How does a turbo timer work and also, is it required for the ZPI or Turbotoyota Kit.

 

A turbo timer is recommended for any turboed vehicle.

From Wikipedia, the free encyclopedia

A turbo timer is a device designed to keep an automotive engine running for a pre-specified period of time in order to automatically execute the cool-down period required to prevent premature turbo wear and failure. After a period of driving when a turbocharger has been working hard, it is important to let the engine run at idle speed for a period of time, allowing the compressor assembly to run down in speed and cool from the lower gas temperatures in both the exhaust and intake tracts. At the same time the lubricating oil from the engine is able to circulate properly so the turbine won't burn the lubricating oil that would otherwise be trapped within the charger with the turbine rotating at high speed.



Just cause I didn't feel like typing it out.

 

Couldn't have said it better. Some say you don't need them, but I would recommend anything that will help with the life of your turbo and car.

 

makes life alot easier... you dont have to sit inside the car for a couple minutes, everytime before you shut it off...

 

if the turbo is watercooled and you aren't always boosting its not to big of deal.. its mainly just after freeway driving, hills, racing ofcourse , etc..

i would just get one to be safe ,they are less than 100 bucks.. plus im kinda impatient so waiting a couple minutes in my car doing nothing and my ADD kicks in, but thats just me lol

also does anyone make a harness fo an xa/xb?? or do we have to just wire it in ourselves??

 

Even if your turbo isnt water cooled and your not boosting on it real hard a TT is not needed...
But as you stated a TT can be considered a security blanket for your turbo, so there is not build up of hot oil in the turbo or it's lines..

Nobody makes a harness for an xB, xA or a tC, you will only see a plug and play harness for factory turboed cars and even then they dont make one for all of them.. I know mine dosent have a plug and play harness for it..

 

or what you can do is get a remote start with a turbo timer feature. This will allow it to run say 3 minutes after you have removed the key at idle. I know one of the guys at work has his SRT4 set up that way using the Viper 791VX and I plan on doing it using my Python 990.

 

I fought and fought with myself about using the TT that was built in to my RS for the xB.. But I was just to damn lazy to push the buttons on the keypad to turn the TT on.. I even made a button in one of my blanks that was hooked to a 2nd remote... In the end I just bought the Greddy and turned the key off.. no buttons to be pushed.. damn im lazy..

I just installed a TT on my new car and got it fairly cheap off EBAY.. Its no Greddy or HKS, but it gets the job done.. If anybody needs the link, let me know.

 

i have your old greddy tt, and i love it... makes life a hella lot easier...
