Why do I keep hearing that a turbo timer is not needed if the turbo is both oil cooled and water cooled???

Does it have something to do with the flow of the coolant going through the turbo???

 

I have never heard of that? Almost everybody I know whether oil/water cooled or just oil cooled put in a turbo timer. For the investment it just is not worth taking the chance.

 

ive heard/read it many times aparently the engine coolant does such a good job removing the heat even when the cars off you dont need to worry about oil burning "coching" inside the turbo

 

cheap version of a turbo timer if you dont feel like buying one. get out of the car, arm it, then use the autostart feature.

 

This is a true statement. Under normal driving conditions, you really won't need it but after a few hard runs, it's recommended. Why take the risk...it's an inexpensive way to CYA.

 

It is said that a turbo timer is not needed as much with a turbo which is both oil and water cooled. I assume it has to do with the coolant helping keep the temps inside the turbo down so at shut off after hard driving the oil is not as likely to "cook" inside the turbo. I have both a turbo timer and a water & oil cooled set up.

 

Realistically a water cooled turbo, especially if it is ball bearing, would not require as much time to cool down since it has less oil going to it to coke, water to take more heat away, and the water also acts as a heat sink after shutoff. If you were boosting and driving your car hard right before stopping then a 30sec wait wouldn't hurt though.

 

It's a $50-$80 investment to cover a $700+ part from damage, just get one.
