Whats a Turbo Timer Used For???

Stupid Newbie question but i ned to know :) Help me out :-P

After you drive hard, you can't just shut off the car because that'll screw up the turbos. A turbo timer keeps the turbos going even if you leave so that it won't mess up the turbo.

I have a friend who doesn't use a turbo timer, and everytime he parks, he has to sit and wait in his car for like, 10-15 minutes to wait for the turbo to cool down.

It's not neccessery, but it makes things alot easier, especaially if you're in a hurry.

wow thankyou.. ok but what are the price ranges for the turbo timer and installation???

Or is it easy to install it by urself???

To get more technical:

A turbo has oil in it - just like your motor. Now...this oil is very hot because well - a turbo is exhaust driven and exhuast is hot :D haha Now - when you turn your motor off the oil in the turbo stops - it just stops. So...all of nasty hot oil is sitting in your nice, pretty turbo - cooking it basically.

A turbo timer keeps the turbo spinning after you turn the motor off to protect your turbo and not inconveinence u by making u wait like Swonder's friend hehehe

And also, especially in spirited driving, the turbo is spinning very fast. That creates a lot of friction, which contributes to heating the oil.

Turbo timers are fairly cheap, around $100 for a Greddy I think. I have no idea about install cost, but I think you can do it yourself.

Yeah, i think you can do it yourself. I think its simple wiring. But I don't have one and I've never installed one.

actually there is no way to keep the turbo spinning after the car is off since its exhaust gas driven. and its not actually the turbo you want to continue spinning but the oil pump so you can have oil flow through the turbo. the turbo timer keeps the car running so that oil continues to circulate through the bearing area of the turbo to cool it down so oil doesnt cake the bearing because of the massive heat that builds up in the housing under hard loads pushing its rpm into the 100,000's and at levels near, above, and beyond the viscosity of the oil. when you just run it hard and shut it off this hot oil just breaks down into carbon deposits around the bearing(s) leading to poor circulation in the future, blown seals and eventually scoring and failure of the bearing. consider it the opposite of a remote starter....that starts the car up so its warmed up and ready to drive before you get there, the turbo timer leaves the car on and shuts it off after youve been in it to cool it down.

To clarify things a bit, you can remove the key from the ignition, lock your doors, and walk away. Many turbo timers have some sort of protection. Most of the ones I've seen have you set your e-brake, then if the e-brake is disengaged, the car will shut off.
