yeah I checked there first and seen nothing.

I found this post from a couple of years ago on another forum,

"Jon from Full Race got me the answer. So FYI

-max EGT for the EFR turbos is 950C
-max turbine speed is rated in terms of "tip speed" and 560/ms. The specific RPM that 560m/s tip speed occurs depends on the diameter of the specific compressor wheel in question.
-oil pressure is regulated by the built in oil control orifice. Pressure range is stated as 30-100psi. we've had motorcycle and ATV customer engines at 15-20psi oil pressure and no issue surprisingly.
-bearings are m50 races with ceramic balls in aluminum cages (silver plated). Dimensional Tolerances are considered BW proprietary information and not shared outside of their internal engineering center.
-most of the EFR compressor wheels have 14 blades which corresponds to 2917 Hz (except the 6758 which uses a 12 blade wheel)"

but it just strikes me odd that, I had 40 PPM silver content and the zinc content in my oil was 1700 after 3000 miles, so probably 1800 for a VOA

prior to that, running Motul 5w-40 I only had a 3 ppm silver content and I was hard on the turbo for those 3 months I ran motul.

nothing changed between mechanical wise between the Motul and the RLI 5w-40.
