---AutoMerged DoublePost---

the s475 i was looking at has the specs as listed
High-flow S400 model, with compressor flow over 98 lb/min. Will service 900+HP. Also commonly known as an S475 and S375.
Wheel Dimensions: Compressor: 74.7 mm inducer, 100.8mm exducer, with exclusive Extended Tip Technology. Turbine: 95.5 inducer, 87.9mm exducer. Cast in Inconel 713 for high-temperature operation.
Housing A/R: Compressor .63, with 5.0" hose-type inlet, and v-band-type discharge. Turbine: 1.32, with 'divided' volute, featuring 'T6-style' turbine inlet flange (4.438"x2.75"), and quick-release v-band discharge flange. Cast in ductile iron.
This is the model that's dominating the medium-frame turbocharger market. With 'direct-fit' compatibility with existing 'T-' and 'GT' series units.
