EFISupply handles many popular sizes of "monoblade" type throttle bodies. While carburetors are better undersized than oversized, the same cannot be said for EFI throttle bodies. Using an undersized throttle body will unnecessarily restrict airflow. Care should be taken to avoid going too large however as using too large a throttle body will result in a lack of throttle "resolution" or sensitivity and may negatively impact drivability.

When it comes to improving your engine’s performance, increased airlow is a key ingredient. The FAST Big Mouth Throttle Bodies for the FAST LSX 92mm & LSXR 102mm Intake Manifolds increase airflow through a series of innovative design changes and a slightly enlarged throttle opening. FAST 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 FAST Big Mouth 92mm Throttle Body will deliver bolt-on GM Gen III (LS-1, 2, 6) horsepower while the LSX is is designed to maximize potential performance upgrades on L92/LS3/LS7 engines.
