New 92mm throttle body design incorporates major upgrades, including redesigned linkage for smoother operation and improved throttle response

When it comes to improving your engine’s performance, increased airflow is generally a key ingredient. The newly released FAST™ Big Mouth Throttle Body™ for the FAST™ LSX™ 92mm Intake Manifold increases airflow through a series of innovative design changes and a slightly enlarged throttle opening. When used with the new FAST™ LSX™ 92mm Intake Manifold, FAST™ has put their “manifold where their mouth is” in terms of enhanced engine performance and drivability.

But the increased size of the FAST™ Big Mouth Throttle Body™ is just a small part of the added benefits. FAST™ invested significant testing and 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 new FAST™ Big Mouth Throttle Body™ will deliver bolt-on GM Gen III (LS1, -2 & -6) horsepower and maximize the potential of performance upgrades.
