FAQ
What does the 0.95 A/R mean?
The 0.95 A/R ratio provides a balance between quick spool and high-end airflow, making it ideal for performance applications that require both responsiveness and top-end power.
What is a divided T4 flange?
A divided (twin-scroll) T4 flange separates exhaust pulses to improve turbine efficiency and reduce turbo lag.
Is this housing compatible with all turbochargers?
No, this housing is specifically designed for Garrett GBC37 turbochargers and compatible configurations.
Why use a V-band outlet?
V-band connections provide a tighter seal, easier installation, and better durability compared to traditional bolt-on flanges.
