Oil Viscosity: Turbo

[onslow]

Hi Guys -

I have worked out the ZDDP and dino oil issues to my satisfaction.

Now, I am interested in your experience and opinions about the minimum and maximum oil viscosities for the turbo.

Knowing that the turbo spins at a much higher RPM than the engine...

What is the minimum weight it needs for protection vs. the maximum weight that begins degrading its spool-up rate and increases the effort to spin it?

If you have any testing info, track, or street experiences, that would be great to know about.

Thanks.

Steve
