When it comes to improving performance, increased airflow is a key ingredient. The Big Mouth Throttle Body increases airflow through a series of innovative design changes and slightly enlarged throttle opening. Significant testing and engineering was conducted to optimize cross-sectional flow and eliminate airflow turbulence, especially at part-throttle operation.
The throttle blade's increased thickness eliminates deflection, especially in boosted applications. To improve throttle response, the blade pivot is offset, while the beefed up linkage and dual throttle spring mechanism ensure total throttle control.
Features & Benefits:
Designed to work with FAST™ LSX™ 92mm & LSXR 102mm Intake Manifolds
Better airflow than OEM or aftermarket 90mm units due to enlarged throttle opening & modified internal design
Dual spring mechanism & beefed up linkage for total throttle control
Increased thickness of both the throttle blade & the shaft resists deflection, especially in boosted applications
Offset blade pivot allows for smoother operations & significantly improves throttle response
