Why a 9-Blade Hybrid Turbine Wheel Is Better Than the Factory 11-Blade Design
-
Faster Spool and Better Response:
The hybrid 9-blade turbine wheel is lighter than the factory 11-blade wheel. This reduced weight allows the turbo to spool up more quickly, resulting in faster throttle response and improved drivability. -
Lower Back Pressure and Heat:
With fewer blades, the 9-blade wheel offers a larger exhaust flow window compared to the 11-blade design. This makes it easier for exhaust gases to exit, reducing back pressure and heat buildup. The result is a more efficient turbo system with less thermal stress. -
Ideal for Turbo Upgrades:
When upgrading to a larger compressor wheel for increased airflow, the turbine side must also be able to handle the extra exhaust volume. The 9-blade wheel is better suited for this, as the factory 11-blade turbine can create a bottleneck, leading to high back pressure, potential power loss, and even turbine failure over time.
