When it comes to improving performance, increased airflow is a key ingredient. Available in 92mm or 102mm diameters, 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 on this Corvette part 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.
• New throttle body designed to work in conjunction with the new 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.
