Im new to the turbo world and was wondering what you thought of the turbo timers. I have been reading up on the forum for the last couple days and about 50% say go with it and the other 50% say it's a waste of money. I work with the Fire Dept. up in the mountains so there is a need to drive the car like hell going upwards of 100 in traffic and getting out of the car upon arrival. So I think I am going to try a turbo timer out the longevity of the car. What brand do you all recommend. Any other suggestions for improved performance?

Waist of money.



Turbo Timer FAQ

The primary purpose of an aftermarket turbo timer is to allow your engine to idle unattended for a user specified amount of time. This will allow your engine, specifically the turbo, to return from elevated temperature levels to normal temperature levels prior to the engine being turned off. This can prevent oil coking in turbochargers that are cooling by engine oil.

Are these necessary with Subaru Turbos? No.

June 2001 TechTIPS published by Subaru for Subaru Technicians states:

"2002MY WRX TURBO COOL DOWN PROCEDURE
FHI's position regarding this is that it is not necessary to perform a "cool down/idling" procedure, as was recommended with past turbo models. Our current 2.0L turbo engine has a far greater cooling capacity and, coupled with technology advances, makes this practice no longer necessary. This explains why information about cool down is not included in the 2002MY Impreza Owner's Manual.

The heat contained in the turbo charger will begin to vaporize the coolant at the turbo charger after the engine is stopped. This hot vapor will then enter the coolant reservoir tank which is the highest point of the coolant system. At the same time the vapor exits the turbo charger, coolant supplied from the right bank cylinder head flows into the turbo. This action cools the turbo charger down. This process will continue until the vaporizing action in the turbo charger has stopped or cooled down."

Which manufacturer is best? This topic is highly debated. There have been no reported consistent "bad" turbo timers on the market. Obviously, there may have been bad timers sold, but not enough to report as "bad" overall.

Are there any downsides to turbo timers? There have not been significant amounts of problems with turbo timers. It goes without saying that repeated use of turbo timers has obvious effects on gas mileage.

Are there other uses for turbo timers? Yes. A turbo timer makes a great tool to warm up your car during cold days. Jump in, start your car, set the timer, remove your key, exit the vehicle, set the alarm, and enter a toasty vehicle 10 minutes later. It can be a more appealing and cost effective option than conventional remote starting devices. It also eliminates all thought of remote starting in gear (though there are safetys for this on remote starting equipment) for manual transmission vehicles or entering a cold vehicle because you forgot to set the climate controls prior to exiting the vehicle the night before.

Where do I buy turbo timers? Every Subaru/Import performance store sells turbo timers. For purchasing, support your local economy or the NASIOC Vendors.

How hard is it to install turbo timers? Allow around 1-2 hours for install time. Professional installation, depending on your area, is around 0. This is one vehicle modification that is very simple and can be successfully accomplished by even the greenest shade tree mechanic.

How do I install turbo timers? Refer to the turbo timer manufacturer's instructions. For turbo timers without instructions, below is a link to some of the better known turbo timer installation instructions:
scoobymods.com instructions (with photos)
nasioc.com instructions (with photos) catered towards factory alarm users

Editors Note

This post was created because I wasn't able to find a good turbo timer FAQ. I came up with the text based on LOTS of searching here. Upon reading this you should have an idea of whether a turbo timer best suits your needs or not. The manufacturer is up to you.

If you find an error in this FAQ, please PM me with factual details and I will update this post. Responses such as, "I have XXX's turbo timer and it's great!" or "XXX's turbo timers broke after 1 month" are not appreciated here, that is what the Car Parts Review Forum is for.

Wow...OT, I'm also a firefighter. I'd say be very careful going 100 in traffic. That seems a bit unsafe to me...I take it you cover a large district? Are you running any lights? We are allowed to run blue only courteousy lights, and they don't allow us to break the law, only "ask" that that someone pull over. You don't go to the firehouse first, you go straight to the scene? Not trying to bash, just curious.

Sorry I guess 100 was a bit of an exageration. We are allowed to go 20 over the speed limit so on the hwy I go about 90. Responding to station or responding directly to the call depends on what kind of call it is. Fires / car accidents we go stations, medicals we go to scene. Are DEPT. we use RED/WHITE and a siren. Thats cool though that you get to use blue.

I got a deal on a black Apex'i and i love it for some reason that are more important to me than just the "cooling down" feature

-In winter i can start the car and let it run for as long as i want without the key on it and door locked (its impossible to lock the running car with the remote)
-I use it mainly to monitor my voltage so no need of an aditional meter
- and since its a turbo timer than i set it to 30sec only

here whats my install look like

Do you run that at 30 sec no matter how you drive it? Have you had any problems with it? I talked with a local dealer and they said if I were to put one in, don't go with the Apexi because of all the returns they had. Nice install job though. It blends in really well.

then 30sec apply just when i turn off the car with the handbrake on
so when i dont want to let it run i shut the car first THEN put the handbrakes so there is no countdown
or i can manually skip it to 0sec quickly

Gotcha. I understand, different states, different laws. There was rumor that we were going to only be able to run green lights. That would not be cool. In Illinois I believe, firefighters can run blue lights and only chiefs can run red. Everyone except for our dept chief drive to the station for a call. Good luck w/the turbo timer, I had one on my last Eclipse and it never seemed to work right(I'm assuming the person before didn't install it correctly?)

i had an Apex'i on my DSM.

i believe that you can manually turn it off once it starts to count down by hitting the button twice. i cant remember which direction though.

On these turbo timers cant you just turn the unit off or is it always on?

nice, there good cheap insurance, even if the turbo dosnt need it, try sprinting a while and then sitting down without walking around and cooling off, there good for the whole car imo

Subaru says that after an extended driving period or after a hard drive (such as after any form of racing), you should let the car idle for 30 seconds before shutting off the engine. Whether you actually want/need a turbo-timer for the car to idle for 30 seconds, that is up to you.

Did you guys get the Drive Magazine issued to all Subaru costumers?
They state in their mag that you must let subaru turbo engines cool down for longevity. It is the 2008, June IIRC, issue, and there is no exception to this notice.

funny thing isn't it?
