Turbo timer
Exactly. Read the manual guys. You have something that is heated to around 1400^f and is supposed to spin around 200k rpms...it needs fluids pumped through it to disipate the heat after a hard drive.
They really are pretty worthless on water cooled turbos. If you bang on your turbo real hard i.e. tracking it/road course, then let it idle for a minute at most before turning it off. It totally isn't needed on a daily driver.

The manual says to cool it down, and I'de rather be safe than sorry. Also, I dont have alot of free time durring my busy week, so waiting in my car for 1-1.5 mins after a quick shot across the beltway a couple times a day isnt feesable for me.
After a quick shot across the beltway, there is no need to cool down a WATER cooled turbo. Turbo timers were made for heavily tracked cars and turbos cooled by oil only. When you shut off an oil only cooled turbo, the oil can just bake right away, thereby leaving you with a non functioning turbo.
I stand by what I said.... its a completely rice mod.
The use of turbo timers to shut the engine off some preset time after the ignition key is removed was needed in the old days. Early turbocharger bearing housings were only cooled by the lubrication oil of a running engine passing by the turbine bearing. If the engine was shut of when the turbine was still very hot excessive heat wick into the turbo bearing and seal area, cooking the oil to black carbon, causing bearing/shaft failure and heavy oil consumption. The newer (for over 15 years now) style turbo housings are water cooled as well as oil cooled. It is the reason you do not need to purchase a turbo timer.
One still needs to take a cool down lap at the track and perhaps should not stop at the top of a mountain pass to enjoy the view if you have been on the boost all the way up, but for the other 99% of the time there is no need to let the engine idle for a minute before shutting off ignition.
