FAST™ 102mm Big Mouth Throttle Body™

Memphis, TN – The 102mm FAST™ Big Mouth Throttle Body™ is designed to maximize performance upgrades on all GM Gen III and Gen IV engines with cable driven throttle bodies.

FAST™ knows that increased airflow is a key ingredient to increasing your engine’s performance. The FAST™ Big Mouth Throttle Body™ is designed to work in conjunction with the LSXR™ and LSXRT™ 102mm Manifolds, and increases airflow through a series of innovative design changes and a throttle opening nearly 40 percent larger than stock. It also offers increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage with dual throttle spring mechanism ensures total throttle control. What’s more, FAST™ invested significant testing and engineering resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part-throttle operation.
