When it comes to improving your engine's performance, increased airflow is a key ingredient. The FASTT Big Mouth Throttle BodiesT for the FASTT LSXT 92mm & LSX_RT 102mm Intake Manifolds increase airflow through a series of innovative design changes and a slightly enlarged throttle opening. FASTT also invested significant testing & engineering resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part throttle operation.

In addition, these throttle bodies offer 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 and dual throttle spring mechanism ensure total throttle control. The FASTT Big Mouth 92mm Throttle BodyT will deliver bolton GM Gen III (LS1, -2 & -6) horsepower while the LSX_RT is designed to maximize potential performance upgrades on L92/LS3/LS7 engines.
