Here's a picture of the compressor map of the new 69mm overlaid with the old 66mm:
The Borg Warner catalog I picked up at Sema lists the 69mm Super Core as part number 13009097051, it has the same 3.60" inducer at 91.44mm but a larger 2.72" inducer at 69mm. It uses the same 80/73 turbine wheel with the same 0.88, 0.91, and 1.00 turbine housing options.
The catalog lists the key features as:
*360 degree thrust bearing
*Integrated speed sensor port
*Forged milled compressor wheel
*Flexible compressor cover outlet options
*Pre-machined boost port
*Optimized compressor cover aerodynamics
In looking at the compressor map, it would appear that the map maxes out just less than
95 lbs per minute!
However, on the smaller single compressor map listed in the new catalog, they have added in the 58% and 56% efficiency contours that extend the map up to the 96-97 lbs per minute range, not sure if this will ever break 100 lbs per minute but it's still a nice big step up over the current 66mm.
