whats this i keep hearing about turbo savers? what do they do?
Turbo savers are nessarsary for prolonging the life of your turbo. There are two types, one that keeps the car running for a programmed amount of time, then shuts off, and one that runs while the engine is off for a programmed amount of time.
Dont the Stock GNs have one already?
No, as far as I know, there is not a turbo charged car that comes with one from the factory, they are all aftermarket. The automobile industry is not into prolonging the life of parts, if so, your car would be stainless steel (delorian), and that would put ALOT of people out of work.
If not what benifits do they give you and how do they work?
The benifits are from the cooling down of the turbo bearings. This helps coking and an imbalance on the shaft which at over 100,000 rpms even the slightest amount will eventually destroy it.
I have the preluber, it runs before and after. Before is key to saving bearings due to dry starting, and after is for the turbo to resist coking. It cost me $450 about two years ago, and now when I was looking to carry them, they are at $600!!!
I did a motor and new turbo, so the preluber was an easy choice. I like doing things once, and that was the ticket.
