Most performance turbochargers today use a single gas ring for sealing the shaft. XR turbochargers utilize twin gas ring sealing. This feature dramatically reduces gas and oil leakage rates for both the compressor and turbine ends of the rotating assembly. Since the sealing load is spread across 2 rings, wear rates are reduced and seal life is also extended. To complement this, large diameter oil slingers are incorporated into the shaft design at both ends further reducing splash oil at the piston ring seal location within the cartridge.
