return run home I took it easy the whole way so when pulling into the driveway there was no need to have her sit there and idle.
Do you need one? That is up to you based on your lifestyle. Not shutting down right after a romp is pretty much necessarry, how you achieve that can be done with or without a T.T.
