With this in mind, would someone care to explain how it works? That is, more detailed than the previously-outlined explanations.

 

You need a Type R tatoo!!!

 

It allows you to remove the keys from the ignition and lock the doors, but the car remains running. YOu can't drive it away without the keys, though. Shuts off after a preset amount of time.

 

I hard run would be doing some laps on a track and then rolling into the pit and immediately shutting down with an oil cooled turbo. The turbo needs to be to the point of glowing red hot and then shut down like that. Not many people here drive their car that hard (but most think they do). Just a minute of driving at normal street speeds is enough to cool it down. Modern oils and extremely regular oil changes go a lot farther in preventing coking of the oil than a spiffy electronic gadget. But it's your money...



Shoot, my '83 Skyline GT-EX Paul Newman Series had a turbo timer from the factory. It also had a non-intecooled turbo engine from the factory so I guess it's all relative.

 

neat-o, like the electric cooling fan, eh?

 

i always heard it was to allow the oil running through the turbo to cool down, not the coolant...



not like i care, cost like $100 and i got it with my last engine rebuild, and it's pretty cool and a good conversation peice.

 

if you have an oil cooled turbo and turn it off the temp spikes, and the oil can "coke up". when you add the water cooling it keeps the temp from spiking when you turn it off, so you dont need a tt anymore

Yes, but the water stops circulating at that point too, and the very small amount in the turbo at any one time won't do much cooling just sitting there.



The thing I wonder about is, the oil will drain from the turbo almost immediately anyway. The oil pump isdn't adding any more, and the drain is gravity feed. Oil goes out right away, no more is added. I guess the litlle bit trapped in the housing is what "cokes" but most of the oil drains away.



I think they are a waste too. My engine temperature doesn't go any lower no matter how long the engine idles.

 

whatever --- i had one on my mr2 turbo which was oil cooled ... and then brought it with me to this car....

 

but you just said that the car came with it?
