The Turbosmart B‑frame T3 66mm turbine housing with 1.10 A/R is a high A/R choice that prioritizes peak flow for top‑end power in forced‑induction engines. Matched to a 66mm throat and a T3 flange, this housing suits applications where maximum exhaust flow and higher power goals outweigh the need for the quickest initial spool.
