Here's some info I got off the net
This 69mm inducer flows a max of 105lb/min and is the largest turbo in the S300SXE family – the only modern technology 1000+hp midframe T4 journal bearing turbo available. Utilizing the latest generation aerodynamics, billet EFR compressor wheels, and uprated 360 degree thrust assemblies, the all new ‘SX-Enhanced’ turbos redefine performance and value for modern turbochargers.
BW engineers started with their 91S compressor wheel blade shape from the EFR9180, but trimmed to 75% for an increased airflow rate of 105lb/min. This all new wheel is packaged in a purpose built SX-E compressor housing with ported-shroud inlet and optional speed sensor port. A traditional Airwerks 80mm Inconel turbine and flexible housing options maintain consistency with existing installations. Smaller overall dimensions than the EFR9180 and higher airflow rates make this an excellent match for high-boost and high-power applications. Oil-Cooled Journal Bearing only.
