FAQ
Will 14961016100 fit my S475/S478/S480 build?
Yes—this housing is designed for 96mm S400/S410SX turbine wheels often found in S475–S480 builds. Always confirm your wheel and outlet dimensions before purchase.
How does 1.58 A/R compare to 1.45 A/R?
The 1.58 A/R typically lowers drive pressure and boosts top-end flow compared to 1.45 A/R, at the cost of later spool. Choose based on power goals and gearing.
Is this housing twin-scroll?
Yes. It uses a T6 divided (twin-scroll) inlet for improved pulse energy separation when paired with a matching manifold.
