This is the standard S366 9180 but has a 90 degree compressor outlet. Using an 91.44mm exducer and 66mm inducer compressor, this turbo comes standard as a 90° compressor housing with T4 0.91 A/R single scroll open volute turbine housing. It is easily upgradeable to 0.88 A/R Single Scroll T4 or 1.00 A/R Twin Scroll T4.
The Compressor is a seven bladed 60mm inducer, 91.44mm exducer rated at 78lb/min. Recommended for use in high flow 450-750whp applications compressor housing is a 4″ inlet, 3″ outlet. Due to the extra flow capacity in this turbine wheel, we recommend using the 0.91 A/R for small displacement 4 cyl engines, and the 1.00 A/R for high boost over 26+psi. Journal Bearing and Oil Cooled only (water cooling and BB CHRA not applicable).
